Adaptation of Vehicle Identification Number (VIN), Performing (Adaptation Channel "81" )
Adaptation Of Vehicle Identification Number (VIN), Performing (adaptation Channel "81" )
NOTE:
- The "Adaptation" function must be performed for operating and display modules, Climatronic Control Module J255 as of hardware/software version "0711" for which the malfunction "Control module incorrect Vehicle Identification Number (VIN)" is displayed.
- New replacement operating and display modules, Climatronic Control Module J255 are supplied without VIN coding. The first time the ignition is switched on following installation, the VIN transmitted via the CAN-Bus comfort system is read into the operating and display module, Climatronic Control Module J255 (as of hardware/software version "0711") and stored (anti-theft protection).
- If an operating and display module, Climatronic Control Module J255 (as of hardware/software version "0711") is installed in a different vehicle (e.g. swapped over), the transmitted and stored VINs no longer coincide and the malfunction "Control module incorrect Vehicle Identification Number (VIN)" is stored in the operating and display module, Climatronic Control Module J255. Entering the PIN in the adaptation function erases the VIN stored in the operating and display module, Climatronic Control Module J255.
- The operating and display module, Climatronic Control Module J255 can only be adapted by entering the specified PIN.
Requirements
- Battery fully charged
- Check coding in Instrument Cluster Control Module J285 ; this corresponds to vehicle model and equipment "Guided Fault-Finding" Vehicle Diagnosis, Testing Info. System VAS5051B or Vehicle Diagnosis Service Syst. VAS5052.
- Check VIN. The correct VIN for the vehicle must have been stored in the Instrument Cluster Control Module J285 "Guided Fault-Finding" Vehicle Diagnosis, Testing Info. System VAS5051B or Vehicle Diagnosis Service Syst. VAS5052.
Adaptation procedure
- Check DTC memory of operating and display module, Climatronic Control Module J255 and rectify any other malfunctions displayed (fault "Control module incorrect Vehicle Identification Number (VIM)" cannot be erased at this stage). Displaying & Reading Trouble Codes
- Check coding of operating and display module, Climatronic Control Module J255 for vehicle-specific optional extras and correct if necessary.
Indicated on display of Diagnostic Operation System VAS 5051A:
- Select function "10 - Adaptation".
Indicated on display of Diagnostic Operation System VAS 5051A
- Prompt for entering channel number appears in display zone -1 -.
- Input keypad appears in display zone - 2 -.
- Use input keypad in display zone - 2 - to enter "81" for channel "81" and confirm by touching Q key.
NOTE:
- Possible causes if display zone -1 - indicates "Function unknown or cannot be implemented at present":
- - Control unit adaptation not performed as specified and in full - 1 - Malfunction on CAN-Bus comfort system
- If display zone -1 - indicates "Disabled" and disable time (e.g. "10" for 10 minutes), the adaptation function is currently not available due to having been incorrectly implemented several times.
- Wait for completion of disable time.

- Display field -1 - indicates "Channel 81 reading and testing". - Display in area - 2 - is "PIN ?".
- A bar appears in area - 3 - (not to be used for this application).
- Touch key - 4 - (for entry via keypad).
Indicated on display of Diagnostic Operation System VAS 5051A
- Display field -1 - indicates "Enter adaptation value: 0 to XXXXX".
- Input keypad appears in display zone - 2 -.
- Use input keypad in display zone - 2 - to enter PIN for re-adaptation of operating and display module, Climatronic Control Module J255.
PIN:"26467"
- PIN entered appears in area - 2 -.
- Confirm entry by touching Q key.
Indicated on display of Diagnostic Operation System VAS 5051A :
- The PIN entered appears above the bar in area - 3 -.
- Store entry by touching key - 5 -.
Indicated on display of Diagnostic Operation System VAS 5051A
- Display field -1 - indicates "Store channel 81".
- Area - 3 - displays the original PIN or "0" and the new PIN.
- Adopt and store entry by touching key - 4 -.
- Display field -1 - indicates "Store channel 1, value 1 stored".
NOTE:
- Touch <- key to return to selection program.
- Entering the PIN erases the VIN stored in the operating and display module, Climatronic Control Module J255. The operating and display module, Climatronic Control Module J255 is then ready to adopt the VIN transmitted by the Instrument Cluster Control Module J285 via the CAN-Bus comfort system.
- Terminate On Board Diagnostic (OBD) and switch off ignition.
- Start engine.
- Check DTC memory of operating and display module, Climatronic Control Module J255 and erase faults displayed. Displaying & Reading Trouble Codes
Clearing Trouble Codes
The malfunction "Control module incorrect Vehicle Identification Number (VIN)" is no longer displayed or can now be erased (if adaptation has been performed correctly).
- Check the VIN now stored in the operating and display module, Climatronic Control Module J255 (Reading measuring value block, display group "081").
