Fault Information


Fault Code Description
The control units exchange information via the bus.
An "interface error" (invalid signal) is stored when urgently required signals are only received in the form of a substitute value or as an "invalid signal".
The fault is logged when the partner control unit (=interface) transmits a substitute value or a value designated as invalid instead of the required information. In this case, a fault code should also be stored in the corresponding partner control unit.

Fault Code Conditions
General Conditions Supply voltage between 9 and 16 volts.
Terminal Condition Terminal 15
on
Terminal Condition PWF status: Driving

Terminal Condition PWF status: Residing

Driving Conditions Note: The designations of terminal status or PWF status apply according to the vehicle electrical system of the vehicle.

Fault Time Condition
The fault code is entered after starting the control unit after a maximum of 10 seconds.
Service Plan
Work through all stored faults of the partner control unit according to the test plan.
Especially faults that affect the vicinity of the partner control unit (e.g. connected sensor system).
These types of faults are consequential faults.
If there are no further test modules in the test plan then no further repair measures are required.
