Passive Transmitter Malfunction

Place the keyless entry transmitter on the J 43241  and approach the vehicle. Operate the release handle/touch pad. Verify the J 43241  sounds a tone. See Special Tools .

• If the tone does not sound, replace the transmitter battery and retest with the J 43241  . If the condition continues after battery replacement, replace the keyless entry transmitter. See Special Tools .

Antenna Circuit Malfunction

1. Ignition OFF, disconnect the harness connector at the inoperative T10 handle keyless entry antenna.
2. Ignition ON, test for less than 1 V between the signal circuit terminal 1 and ground.
   • If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the K84 keyless entry control module.
3. Ignition OFF, install a DMM between the signal circuit terminal 1 and ground. Set the DMM to capture DC voltage using the MIN MAX function.
4. Lock the vehicle doors using the keyless entry transmitter.
5. Activate the antenna by pulling/pressing the exterior door handle/touch pad. Verify the MAX voltage captured by the DMM is greater than .5 V.
   • If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K84 keyless entry control module.
6. Install a DMM between the signal circuit terminal 1 and the low reference circuit terminal 2. Set the DMM to capture DC voltage using the MIN MAX function.
7. Lock the vehicle doors using the keyless entry transmitter.
8. Activate the antenna by pulling/pressing the exterior door handle/touch pad. Verify the MAX voltage captured by the DMM is greater than.5 V.
   • If less than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K84 keyless entry control module.
9. If all circuits test normal, replace the T10 handle keyless entry antenna.
