Pinpoint Test D: The Doors Do Not Lock/Unlock Using The Remote Keyless Entry (RKE) Transmitter
Normal Operation
Remote locking and unlocking of the doors is accomplished by the Smart Junction Box (SJB) receiving a command message from the RKE transmitter. The SJB processes the command and provides voltage and ground to the door lock actuators.
- DTC B1139 (Invalid Transmitter Identification Code) - a continuous DTC that sets when the SJB detects that an RKE transmitter is sending an invalid transmitter identification code.
This pinpoint test is intended to diagnose the following:
- RKE transmitter battery
- RKE transmitter programming
- RKE transmitter
- Aftermarket systems
- High power devices
- TV/radio transmission towers
- SJB
PINPOINT TEST D: THE DOORS DO NOT LOCK/UNLOCK USING THE RKE TRANSMITTER
NOTE: All RKE transmitters must be present to begin diagnosis of the RKE system.
NOTE: Aftermarket or dealer-installed systems may adversely affect the RKE system operation. These systems should be disconnected before diagnosing any RKE concerns.
-------------------------------------------------
D1 CHECK FOR THE CORRECT RKE TRANSMITTERS
- Check that the correct RKE transmitters are used with the vehicle. Compare the RKE transmitters with the one shown in Handles, Locks, Latches and Entry Systems Description and Operation in the Description and Operation.
- Are the correct RKE transmitters present?
Yes
GO to D2.
No
The system cannot be tested without the correct RKE transmitters. INFORM the customer that the correct RKE transmitters need to be present to proceed with diagnosis of the system.
-------------------------------------------------
D2 CHECK THE OPERATION OF THE RKE TRANSMITTER WITH THE KEY IN THE OFF POSITION
- Ignition OFF.
- Check the operation of the RKE transmitter.
- Does the system operate correctly now?
Yes
The system is operating as designed. INFORM the customer of the correct vehicle operation.
No
GO to D3.
-------------------------------------------------
D3 CHECK THE POWER DOOR LOCK SYSTEM FOR CORRECT OPERATION
- Verify the door lock/unlock operation by actuating the driver door lock control switch.
- Do all the doors lock and unlock correctly?
Yes
GO to D4.
No
GO to Pinpoint Test B. Pinpoint Test B: All Door Locks Are Inoperative
-------------------------------------------------
D4 CHECK FOR THE COMPLETE FUNCTIONALITY OF THE RKE TRANSMITTER(S)
- Check all the RKE transmitter buttons on each transmitter for correct operation.
- Does the PANIC button operate correctly?
Yes
REPLACE the inoperative RKE transmitter. PROGRAM the new RKE transmitter individually using a scan tool or PROGRAM all RKE transmitters using the manual key cycle method. REFER to Remote Keyless Entry (RKE) Transmitter Programming Testing and Inspection. TEST the system for normal operation.
No
GO to D5.
-------------------------------------------------
D5 MAKE SURE THE RKE TRANSMITTER SIGNAL IS BEING RECEIVED
NOTE: Using the scan tool, select "Toolbox", "Body", then "Security" to access the remote keyless entry tests.
- Enter the following diagnostic mode on the scan tool: Remote Keyless Entry.
- Monitor the RKE Transmitter Identification Code (TIC) and the RKE command through the scan tool menus.
- Verify the RKE transmitter signal is being received. Using a scan tool, press a button on the RKE transmitter while observing the scan tool.
- Does the TIC and RKE command show up on the scan tool screen when a button is pressed?
Yes
GO to D6.
No
GO to D7.
-------------------------------------------------
D6 CHECK IF THE RKE TRANSMITTERS ARE PROGRAMMED
- Enter the following diagnostic mode on the scan tool: Remote Keyless Entry.
- Monitor the RKE transmitter TIC data through the scan tool menus.
- Verify the RKE transmitters are programmed to the vehicle.
- Does the TIC displayed under the current RKE transmitter match any of the TICs stored in memory?
Yes
GO to D8.
No
PROGRAM the inoperative RKE transmitter individually using a scan tool or PROGRAM all RKE transmitters using the manual key cycle method. REFER to Remote Keyless Entry (RKE) Transmitter Programming Testing and Inspection. INFORM the customer that any RKE transmitters not present need to be programmed. CLEAR the DTCs. REPEAT the self-test.
-------------------------------------------------
D7 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 D9.
No
INSTALL a new battery (be sure the battery is seated correctly). DO NOT reprogram the RKE transmitters (damaged or dead batteries do not erase TICs from memory). CLEAR the DTCs. TEST the system for normal operation.
-------------------------------------------------
D8 CHECK IF THE RKE TRANSMITTER IS OUT OF SYNCHRONIZATION WITH THE SJB
- The vehicle must be electronically unlocked prior to using any scan tools (through the RKE transmitter or the door lock control switch).
- Retrieve continuous DTCs through the scan tool.
- Is continuous DTC B2425 stored in the SJB?
Yes
GO to Pinpoint Test E. Pinpoint Test E: The Remote Keyless Entry (RKE) Transmitter Is Out Of Synchronization
No
GO to D9.
-------------------------------------------------
D9 CHECK FOR NORMAL OPERATION WITH A SECOND RKE TRANSMITTER
- Enter the following diagnostic mode on the scan tool: Remote Keyless Entry.
- Monitor the RKE transmitter TIC/DATA through the scan tool menus.
- Using the customer's second RKE transmitter, or a known good RKE transmitter that is correct for the vehicle, verify the RKE transmitter signal is being received by the SJB.
- Does the TIC show up on the scan tool when a button is pressed on the RKE transmitter?
Yes
REPLACE the inoperative RKE transmitter. PROGRAM the new RKE transmitter individually using a scan tool or PROGRAM all RKE transmitters using the manual key cycle method. REFER to Remote Keyless Entry (RKE) Transmitter Programming Testing and Inspection. TEST the system for normal operation.
No
GO to D10.
-------------------------------------------------
D10 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 Body Control Systems. 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.
