Pinpoint Test G: The RKE Transmitter Is Inoperative

NOTE: Aftermarket or dealer-installed systems may adversely affect the RKE  system operation. These systems should be disconnected before diagnosing any RKE  concerns.
  1. G1 CHECK FOR THE CORRECT RKE TRANSMITTERS 
    • Check that the correct IKTs  are used with the vehicle. Compare the IKTs  with the one shown in Handles, Locks, Latches and Entry Systems  .
    • Are all the correct IKTs present? 
    • Yes:  GO to G2  .
    • No:  The system cannot be tested without the correct IKTs  . INFORM the customer that the correct IKTs  must be present to proceed with diagnosis of the system.
  2. G2 CHECK THE RECORDED SJB AND IPC DTCs FROM THE SELF-TEST 
    • Check the recorded results from the SJB  and IPC  self-test.
    • Is DTC B2425 or DTC B1218:51 recorded? 
    • Yes:  For DTC B2425, GO to G3  .

      For DTC B1218:51, GO to PINPOINT TEST H .

    • No:  GO to  G4.
  3. G3 RESYNCHRONIZE THE INOPERATIVE IKT 
    • Ignition OFF.
    • Ignition ON.
    • Leave the IKT  key in the ON position for a minimum of 6 seconds.
    • Ignition OFF.
    • Press any button on the IKT  .
    • Does the IKT operate? 
    • Yes:  The system is OK. CLEAR the DTCs. REPEAT the self-test.
    • No:  GO to G4  .
  4. G4 MAKE SURE THE RKE TRANSMITTER SIGNAL IS BEING RECEIVED 
    • Enter the following diagnostic mode on the scan tool: SJB  DataLogger.
    • Press lock and unlock on the IKT  while observing the SJB  PIDs (TIC_LAST) and (TNSMT_CMD).
    • Does the TIC and RKE command show up on the scan tool screen when a button is pressed? 
    • Yes:  GO to G5  .
    • No:  GO to  G6.
  5. G5 CHECK IF THE RKE TRANSMITTERS ARE PROGRAMMED 
    • Enter the following diagnostic mode on the scan tool: SJB  DataLogger.
    • Press a button on the IKT  and compare the SJB  PID (TIC_LAST) with the PIDs (TIC_1, 2, 3, 4, 7, 8, 9, or 10).
    • Does the TIC displayed match any of the TICs stored in memory? 
    • Yes:  GO to  G8.
    • No:  PROGRAM the inoperative IKT  individually or PROGRAM all the IKTs  . REFER to ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS) for the programming procedures. If all the IKTs  are to be programmed, INFORM the customer that any IKTs not present need to be programmed. TEST the system for normal operation.
  6. G6 CHECK THE IKT BATTERY 
    • Using a thin coin, open the IKT  .
    • 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 IKT  battery and measure the voltage.
    • Is the voltage greater than 2.5 volts? 
    • Yes:  GO to G7  .
    • No:  INSTALL a new battery (make sure the battery is seated correctly). DO NOT reprogram the IKT  (weak or dead batteries do not erase TICs  from memory). TEST the system for normal operation.
  7. G7 CHECK FOR NORMAL OPERATION WITH A KNOWN GOOD IKT 
    • Enter the following diagnostic mode on the scan tool: SJB  DataLogger.
    • Use the customer's second IKT  , or a known good RKE  transmitter that is correct for the vehicle, press a button on the IKT  while observing the SJB  PID (TIC_LAST).
    • Does the TIC show up on the scan tool when a button is pressed? 
    • Yes:  REPLACE the inoperative IKT  and PROGRAM the inoperative IKT  individually or PROGRAM all the IKTs  . REFER to ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS) for the programming procedures. If all the IKTs  are to be programmed, INFORM the customer that any IKTs  not present need to be programmed. TEST the system for normal operation.
    • No:  GO to G8  .
  8. G8 CHECK FOR CORRECT SJB OPERATION 
    • Disconnect all the SJB  connectors.
    • Check for:
      • corrosion
      • damaged pins
      • pushed-out pins
    • Connect all the SJB  connectors and make sure they seat correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 
    • Yes:  INSTALL a new SJB  . REFER to MULTIFUNCTION ELECTRONIC MODULES . TEST the system for normal operation.
    • No:  The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
