Instrument Panel, Gauges and Warning Indicators: Testing and Inspection
Adaptation Of Vehicle Identification Number (VIN), Performing (Adaptation Channel 81)
NOTE:
- The "adaptation" function has to be carried out on A/C control heads -E87- that display the malfunction "control module incorrect VIN".
- A new replacement A/C control head -E87- is supplied without VIN. The VIN transferred via the CAN-bus comfort system is entered and saved in the A/C control head -E87- when the ignition is first switched on after the installation.
- If an A/C control head -E87- is to be installed into another vehicle, the transmitted and saved VIN no longer matches, the -E87- recognizes this and stores the malfunction "Control module incorrect VIN). The VIN that is saved in the A/C control head -E87- is erased by entering the PIN-number during the adaptation function.
- The adaptation of the A/C control head -E87- can only be carried out by entering the designated PIN-number.
Requirements
- Battery completely charged.
- Check coding of Control module with indicator unit in instrument cluster -J285-, the coding corresponds to the vehicle model and vehicle equipment
- Check Vehicle Identification Number (VIN). The VIN corresponding to the vehicle must be saved in the Control module with indicator unit in instrument cluster -J285-.
Carry out adaptation
- Check DTC memory of A/C control head -E87- and if necessary eliminate all possible displayed malfunctions (the malfunction "Control module incorrect VIN" cannot be erased now). Displaying & Reading Trouble Codes
- Check coding of A/C control head -E87- for vehicle equipment options and correct if necessary. Code Control Module (Function 07)

- End On Board Diagnostic (OBD) and switch ignition off. End Output (Function 06)
- Start engine.
- Check DTC memory of A/C control head -E87- erase displayed malfunctions. Displaying & Reading Trouble Codes Clearing Trouble Codes
The malfunction "Control module incorrect VIN" is no longer displayed, or the malfunction can now be erased (if adaptation was carried out correctly).
- Now check the VIN that was saved in the A/C control module -E87- (function "Read Measuring Value Block", display group 081). Display Group 081
