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 - sets when the radio frequency power output circuit is shorted to ground.

DTC B1149 - sets when the radio frequency enable output circuit is shorted to voltage.

DTC B1150 - sets when the radio frequency enable output circuit is shorted to ground.

DTC B1151 - sets when the radio frequency AM/FM signal key select output circuit is shorted to ground.

Possible Causes
- Circuit 2305 (VT/LB) open, short to ground or voltage
- Circuit 2306 (GY/RD) open, short to ground or 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
