Fault text
Power management: Ripple in system voltage too high

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 logged in the control module's fault memory
when the electrical system voltage is less than 8.5 V or
higher than 18 V.
Potential problem source(s):
- Battery not connected correctly (loose contact).
- 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 8.5 V
- Electrical system voltage greater than 18 V
Temperature condition:
- None
Time condition:
- None
Other conditions:
- Engine ON

Condition for fault memory entry
This fault is logged in the control module's fault memory
immediately.

Action in service
- Check screws on battery terminals
- Check DME/DDE power-supply voltage
- Determine whether internal control module faults have
been logged in the DME/DDE.

Fault effect and breakdown warning
Breakdown notice:
None
Possible apparent symptoms:
- Flickering lights
- Functional failure (loss of functionality)
- In extreme cases engine fails to operate owing to
undervoltage.

Driver information
Warning light:
- ECE emissions warning lamp: off
- ECE electronic engine power reduction: off
- CC message: on
- US emissions warning lamp: off
- US electronic engine power reduction: off
- CC message: on
