Passenger Door Ajar (141)

The RH Front Door Module (RFDM) supplies ignition voltage to the RH front door jamb switch via circuit 746 (BLK/WHT). The RFDM monitors this circuit at connector C2 terminal B, if the RH front door is ajar/open the switch closes and circuit 746 (BLK/WHT) is grounded via circuit 451 (BLK/WHT). The RFDM detects this ground condition and sends a door ajar/open status (serial data) message via the Simple Data Interface (SBI) to the LFDM. The LFDM detects this door open/ajar message and sends a class 2 serial data message to the IPC requesting that this message is displayed. If the vehicle speed is greater than 4.8 km/h (3 mph) the IPC displays the message and request the radio via a class 2 message to activate a multiple medium chime.
