After you read this financial assistance article you MUST take action and apply for some of the programs or at least make contact asking them for help. If you're struggling with your finances there should be no shame in admitting this so you can get over your financial hardship quicker. I have included some very useful links so make sure you bookmark the article or share it with others that need help, I also have more articles on getting money for college, medical bills, and money if you're pregnant and have no money. Also if you want ideas to supplement your income check out the following posts. All these ideas are legal and legitimate and I have used these strategies myself to increase my passive income stream.

Government Assistance/Public AssistanceNeed Help Paying Bills:If you need help with money right now and have nowhere to go you should turn to the government for help. Public assistance is available for people who are struggling with their finances and need help, you could get assistance towards your food in the form of food stamps, this program is called the Supplemental Nutrition Assistance Program. You could also apply for unemployment benefits if you've lost your job through no fault of your own. You could get help towards your Utility Bills through the LIHEAP Program (Low Income Home Energy Assistance Program). The list below shows all the help that you might be eligible for if you're on a low income or near the Federal poverty line

+ Food Stamps (Check: Supplemental Nutrition Assistance Program)
+ LIHEAP Program (Check: Low Income Home Energy Assistance Program)
+ Rental Assistance (Check: Department of Housing and Urban Development)

Need Help With Rent:You could get help with rent or mortgage through the rental assistance program offered by the US Housing & Urban Development Department (HUD). A number of other programs could help starting from Weatherization programs from LIHEAP which helps with utility bills, this program has helped families stay warm in winter and cool in the summer. You can also find military financial assistance, financial assistance for pensioners, mortgage assistance programs and advice on debt consolidation and debt management.

Charities/Foundations Giving Money AwayAnther option you have if you need money right now is to visit your local charity or community foundation. In the past when I needed help paying bills I would turn to these organizations for help. These agencies have a money set aside to help people who are struggling financially. If you're not eligible for financial assistance you could be eligible for other help. Many charities offer help with food, clothes, emergency accommodation and much more. They can also offer advice which will help you improve your circumstances much quicker.

Churches & Religious Bodies Giving MoneyReligious organizations like churches, synagogues, mosques all have financial assistance plans, it might be little known but these organizations help a number of people. If you were not eligible for public or private assistance you could go to these places of worship for help. Most places of worship have their own discretionary fund to help people who need help with money right now. Make a list of all the religious places of worship and then ask them for assistance one by one. Here are some charities and religious organizations you should definitely check out. I have seen countless people visit my place of worship when they need help with money.

1. Community Action Organization
2. St Vincent De Paul
3. Red Cross
4. United Way
5. Catholic Charities
6. Salvation Army

Friends & FamilyThis could be the least popular option as the last people you want to bother with your problems and friends and families. It might surprise you to know that these people are really willing to help and if you go to them with a legitimate problem they will help you with money right now. You could ask them for a loan and then write a loan contract agreement of promissory note to make sure the relationship stays intact if you're unable to repay them.

Millionaires Giving Money/Begging Sites/Giving SitesAnother option you have for financial assistance is asking millionaires/billionaires and philanthropists for help. You can find hundreds of charitable foundations in the USA, most of them offer emergency financial assistance to people who need money now. 

You should also try sites such as Fund Anything which was founded by Donald Trump. This site allows you to create a video to ask for funding for virtually anything. A lot of people have used this service and received the funds that they require to get out of hardship.

You should also consider sites such as YouTube. Creating a video asking rich people for help is another way to reach out to solve your financial problems. You might be surprised to know that many people are doing this as we speak and getting help with their financial hardship. One individual who goes by the name of Craig Rowin was able to secure a one million dollar donation just by asking for financial assistance on YouTube.

Begging sites and giving sites are great to raise money if you're experiencing poverty, crisis or even terminal illnesses. You can use these sites to post your hardship and then ask for help by giving people the option to donate, if you can promote this all over the internet then you could raise a lot of money. If you need help with money right now there are a number of options you could explore, the key is being proactive and always looking for ways to get yourself out of hardship and live a better life. 


Taking out a Short Term LoanIf you've exhausted all avenues the only alternative you might have is to take out a loan. You should always try to borrow money interest-free from friends and family. You can also take advantage of zero percent interest credit cards which offer free finance. If you cannot take out an interest-free loan you should use a comparison site to find the best payday loan company offering the lowest possible APR. As always you should be aware of how much you are borrowing and how much you will have to repay. You should also complete an income and expenses statement to find out how much disposable income you have to cover your loan repayments. Never take out a loan you cannot service otherwise your loan will spiral out of control. 




Earn More Money
Asking for financial assistance is only one side of the coin. You should try to earn as much money as you can to get yourself out of financial hardship. If you're determined and put your mind to it you can earn whatever you want if you give it enough time and patience. I have written a number of posts which share ideas on how to make money very quickly. All these ideas and strategies are completely legal and legitimate and you will make money if you're determined. Check out some of these posts for inspiration and motivation.

OBD-II PIDs (On-board diagnosticsParameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.
SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissionsinspections. Manufacturers also define additional PIDs specific to their vehicles. Though not mandated, many motorcycles also support OBD-II PIDs.
In 1996, light duty vehicles (less than 8,500 lb [3,900 kg]) were the first to be mandated followed by medium duty vehicles (between 8,500–14,000 lb [3,900–6,400 kg]) in 2005.[1] They are both required to be accessed through a standardized data link connector defined by SAE J1962.
Heavy duty vehicles (greater than 14,000 lb [6,400 kg]) made after 2010,[1] for sale in the US are allowed to support OBD-II diagnostics through SAE standard J1939-13 (a round diagnostic connector) according to CARB in title 13 CCR 1971.1. Some heavy duty trucks in North America use the SAE J1962 OBD-II diagnostic connector that is common with passenger cars, notably Mack and Volvo Trucks, however they use 29 bit CAN identifiers (unlike 11 bit headers used by passenger cars).
Services / Modes[edit]There are 10 diagnostic services described in the latest OBD-II standard SAE J1979. Before 2002, J1979 referred to these services as 'modes'. They are as follows:
Service / Mode (hex)Description
01Show current data
02Show freeze frame data
03Show stored Diagnostic Trouble Codes
04Clear Diagnostic Trouble Codes and stored values
05Test results, oxygen sensor monitoring (non CAN only)
06Test results, other component/system monitoring (Test results, oxygen sensor monitoring for CAN only)
07Show pending Diagnostic Trouble Codes (detected during current or last driving cycle)
08Control operation of on-board component/system
09Request vehicle information
0APermanent Diagnostic Trouble Codes (DTCs) (Cleared DTCs)
Vehicle manufacturers are not required to support all services. Each manufacturer may define additional services above #9 (e.g.: service 22 as defined by SAE J2190 for Ford/GM, service 21 for Toyota) for other information e.g. the voltage of the traction battery in a hybrid electric vehicle (HEV).[2]
The nonOBD UDS services start at 0x10 to avoid overlap of ID-range.
Standard PIDs[edit]The table below shows the standard OBD-II PIDs as defined by SAE J1979. The expected response for each PID is given, along with information on how to translate the response into meaningful data. Again, not all vehicles will support all PIDs and there can be manufacturer-defined custom PIDs that are not defined in the OBD-II standard.
Note that services 01 and 02 are basically identical, except that service 01 provides current information, whereas service 02 provides a snapshot of the same data taken at the point when the last diagnostic trouble code was set. The exceptions are PID 01, which is only available in service 01, and PID 02, which is only available in service 02. If service 02 PID 02 returns zero, then there is no snapshot and all other service 02 data is meaningless.
When using Bit-Encoded-Notation, quantities like C4 means bit 4 from data byte C. Each bit is numerated from 0 to 7, so 7 is the most significant bit and 0 is the least significant bit (See below).

Bitwise encoded PIDs[edit]Some of the PIDs in the above table cannot be explained with a simple formula. A more elaborate explanation of these data is provided here:
Service 01 PID 00[edit]A request for this PID returns 4 bytes of data (Big-endian). Each bit, from MSB to LSB, represents one of the next 32 PIDs and specifies whether that PID is supported.
For example, if the car response is BE1FA813, it can be decoded like this:
HexadecimalBE1FA813
Binary10111110000111111010100000010011

So, supported PIDs are: 01, 03, 04, 05, 06, 07, 0C, 0D, 0E, 0F, 10, 11, 13, 15, 1C, 1F and 20
Service 01 PID 01[edit]A request for this PID returns 4 bytes of data, labeled A B C and D.
The first byte(A) contains two pieces of information. Bit A7 (MSB of byte A, the first byte) indicates whether or not the MIL (check engine light) is illuminated. Bits A6 through A0 represent the number of diagnostic trouble codes currently flagged in the ECU.
The second, third, and fourth bytes(B, C and D) give information about the availability and completeness of certain on-board tests. Note that test availability is indicated by set (1) bit and completeness is indicated by reset (0) bit.
BitNameDefinition
A7MILOff or On, indicates if the CEL/MIL is on (or should be on)
A6-A0DTC_CNTNumber of confirmed emissions-related DTCs available for display.
B7RESERVEDReserved (should be 0)
B3NO NAME0 = Spark ignition monitors supported (e.g. Otto or Wankel engines)
1 = Compression ignition monitors supported (e.g. Diesel engines)
Here are the common bit B definitions, they are test based.

Fuel SystemB1B5

The third and fourth bytes are to be interpreted differently depending on if the engine is sparkignition (e.g. Otto or Wankel engines) or compression ignition (e.g. Diesel engines). In the second (B) byte, bit 3 indicates how to interpret the C and D bytes, with 0 being spark (Otto or Wankel) and 1 (set) being compression (Diesel).

Service 01 PID 41[edit]A request for this PID returns 4 bytes of data. The first byte is always zero. The second, third, and fourth bytes give information about the availability and completeness of certain on-board tests. As with PID 01, the third and fourth bytes are to be interpreted differently depending on the ignition type (B3) – with 0 being spark and 1 (set) being compression. Note again that test availability is represented by a set (1) bit and completeness is represented by a reset (0) bit.

Service 01 PID 78[edit]A request for this PID will return 9 bytes of data.The first byte is a bit encoded field indicating which EGT sensors are supported: Music tags pro 1 0 0 – id3 batch editor.
ByteDescription
ASupported EGT sensors
B-CTemperature read by EGT11
D-ETemperature read by EGT12
F-GTemperature read by EGT13
H-ITemperature read by EGT14
The first byte is bit-encoded as follows:
BitDescription
A7-A4Reserved
A3EGT bank 1, sensor 4 Supported?
A2EGT bank 1, sensor 3 Supported?
A1EGT bank 1, sensor 2 Supported?
A0EGT bank 1, sensor 1 Supported?
The remaining bytes are 16 bit integers indicating the temperature in degrees Celsius in the range -40 to 6513.5 (scale 0.1), using the usual (A×256+B)/10−40{displaystyle (Atimes 256+B)/10-40} formula (MSB is A, LSB is B). Only values for which the corresponding sensor is supported are meaningful.
The same structure applies to PID 79, but values are for sensors of bank 2.
Service 03 (no PID required)[edit]A request for this service returns a list of the DTCs that have been set. The list is encapsulated using the ISO 15765-2 protocol.
If there are two or fewer DTCs (4 bytes) they are returned in an ISO-TP Single Frame (SF). Three or more DTCs in the list are reported in multiple frames, with the exact count of frames dependent on the communication type and addressing details.
Each trouble code requires 2 bytes to describe. The text description of a trouble code may be decoded as follows. The first character in the trouble code is determined by the first two bits in the first byte:
A7-A6First DTC character
00P - Powertrain
01C - Chassis
10B - Body
11U - Network
The two following digits are encoded as 2 bits. The second character in the DTC is a number defined by the following table:
A5-A4Second DTC character
000
011
102
113
The third character in the DTC is a number defined by
A3-A0Third DTC character
00000

00102
00113
01004

10019
1010A
1011B
1100C
1101D
1110E
1111F
The fourth and fifth characters are defined in the same way as the third, but using bits B7-B4 and B3-B0. The resulting five-character code should look something like 'U0158' and can be looked up in a table of OBD-II DTCs. Hexadecimal characters (0-9, A-F), while relatively rare, are allowed in the last 3 positions of the code itself.
Service 09 PID 08[edit]It provides information about track in-use performance for catalyst banks, oxygen sensor banks, evaporative leak detection systems, EGR systems and secondary air system.
The numerator for each component or system tracks the number of times that all conditions necessary for a specific monitor to detect a malfunction have been encountered.The denominator for each component or system tracks the number of times that the vehicle has been operated in the specified conditions.
The count of data items should be reported at the beginning (the first byte).
All data items of the In-use Performance Tracking record consist of two bytes and are reported in this order (each message contains two items, hence the message length is 4).

Non-standard PIDs[edit]The majority of all OBD-II PIDs in use are non-standard. For most modern vehicles, there are many more functions supported on the OBD-II interface than are covered by the standard PIDs, and there is relatively minor overlap between vehicle manufacturers for these non-standard PIDs.
There is very limited information available in the public domain for non-standard PIDs. The primary source of information on non-standard PIDs across different manufacturers is maintained by the US-based Equipment and Tool Institute and only available to members. The price of ETI membership for access to scan codes varies based on company size defined by annual sales of automotive tools and equipment in North America:
Annual Sales in North AmericaAnnual Dues
Under $10,000,000$5,000
$10,000,000 - $50,000,000$7,500
Greater than $50,000,000$10,000
However, even ETI membership will not provide full documentation for non-standard PIDs. ETI state:[7][8]
Some OEMs refuse to use ETI as a one-stop source of scan tool information. They prefer to do business with each tool company separately. These companies also require that you enter into a contract with them. The charges vary but here is a snapshot as of April 13th, 2015 of the per year charges:
GM$50,000
Honda$5,000
Suzuki$1,000
BMW$25,500 plus $2,000 per update. Updates occur annually.
CAN (11-bit) bus format[edit]The PID query and response occurs on the vehicle's CAN bus. Standard OBD requests and responses use functional addresses. The diagnostic reader initiates a query using CAN ID 7DFh[clarification needed], which acts as a broadcast address, and accepts responses from any ID in the range 7E8h to 7EFh. ECUs that can respond to OBD queries listen both to the functional broadcast ID of 7DFh and one assigned ID in the range 7E0h to 7E7h. Their response has an ID of their assigned ID plus 8 e.g. 7E8h through 7EFh.
This approach allows up to eight ECUs, each independently responding to OBD queries. The diagnostic reader can use the ID in the ECU response frame to continue communication with a specific ECU. In particular, multi-frame communication requires a response to the specific ECU ID rather than to ID 7DFh.
CAN bus may also be used for communication beyond the standard OBD messages. Physical addressing uses particular CAN IDs for specific modules (e.g., 720h for the instrument cluster in Fords) with proprietary frame payloads.
Query[edit]The functional PID query is sent to the vehicle on the CAN bus at ID 7DFh, using 8 data bytes. The bytes are:

Monitor 200Response[edit]Monitor 2080The vehicle responds to the PID query on the CAN bus with message IDs that depend on which module responded. Typically the engine or main ECU responds at ID 7E8h. Other modules, like the hybrid controller or battery controller in a Prius, respond at 07E9h, 07EAh, 07EBh, etc. These are 8h higher than the physical address the module responds to. Even though the number of bytes in the returned value is variable, the message uses 8 data bytes regardless (CAN bus protocol form Frameformat with 8 data bytes).The bytes are:
