Hər bir istehsalçı yuxarıdakı əlavə rejimi müəyyənləşdirə bilər #9 (E.G.: rejissor 22 SAE J2190 tərəfindən FORD / GM üçün təyin olunduğu kimi, rejissor 21 Toyota üçün) Digər məlumatlar üçün E.G. dartma batareyasının gərginliyi a Hibrid elektrikli nəqliyyat vasitəsi (Hev).^[2]

Standart pidlər

Aşağıdakı cədvəl SAE J1979 tərəfindən müəyyən edilmiş standart OBD-II pidləri göstərir. Hər bir pidə üçün gözlənilən cavab verilir, Cavabı mənalı məlumatlara necə tərcümə etmək barədə məlumatla yanaşı. Yenidən, Bütün nəqliyyat vasitələri bütün pidləri dəstəkləməyəcək və orada OBD-II standartında müəyyənləşdirilməyən xüsusi pidlər ola bilər.

Qeydlər 1 və 2 əsasən eynidır, Bu rejimdən başqa 1 Cari məlumat verir, halbuki rejimi 2 Son diaqnostik problem kodu təyin edildiyi nöqtədə eyni məlumatların görüntüsünü təmin edir. İstisnalar piddir 01, yalnız rejimdə mövcuddur 1, və pid 02, yalnız rejimdə mövcuddur 2. Əgər rejim 2 Pid 02 sıfır qayıdır, Sonra heç bir görüntü və bütün digər rejim yoxdur 2 Məlumat mənasızdır.

Bit kodlu-notation istifadə edərkən, C4 kimi miqdar bir az deməkdir 4 Məlumat Byte c. Hər bit çoxdur 0 qədər 7, beləcə 7 ən əhəmiyyətlidir və 0 ən az əhəmiyyətlidir.

Bitwise encoded PIDs

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:

Rejissor 1 Pid 00

A request for this PID returns 4 bytes of data. Each bit, from MSB qədər LSB, represents one of the next 32 PIDs and is giving information about if it is supported.

For example, if the car response is BE1FA813, it can be decoded like this:

Hexadecimal	B				E				1				F				A				8				1				3
Binary	1	0	1	1	1	1	1	0	0	0	0	1	1	1	1	1	1	0	1	0	1	0	0	0	0	0	0	1	0	0	1	1

PID number	01	02	03	04	05	06	07	08	09	0A	0B	0C	0D	0E	0F	10	11	12	13	14	15	16	17	18	19	1A	1B	1C	1D	1E	1F	20

So, supported PIDs are: 01, 03, 04, 05, 06, 07, 0C, 0D, 0E, 0F, 10, 11, 13, 15, 1C, 1F və 20

Rejissor 1 Pid 01

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 A0represent 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) parça.

Bit	ad	Definition
A7	Mil	Off or On, indicates if the CEL/MIL is on (or should be on)
A6–A0	DTC_CNT	Number of confirmed emissions-related DTCs available for display.
B7	RESERVED	Reserved (should be 0)
B3	NO NAME	0 = 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.

	Test available	Test incomplete
Components	B2	B6
Fuel System	B1	B5
Misfire	B0	B4

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

The bytes C and D for spark ignition monitors (e.g. Otto or Wankel engines):

	Test available	Test incomplete
EGR System	C7	D7
Oxygen Sensor Heater	C6	D6
Oksigen sensoru	C5	D5
A/C Refrigerant	C4	D4
Secondary Air System	C3	D3
Evaporative System	C2	D2
Heated Catalyst	C1	D1
Catalyst	C0	D0

And the bytes C and D for compression ignition monitors (Diesel engines):

	Test available	Test incomplete
EGR and/or VVT System	C7	D7
PM filter monitoring	C6	D6
Exhaust Gas Sensor	C5	D5
– Reserved –	C4	D4
Boost Pressure	C3	D3
– Reserved –	C2	D2
NOx/SCR Monitor	C1	D1
NMHC Catalyst[bir]	C0	D0

Rejissor 1 Pid 41

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) parça.

Here are the common bit B definitions, they are test based.

	Test available	Test incomplete
Components	B2	B6
Fuel System	B1	B5
Misfire	B0	B4

The bytes C and D for spark ignition monitors (e.g. Otto or Wankel engines):

	Test available	Test incomplete
EGR System	C7	D7
Oxygen Sensor Heater	C6	D6
Oksigen sensoru	C5	D5
A/C Refrigerant	C4	D4
Secondary Air System	C3	D3
Evaporative System	C2	D2
Heated Catalyst	C1	D1
Catalyst	C0	D0

And the bytes C and D for compression ignition monitors (Diesel engines):

	Test available	Test incomplete
EGR and/or VVT System	C7	D7
PM filter monitoring	C6	D6
Exhaust Gas Sensor	C5	D5
– Reserved –	C4	D4
Boost Pressure	C3	D3
– Reserved –	C2	D2
NOx/SCR Monitor	C1	D1
NMHC Catalyst[bir]	C0	D0

Rejissor 1 Pid 78

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:

Byte	təsvir
A	Supported EGT sensors
B–C	Temperature read by EGT11
D–E	Temperature read by EGT12
F–G	Temperature read by EGT13
H–I	Temperature read by EGT14

The first byte is bit-encoded as follows:

Bit	təsvir
A7–A4	Reserved
A3	EGT bank 1, sensor 4 Dəstəklənir?
A2	EGT bank 1, sensor 3 Dəstəklənir?
A1	EGT bank 1, sensor 2 Dəstəklənir?
A0	EGT bank 1, sensor 1 Dəstəklənir?

The remaining bytes are 16 bit integers indicating the temperature in degrees Celsius in the range -40 qədər 6513.5 (scale 0.1), using the usual {\sərnişin (A\times 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.

Rejissor 3 (no PID required)

A request for this mode 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–A6	First DTC character
00	P – Powertrain
01	C – Chassis
10	B – Body
11	U – Network

The two following digits are encoded as 2 bitlər. The second character in the DTC is a number defined by the following table:

A5–A4	Second DTC character
00	0
01	1
10	2
11	3

The third character in the DTC is a number defined by

A3–A0	Third DTC character
0000	0
0001	1
0010	2
0011	3
0100	4
0101	5
0110	6
0111	7
1000	8
1001	9
1010	A
1011	B
1100	C
1101	D
1110	E
1111	F

The fourth and fifth characters are defined in the same way as the third, but using bits B7–B4 və 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.

Rejissor 9 Pid 08

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 (2) bytes and are reported in this order (each message contains two items, hence the message length is 4).

Enumerated PIDs[edit]

Some PIDs are to be interpreted specially, and aren’t necessarily exactly bitwise encoded, or in any scale. The values for these PIDs are enumerated.

Rejissor 1 Pid 03[edit]

A request for this PID returns 2 bytes of data. The first byte describes fuel system #1.

Value	təsvir
1	Open loop due to insufficient engine temperature
2	Closed loop, using oxygen sensor feedback to determine fuel mix
4	Open loop due to engine load OR fuel cut due to deceleration
8	Open loop due to system failure
16	Closed loop, using at least one oxygen sensor but there is a fault in the feedback system

Any other value is an invalid response. There can only be one bit set at most.

The second byte describes fuel system #2 (if it exists) and is encoded identically to the first byte.

Non-standard PIDs

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 America	Annual 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:^[4][5]

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.

BACARMAQ (11-parça) bus format

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

The functional PID query is sent to the vehicle on the CAN bus at ID 7DFh, using 8 data bytes. The bytes are:

	Byte
PID Type	0	1	2	3	4	5	6	7
SAE Standard	Number of additional data bytes: 2	Rejissor 01 = show current data; 02 = freeze frame; s.	PID code (E.G.: 05 = Engine coolant temperature)	Istifadə edilmir (may be 55h)
Vehicle specific	Number of additional data bytes: 3	Custom mode: (E.G.: 22 = enhanced data)	PID code (E.G.: 4980h)		Istifadə edilmir (may be 00h or 55h)

Response

The 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, s. 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:

	Byte
PID Type	0	1	2	3	4	5	6	7
SAE Standard 7E8h, 7E9h, 7EAh, s.	Number of additional data bytes: 3 qədər 6	Custom mode Same as query, except that 40h is added to the mode value. So: 41h = show current data; 42h = freeze frame; s.	PID code (E.G.: 05 = Engine coolant temperature)	value of the specified parameter, byte 0	value, byte 1 (isteğe bağlı)	value, byte 2 (isteğe bağlı)	value, byte 3 (isteğe bağlı)	Istifadə edilmir (may be 00h or 55h)
Vehicle specific 7E8h, or 8h + physical ID of module.	Number of additional data bytes: 4qədər 7	Custom mode: same as query, except that 40h is added to the mode value.(E.G.: 62h = response to mode 22h request)	PID code (E.G.: 4980h)		value of the specified parameter, byte 0	value, byte 1 (isteğe bağlı)	value, byte 2 (isteğe bağlı)	value, byte 3 (isteğe bağlı)
Vehicle specific 7E8h, or 8h + physical ID of module.	Number of additional data bytes: 3	7Fh this a general response usually indicating the module doesn’t recognize the request.	Custom mode: (E.G.: 22h = enhanced diagnostic data by PID, 21h = enhanced data by offset)	31h	Istifadə edilmir (may be 00h)
