Workshop Hints: Diagnosis
All inputs/outputs that are part of the Power Module can be diagnosed by Test Modules or status checked by the Control Unit Functions of the Diagnosis Program. The outputs can also be activated by Component Activation and the power consumption displayed.
The Diagnosis Program is based on the E46 concept.
All electronic fuses and the electronic battery master switch are monitored for short circuits/circuit breaks. In the event of a fault, an appropriate entry is made in the PM's fault memory and, if appropriate, a check control message initiated.
