obdsp n

Sets the protocol used by the OBDII transmitter.

n = 0	Automatic
n = 1	SAE J1850 PWM
n = 2	SAE J1850 VPW
n = 3	ISO 9141-2
n = 4	ISO 14230-4 KWP (slow)
n = 5	ISO 14230-4 KWP (fast)
n = 6	ISO 15765-4 CAN (11 bit ID, 500 Kbaud)
n = 7	ISO 15765-4 CAN (29 bit ID, 500 Kbaud)
n = 8	ISO 15765-4 CAN (11 bit ID, 250 Kbaud)
n = 9	ISO 15765-4 CAN (29 bit ID, 250 Kbaud)
n = 10	SAE J1939 CAN (29 bit ID, 250 Kbaud)
n = 11	USER1 CAN (11 bit ID, 125 Kbaud)
n = 12	USER2 CAN (11 bit ID, 50 Kbaud)

Notes:

Option 0 (Automatic) only replaces OBD2 protocol options 1-9. Some vehicles may exhibit problems with automatic protocol discovery. obdsp must specifically be set to match the protocol on those vehicles.
This command only applies to the Engine Vehicle Diagnostic Transmitter (E-VDT) WPAN device

Examples:

Set the OBDII transmitter to use the J1939 protocol :
cmd obdsp 10
