- Rear Fog Lamp Switch Circuit Short to Ground

Diagnostic Fault Information

Circuit/System Description

The auxiliary body control module (XBCM) receives a momentary ground signal from the rear fog lamp switch when the switch is activated. The

rear fog lamps will remain illuminated until the switch is activated again or when the ignition key is cycled.

Conditions for Running the DTC

System voltage to the XBCM must be 9-16 V.

Diagnostic Fault Information

Circuit/System Description

The liftgate object sensors are pressure sensitive touch tapes located on either side of the upper inside edge of the liftgate panel. The two tape

switches are placed in series between the liftgate object sensor signal circuit and the liftgate object low reference circuit. Each object sensor has a

resistor as well as a switch. The resistors enable the liftgate module to perform diagnostic functions on the circuits. When both touch tape sensors

are not pressed, the 5 volt reference voltage supplied by the liftgate module passes through the resistors and the liftgate module detects

approximately 3.3 volts. Pressing a touch tape will cause the voltage to drop to approximately to 2.5 volts indicating an obstruction is present. If the
