Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the console passive antenna.

2. Place a valid keyless entry transmitter in the pocket located in the center console. This will allow the console active antenna to authenticate

the keyless entry transmitter and allow the ignition to be turned on.

3. Ignition ON, verify a test lamp does not illuminate between the signal circuit terminal A and ground.

瀚慖f the test lamp illuminates, test the signal circuit for a short to voltage. If the circuit tests normal, replace the RCDLR.

4. Connect a DMM, set to capture AC voltage using the MIN MAX function, between the signal circuit terminal A and the low reference circuit

terminal B.

5. Attempt to start the vehicle. Verify the DMM captured an AC voltage signal.

瀚慖f an AC voltage was not captured, test the signal circuit and the low reference circuit for a short to ground or an open/high resistance. If

the circuits test normal, replace the RCDLR.

6. If all circuits test normal, test or replace the console passive antenna.
