CHECK THE (P669) DRIVER MIRROR SENSOR SUPPLY CIRCUIT OR THE (P666) PASSENGER MIRROR
SENSOR SUPPLY CIRCUIT FOR A SHORT TO GROUND
For the Driver Memory Mirror System, proceed as follows:
•
Turn the ignition off.
•
Disconnect the Driver Memory Mirror Module C1 connector.
•
Measure the resistance between ground and the (P669) Driver
Mirror Sensor Supply circuit in the Driver Memory Mirror Module
C1 connector.
For the Passenger Memory Mirror System, proceed as follows:
•
Turn the ignition off.
•
Disconnect the Passenger Memory Mirror Module connector.
•
