ED504
One or more signals sent from control unit N80 (Steering column module) via the CAN bus is implausible.
Possible cause:
- N80 (Steering column module)
Affected functions:
- CAN Communication
- Automatic transmission Function
-------------------------------------------------
Test 1: Fault in CAN communication with control unit N80 (Steering column module).
1. Fault in CAN communication with control unit N80 (Steering column module).
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 N80 (Steering column module)
Possible measures
- Read out fault memory of control unit N80 (Steering column module).
- Process displayed fault codes in control module N80 (Steering column module).
End of test
EP0A7C
The control unit is overheated.
Test 1: Check component M3 (Fuel pump).
Test 2: Test control signal for component Fuel pump.
Test 3: Signal wire PWM signal Fuel pump
Test 4: Check power supply at control unit N118 (Fuel pump control module).
Test 5: Possible cause:
- M3 (Fuel pump)
- N118 (Fuel pump control module)
Affected functions:
- Engine diagnosis
- Fuel system
1. Check component M3 (Fuel pump).
Test 1.1: Test fuel pressure and internal leaks of fuel system.
Test 1.2: Test delivery of component M3 (Fuel pump).
Test 1.3: Check power consumption of component M3 (Fuel pump) using actual value.
Test 1.4: Test the cables from component N118/3 (Left fuel pump control unit) to component M3 (Fuel pump) with the plug connection M3x1
(Fuel pump connector) between the two.
1.1. Test fuel pressure and internal leaks of fuel system.
Warning!Communication with ECU required.
