Test 1: Fault in CAN communication with control unit A1 (Instrument cluster).
1. Fault in CAN communication with control unit A1 (Instrument cluster).
Operation number of operation texts and work units or standard texts and flat rates:27-0641WARNING
- This is not a function error of control module Y3/8n4 (Fully integrated transmission control (VGS) control unit) and does not justify
replacement.
Possible cause for the entry of this event code
- Operational fault of component A1 (Instrument cluster)
Possible measures
- Read out fault memory of control unit A1 (Instrument cluster).
- Process displayed fault codes in control module A1 (Instrument cluster).
End of test
EC424
One or more signals sent from control unit N22 (AAC [KLA] control and operating unit) via the CAN bus is implausible.
Possible cause:
- N22 (AAC [KLA] control and operating unit)
Affected functions:
- CAN Communication
- Automatic transmission Function

Part 1
No CAN message was received from control unit N80 (SCM [MRM] control unit).
Possible cause:
- Check the CAN communication with control unit N80 (Steering column module).
- Engine compartment CAN databus
Affected functions:
- CAN Communication
- Automatic transmission Function
-------------------------------------------------
Test 1: Engine compartment CAN test
Test 2: Check the CAN communication with control unit N80 (Steering column module).
