Normal Operating Mode
- The normal operation of the GEM can detect errors.
- An integral part of the normal GEM operation is the continuous diagnostic capability. Continuous diagnostics detects errors and changes the GEM control strategy.
- There is no warning light for the GEM; therefore, a DTC concern will direct the technician to the GEM.
- Examples of faults that may be detected during normal operation include:
- GEM continuous self-test.
- Output driver monitoring (open circuit/short to GND, short to power).
- Illogical combinations of input signals.
