Test N: All Remote Keyless Entry (RKE) Transmitters Are Inoperative

PINPOINT TEST N: ALL REMOTE KEYLESS ENTRY (RKE) TRANSMITTERS ARE INOPERATIVE

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 (Radio Frequency Power Output Circuit Short to Ground) - is a continuous DTC that sets when the DDM detects that RF_RECVR_PWR circuit 2308 (RD/WH) is short to ground.
- DTC B1149 (Radio Frequency Enable Output Circuit Short to Battery) - is a continuous DTC that sets when the DDM detects that RF_RECUR_ENABLE circuit 2305 (VT/LB) is short to voltage.
- DTC B1150 (Radio Frequency Enable Output Circuit Short to Ground) - is a continuous DTC that sets when the DDM detects that RF_RECUR_ENABLE circuit 2305 (VT/LB) is short to ground.
- DTC B1151 (Radio Frequency AM/FM Signal Key Select Output Circuit Short to Ground) - 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 (Radio Frequency AM/FM Signal Key Select Output Circuit Short to Battery) - is a continuous DTC that sets when the DDM detects that RF_ASK/FSK_SEL circuit 2306 (GY/RD) is short to voltage.
