Pinpoint Test O : The RKE (Remote Keyless Entry) Transmitter Is Inoperative

  1. Normal Operation and Fault Conditions 

    REFER to: Handles, Locks, Latches and Entry Systems - Overview .

    DTC Fault Trigger Conditions 

    DTC Description Fault Trigger Condition
    BCM B10AB:00 Remote Keyless Entry Synchronization: No Sub Type Information Sets when the BCM detects the rolling counter received from a RKE transmitter is out of synchronization with the rolling counter stored in the module.
    BCM B1218:00 Transmitter Identification Code: No Sub Type Information Sets when the BCM detects and invalid Transmitter Identification Code (TIC).

    Possible Sources 

    • Key/key fob battery
    • Key/key fob
    • Key/key fob button pressed a substantial amount of times while outside the range of the vehicle
    • Key/key fob programming
    • Network concern

    Visual Inspection and Pre-checks 

    • Inspect the key/key fob for damage.
    • Check for aftermarket keys/key/fobs.

  2. NOTE: All customer keys/key fobs need to be present when diagnosing the RKE system.
  3. NOTE: Using a diagnostic scan tool to compare the BCM TIC_xx_BCM (Programmed Transmitter ID Code (TIC) Value x) PID to the RTM RTM Lst_Xm_ID_Cd (Last Received Transmitter ID Code (TIC)) PID can be used to verify if a key in question is programmed to the vehicle..

  4. O1 CHECK FOR THE CORRECT KEYS/KEY FOBS

    • Verify all keys/key fobs present are the correct type for the vehicle. Refer to the PATS Job Aid in the Service Tips tab on the Professional Technician Society (PTS) web page or the parts catalog.

    Are the correct keys present? 

    Yes  For vehicles equipped with standard PATS keys (fob concern), GO to  O5 For vehicles equipped with IKT keys, GO to  O2 For vehicles equipped with push button start, GO to  O4
    No  The system cannot be tested without the correct keys/key fobs. INFORM the customer that all of the correct keys/key fobs must be present to proceed with diagnosis of the system.

  5. O2 CHECK IF THE KEYS START THE VEHICLE (VEHICLES NOT EQUIPPED WITH PUSH BUTTON START)

    • Place the first key in the ignition lock cylinder and attempt to start the vehicle.

    • Ignition OFF.

    • Place the second key in the ignition lock cylinder and attempt to start the vehicle.

    Do both keys start the vehicle? 

    Yes  GO to  O3
    No  REFER to: Passive Anti-Theft System (PATS) .

  6. O3 CHECK THE BCM (BODY CONTROL MODULE) UNLIMITED KEY MODE

    NOTE: When the BCM is set to Unlimited Key mode, the IKT keys still start the vehicle but the RKE functionality is inoperative. The BCM only recognizes the first 2 keys reprogrammed for RKE functionality after it is set to Unlimited Key mode.

    • Ignition ON.

    • NOTE: Unlimited Key mode is used when more than 8 keys are required to be programmed to the vehicle. This mode should only be used for Fleet vehicle purposes.

      Using a diagnostic scan tool, access the security feature and determine if the BCM is in Unlimited Key mode. REFER to: Anti-Theft Key Programming - Scan Tool .

    Is the BCM Unlimited Key mode enabled? 

    Yes  If this is the desired mode, ERASE and PROGRAM the keys. REFER to: Anti-Theft Key Programming - Scan Tool . If this is not the desired mode, DISABLE the Unlimited Key mode. All IKT keys (up to 4) programmed prior to the BCM Unlimited Key mode being enabled have the RKE function restored.
    No  GO to  O5

  7. O4 CHECK IF THE KEYS START THE VEHICLE (VEHICLES EQUIPPED WITH PUSH BUTTON START)

    • Ignition OFF.

    • Place the second key in the backup starting location and attempt to start the vehicle.

    Do both keys start the vehicle? 

    Yes  GO to  O5
    No  REFER to: Passive Anti-Theft System (PATS) .

  8. O5 CHECK FOR REDUCED RANGE

    NOTE: Make sure the vehicle is in an open area with no other large metal objects near, such as other vehicles or steel buildings.

    NOTE: If the RKE functions when near the vehicle, but not at approximately 30m (98 ft), a poor range concern is present.

    • Check all keys/key fobs for normal range performance (approximately 30m (98 ft)).

    Does any key experience a poor range concern? 

    Yes  GO to Pinpoint Test Q 
    No  GO to  O6

  9. O6 CHECK THE RKE (REMOTE KEYLESS ENTRY) FUNCTIONALITY OF THE KEYS/KEY FOBS

    • Press each RKE button on a key/key fob. Repeat this step on a second key/key fob.

    Are all the RKE functions inoperative from both keys/key fobs? 

    Yes  GO to  O17
    No  GO to  O7

  10. O7 CHECK THE RKE (REMOTE KEYLESS ENTRY) FUNCTIONALITY OF THE SUSPECT KEY/KEY FOB

    • Press each RKE button (twice for the liftgate latch unlock) on the suspect key/key fob.

    Does any RKE function operate? 

    Yes  GO to Pinpoint Test P 
    No  GO to  O8

  11. O8 CHECK THE NO (TIC) OUT OF SYNC (TIC-NONE_OOS) PID (PARAMETER IDENTIFICATION)

    • Ignition ON.

    • Using a diagnostic scan tool, view the BCM Parameter Identifications (PIDs).

    • Using a diagnostic scan tool, monitor the BCMPID TIC-NONE_OOS.

    Does the PID indicate On? 

    Yes  GO to  O13
    No  For vehicles equipped with standard PATS keys (fob concern) GO to  O9 For vehicles equipped with IKT keys, GO to  O10 For vehicles equipped with push button start, GO to  O11

  12. O9 RESYNCHRONIZE THE INOPERATIVE KEY BY CYCLING THE IGNITION

    • Insert the suspect key into the ignition lock cylinder.

    • Ignition ON.

    • Wait 10 seconds.

    • Ignition OFF.

    • Remove the suspect key from the ignition lock cylinder and check the RKE transmitter operation.

    Does the suspect key operate correctly now? 

    Yes  The system is OK. The concern was caused by a key out of synchronization.
    No  GO to  O12

  13. O10 RESYNCHRONIZE THE INOPERATIVE KEY FOB

    • Within 1 second, press any button on the suspect key fob 3 times consecutively.
