Passenger Door Ajar - 141

The Right Front Door Module (RFDM) supplies ignition voltage to the right front door jamb switch via circuit 746 (BLK/WHT). The RFDM monitors this circuit at connector C2 terminal B. If the right 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 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 requests the radio via a class 2 message to activate a multiple medium chime.
