Pinpoint Test Q: The RKE Transmitter Is Inoperative (Without IA)

NOTE: All the customer RKE transmitters need to be present when diagnosing the RKE system.

Q1 CHECK ALL THE BUTTONS ON THE SUSPECT RKE TRANSMITTER
- Press each button on the RKE transmitter (twice for the liftgate release).
- Do any of the functions operate?
- Yes : GO to PINPOINT TEST S .
- No : GO to Q2.
Q2 CHECK FOR THE CORRECT RKE 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 B1D21:62 FROM THE BCM SELF-TEST
- Using a scan tool, perform the BCM self-test.
- Is DTC B1D21:62 present?
- Yes : If only one transmitter is present, GO to Q4.
  If more than one transmitter is present, GO to Q5.
- No : GO to Q6.
Q4 RESYNCHRONIZE THE RKE 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 an RKE transmitter out of synchronization.
- No : GO to Q6.
Q5 RESYNCHRONIZE THE INOPERATIVE RKE 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 an RKE transmitter out of synchronization.
- No : GO to Q6.
Q6 CHECK THE RKE TRANSMITTER BATTERY
- Using a thin coin, open the RKE transmitter.
- 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 TICs from memory).
Q7 PROGRAM THE SUSPECT RKE TRANSMITTER
NOTE: 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 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. 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 IKT, ERASE and PROGRAM the keys. REFER to ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS), WITHOUT INTELLIGENT ACCESS (IA) .
  
  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 OPERATION
- Disconnect and inspect all the BCM connectors.
- Repair:
  - corrosion (install new connector or terminals - 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 On-Line Automotive Service Information System (OASIS) for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new BCM. REFER to MULTIFUNCTION ELECTRONIC MODULES .
- No : The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
