For a complete wiring diagram Consult Diagrams/Electrical.

- When Monitored:
At all times.

- Set Condition:
Anytime the module senses voltage input less than 2.0 volts for over 10 seconds, this code will set.





1. TEST FOR INTERMITTENT CONDITION
With the scan tool, record and erase DTC's
Operate the driver power window and door locks several times if possible.
With the scan tool, read DTC's.
