Normal Operation
The driver door module (DDM) sends voltage to the antenna on circuit 2308 (RD/WH) and provides ground on circuit 2307 (BK/WH). The antenna receives signals from the RKE transmitter and sends the signals to the DDM on circuits 2305 (VT/LB), 2306 (GY/RD) and 2309 (LB/BK). The DDM carries out the function requested by the RKE transmitter.

DTC B1148 - is a continuous DTC that sets when the DDM detects that RF_RECVR_PWR circuit 2308 (RD/WH) is short to ground.

DTC B1149 - is a continuous DTC that sets when the DDM detects that RF_RECUR_ENABLE circuit 2305 (VT/LB) is short to voltage.

DTC B1150 - is a continuous DTC that sets when the DDM detects that RF_RECUR_ENABLE circuit 2305 (VT/LB) is short to ground.

DTC B1151 - is a continuous DTC that sets when the DDM detects that RF_ASK/FSK_SEL circuit 2306 (GY/RD) is short to ground.

DTC B1152 - is a continuous DTC that sets when the DDM detects that RF_ASK/FSK_SEL circuit 2306 (GY/RD) is short to voltage.

- Circuit 2307 (BK/WH) open or short to voltage
- Circuit 2308 (RD/WH) open or short to ground
- Circuit 2309 (LB/BK) open, short to ground or voltage
- Antenna
- DDM
