Left Door Is Open

Left Door Open:

Door Ajar Circuit:

DESCRIPTION:

The BCM provides system voltage to the left door ajar circuit, and the left door ajar switch provides the single path to ground. The BCM supplies and internally monitors the voltage level of the circuit at pin 2B4. When the left door ajar circuit is open the BCM will detect system voltage, but if the left door ajar switch provides a path to ground (left door open), the BCM will detect the circuit has been grounded. Once the BCM has determined that all of the failure conditions have been met, it will send the "LEFT DOOR AJAR" message to the IPC. The BCM will also activate the slow paced chime on the chime module.

TEST CONDITIONS:

1. Code B334 is not set.
2. PCM UART data line is OK.

FAILURE CONDITIONS:

1. PRNDL is OK, (no code B127 set).
2. Engine is running.
3. Transmission not in Park or Neutral.
4. Left door ajar switch input is low.
5. Vehicle speed not over 5.0 mph.
6. Left door open failure code already set.
7. Left door ajar switch is closed.

ACTION TAKEN:

1. Display the "LEFT DOOR OPEN" message on the IPC.
2. Activate the slow chime.
