Pinpoint Test Q : The RKE (Remote Keyless Entry) Transmitter Is Inoperative (Without Push Button Start)
- Q1 CHECK ALL THE BUTTONS ON THE SUSPECT RKE (REMOTE KEYLESS ENTRY) TRANSMITTER
- Press each button on the RKE transmitter (twice for the liftgate).
Do any of the functions operate?
Yes GO to Pinpoint Test S No GO to Q2 - Q2 CHECK FOR THE CORRECT RKE (REMOTE KEYLESS ENTRY) TRANSMITTERS
- Check that the correct RKE transmitters are used with the vehicle.
Are the correct RKE transmitters present?
Yes GO to Q3 No The system cannot be tested without the correct RKE transmitters. INFORM the customer the correct RKE transmitters must be present to proceed with diagnosis of the system. - Q3 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) B1D21:62 FROM THE BCM (BODY CONTROL MODULE) SELF-TEST
- Ignition ON.
- Using a diagnostic scan tool, carry out the BCM self-test.
Is DTC B1D21:62 present?
Yes If only one transmitter is present, GO to Q4If more than one transmitter is present, GO to Q5 No GO to Q6 - Q4 RESYNCHRONIZE THE RKE (REMOTE KEYLESS ENTRY) TRANSMITTER
- Ignition OFF.
- Within close proximity of the vehicle, press any of the buttons 3 consecutive times within 30 seconds.
- Observe the vehicle for audible or visual feedback.
Does the RKE transmitter now function?
Yes The system is OK. The concern was cause by a RKE transmitter out of synchronization. No GO to Q6 - Q5 RESYNCHRONIZE THE INOPERATIVE RKE (REMOTE KEYLESS ENTRY) TRANSMITTER USING THE FUNCTIONING RKE (REMOTE KEYLESS ENTRY) TRANSMITTER
- Ignition OFF.
- Press any button on the functioning RKE transmitter and activate the locks or the liftgate release.
- Within 30 seconds of activating the locks or the liftgate release, press a button on the non-functioning RKE transmitter.
- Observe the vehicle for audible or visual feedback.
Does the suspect RKE transmitter now function?
Yes The system is OK. The concern was cause by a RKE transmitter out of synchronization. No GO to Q6 - Q6 CHECK THE RKE (REMOTE KEYLESS ENTRY) TRANSMITTER BATTERY
- Open the RKE transmitter. Refer to the Owner's Literature for the Integrated Keyhead Transmitter (IKT) battery replacement procedure.
- Do not clean off any grease from the battery terminals on the back surface of the circuit board.
- Verify the correct battery is used (CR2032).
- Remove the RKE transmitter battery and measure the voltage.
Is the voltage greater than 2.5 volts?
Yes GO to Q7 No INSTALL a new battery (make sure the battery is seated correctly). DO NOT reprogram the RKE transmitter (weak or dead batteries do not erase transmitter identification from memory). - Q7 PROGRAM THE SUSPECT RKE (REMOTE KEYLESS ENTRY) TRANSMITTERNOTE: Any RKE transmitter not present is erased from the BCM memory during the RKE transmitter programming procedure.
- Program the inoperative RKE transmitter. REFER to: Remote Keyless Entry (RKE) Transmitter Programming .
- Press the lock and then the unlock buttons on the suspect RKE transmitter.
Do the doors lock and then unlock?
Yes The system is OK. The concern was caused by an unprogrammed RKE transmitter. No GO to Q8 - Q8 PROGRAM A KNOWN GOOD RKE (REMOTE KEYLESS ENTRY) TRANSMITTERS (KEY FOB)NOTE: Any RKE transmitter not present is erased from the BCM memory during the RKE transmitter programming procedure.
- Program a known good RKE transmitter (key fob). REFER to: Remote Keyless Entry (RKE) Transmitter Programming .
- Press the lock and then the unlock buttons on the known good RKE transmitter.
Do the doors lock and then unlock?
Yes REPLACE the suspect RKE transmitter. If the suspect RKE transmitter is an Integrated Keyhead Transmitter (IKT), ERASE and PROGRAM the keys. REFER to: Erase All Keys and Key Programming . If the suspect RKE transmitter is a key fob, PROGRAM the RKE transmitter. REFER to: Remote Keyless Entry (RKE) Transmitter Programming . No GO to Q9 - Q9 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION
- Disconnect and inspect all BCM connectors.
- Repair:
- corrosion (install new connector or terminal - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect the BCM connectors. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
Yes CHECK OASIS for any applicable TSB. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no TSB addresses this concern, INSTALL a new BCM. REFER to: Body Control Module (BCM) . No The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
