Power management: Undervoltage

Fault description
The diagnostic function monitors the electrical system
voltage at the DME/DDE with the engine running.

Condition for fault identification
Test condition:
The fault is recognized when the onboard electrical system's
voltage falls below 9 V.
Potential problem source(s):
- Defective battery
- Defective voltage regulator
- Defect in wiring harness (power supply wiring to
DME/DDE)
- DME/DDE voltage measurement defective
Terminal condition: none
Voltage condition:
- Electrical system voltage less than 9 V
Temperature condition:
- None
Time condition:
- None
Other conditions:
- Engine ON

Condition for fault memory entry
The diagnostic fault code is logged when the fault remains
present for longer than 1 min.

Action in service
- Use battery tester to check battery condition
- Check battery for damage (electrolyte loss, deformation,
?), replace as indicated
- Check alternator, replace as indicated
- Check power-supply voltage to DME/DDE,
- Determine whether internal ECU errors are logged in the
DME/DDE.
- Replace DME
