Defect Code 03

Defect Code 03:

Explanation:

Defect on the connection link (interface) to the DME (ignition angle adjustment)

Possible cause:

Short or break on the wire to the DME control unit

Troubleshooting:

Switch off ignition and detach control unit connector

Check ZWV wire from ABS/ASC+T Pin 9 to the DME and repair if necessary

Connect control unit and switch on ignition.

Read out ignition angle (dynamic) by way of the DME diagnostic program <-D-> 200 status monitoring for both DME control units. Simulate ASC+T control mode; the ignition angle must be set towards retard.

If the ignition timing is not adjusted, there is a defect either in the ABS/ASC+T or in a DME control unit.
