Symptom:
DRIVER DOOR UNLOCK OUTPUT CIRCUIT SHORT TO GROUND
OR VOLTAGE
When Monitored and Set Condition:
DRIVER DOOR UNLOCK OUTPUT CIRCUIT SHORT TO GROUND OR VOLTAGE
When Monitored:
Whenever the instrument cluster is awake.
Set Condition:
The instrument cluster monitors the driver door unlock output circuit and
when it is shorted to ground or to voltage, this code will set. This code will only set when
the door locks are actuated.
