OBD packet format
(ASCII code)
OBD packet has five different format, they are:
1. CAN 11bits 250
2. CAN 29bits 250
3. CAN 11bits 500
4. CAN 29bits 500
5.Scanning
Each format has its input code, they are:
CAN 11bits 250:
A
CAN 29bits 250:
B
CAN 11bits 500:
C
CAN 29bits 500:
D
Scanning:
Z
Example 1: To get PID=0104 from CAN 29bits 500 format
Input:
D0104+CR
(Use
ASCII code
as the input format of the firmware)
Output:
CAN 29bits 500,0104 18DAF111 08 0241040000000000
+LF+CR
(Use
ASCII code
as the input format of the firmware)
□ ID number □ Key-in value
□ ID □ Len
□ Data
Other Information:
Data include eight different bytes
Byte 1: Data include some return information. For example,
1. 18DAF110 08
06
4100BE1B3013
00
Byte1 is 06 followed by six non-zero values.
2. 18DAF110 08
03
410432
00000000
Byte1 is 03 followed by three non-zero values.
Byte 2: Mode is related with the Key-in value. For example:
01
04 18DAF110 08 03
41
043200000000
Key-in value is 01, Byte 2 value will change to 41. The main difference is: 0 means to
send out by query side, 4 means to send out by receiver side
Byte 3: PID is the same with the Key-in value. For example:
01
04
18DAF110 08 0341
04
3200000000
Key-in value is 04, Byte 3 value will be 04.
