Door Ajar Switch Signal | 1 | 2 | 2 | -- |
Door Jamb Switch Ground | -- | 2 | 2 | -- |
1. Door Ajar Indicator Always Illuminated. 2. Door Ajar Indicator Inoperative. |
The body control module (BCM) provides voltage to each door jamb switch via the door ajar switch signal circuit. The door lamb switches are permanently grounded. The door ajar switches are normally open when the door is fully closed. When a door is opened, the door ajar switch contacts close providing a path to ground. The driver information center (DIC), illuminates the DOOR AJAR indicator when the BCM detects that one of the doors is open. The instrument panel cluster (IPC) receives a serial data message from the BCM indicating the door ajar status. If this message is displayed and the vehicle speed is greater than 5 km/h (3 mph), a chime will sound.

⇒ | If the parameter does not change, refer to Passenger Door Ajar Malfunction. |
⇒ | If greater than the specified range, test the ground circuit for an open/high resistance. |
⇒ | If not the specified value, test the signal circuit terminal A for a short to ground. If the circuit tests normal, replace the BCM. |
⇒ | If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM. |
⇒ | If greater than the specified range, test the ground circuit for an open/high resistance. |
⇒ | If not the specified value, test the signal circuit terminal A for a short to ground. If the circuit tests normal, replace the BCM. |
⇒ | If not the specified value, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace the BCM. |

The body control module (BCM) provides voltage to each door latch via the door ajar switch signal circuit. The door latches are permanently grounded. The door ajar switches are normally open when the door is fully closed. When a door is opened, the door ajar switch contacts close providing a path to ground.
