RKE Range To Short From All Transmitters

Possible Causes:

• DTC's Present
• RKE Antenna Circuit Open
• RKE Antenna Circuit Short To Ground
• RKE Module

Testing

1. With the DRBIII(R), read DTC's. Are there any Power Door Lock related codes present? If yes, see POWER DOOR LOCKS/RKE  for related problems. Perform BODY VERIFICATION TEST  . If no, go to next step.
2. Turn the ignition off. Disconnect the Body Control Module C2 connector. Measure the resistance of the RKE Antenna circuit between cavities 1 and '12 in the BCM C2 connector. Is the resistance below 2.0 ohms? If yes, go to next step. If no, repair the RKE Antenna circuit for an open. Perform BODY VERIFICATION TEST  .
3. Turn the ignition off. Disconnect the Body Control Module C2 connector. Measure the resistance between ground and the RKE Antenna circuit in the BCM C2 connector. Is the resistance below 1000.0 ohms? If yes, repair the RKE Antenna circuit for a short to ground. Perform BODY VERIFICATION TEST  . If no, go to next step.
4. If there are no possible causes remaining, replace the Remote Keyless Entry Module. Perform BODY VERIFICATION TEST  .
