Right Door Lock Switch Failure

NAME OF CODE
Right Door Lock Switch Failure

WHEN MONITORED
Anytime battery voltage is above 10 volts and BCM is awake.

SET CONDITION
The BCM senses a voltage of 3.0 volts (+/-250mV) on the RF door switch MUX circuit for longer than 8 seconds.

THEORY OF OPERATION
The BCM interfaces with the power coor lock, unlock, arm and disarm switches via a single wire circuit (Door Switch MUX) for each door zone. Each zone functions independently of each other. Each switch inside the door has a unique resistance value which when activated sends a voltage level to the BCM. The BCM will interpret the different levels and perform the desired function.

POSSIBLE CAUSES
- Shorted right front door lock switch
- Body control module
