Control module, coding (function 07)

When replacing instrument clusters, the CAN- bus On Board Diagnostic Interface -J533- must be coded according to vehicle market version and equipment level variables.


NOTE: When replacing instrument clusters, CAN-bus On Board Diagnostic interface coding must always be performed, regardless if the correct code is already stored/appears in the display after inputting address word 79 - Gateway.


Coding
- Input address word 19 "Gateway" and then press -> button until "Select function XX" is shown in display.

Indicated on display:

07-Code Control Module


- Press -Q- button to confirm input.

Indicated on display:

- Enter code number compiled from code table

Code table

Control Modules Code number:
connected to CAN-Bus
Automatic Transmission (TCM) 00001
Airbag 00004

Add applicable control module code numbers together to determine the final coding value.


CAUTION!
- Through January 2000, Gateway coding software did not account for the presence of the ABS control module (as part of the CAN-bus network). Therefore, the DTC "01044 Control Module incorrectly coded" is loaded into memory. Ignore this DTC!
- For vehicles through January 2000, DO NOT recode the ABS control module or attempt to use Gateway code values other than those given in the table above!
- This software issue was repaired as of February 2000, but still DO NOT recode the ABS control module.


Example: TCM + Airbag: 00001 + 00004 = 00005

- Use VAG 1551/1552 button pad to enter code: 00005

Indicated on display:


Coding control module Q
Enter code number 00005 (0-32000)


- Press -Q- button to confirm input.
