Pinpoint Test E: The Remote Start Is Inoperative

WARNING: This page is about a different car, the 2012 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
  1. E1 CHECK THE OPERATION OF THE IKT 
    • Press all buttons on the IKT and check for the correct operation.
    • Is the remote start the only function that is inoperative? 
  2. E2 CHECK THE VEHICLE STARTING 
    • Attempt to start the vehicle.
    • Did the vehicle start? 
      • YES  : GO to E3.
      • No  : This is not a remote start issue. GO to Symptom Chart  to diagnose the no crank condition.
  3. E3 CHECK FOR ILLUMINATED ENGINE WARNING LAMPS 
    • With the engine running check the instrument cluster for illuminated warning lamps.
    • Are any engine warning lamps illuminated? 
  4. E4 RETRIEVE BCM AND TPM DTCs 
    • Enter the following diagnostic mode on the scan tool: BCM - Self-Test.
    • Enter the following diagnostic mode on the scan tool: TPM - Self-Test.
    • Are any DTCs present? 
  5. E5 CONFIRM THE REMOTE START FUNCTION IS ENABLED 
    • Ignition ON.
    • Check the message center and confirm the remote start function is enabled. Refer to the Owner's Literature or INSTRUMENTATION, MESSAGE CENTER, AND WARNING CHIMES .
    • Is the remote start function enabled? 
      • YES  : GO to E6.
      • No  : ENABLE the remote start function. TEST the system for normal operation.
  6. E6 CHECK THE BCM LAST RECEIVED RKE TRANSMITTER BUTTON PRESS (LST_RKE_xMTR) TRANSMITTER PID 
    • Enter the following diagnostic mode on the scan tool: DataLogger - BCM.
    • Press the remote start button on the IKT and note the PID status.
    • Does the selected PID indicate the remote start button was the last button pressed? 
  7. E7 CHECK THE PCM WAKE UP CIRCUIT 
    • Ignition OFF.
    • Disconnect: PCM C175B (5.0L and 6.2L), C1381B (3.7L) or C1551B (3.5L).
    • Ignition ON.
    • Measure the voltage between the PCM C1551B-28 (3.5L), circuit CE436 (VT/OG), harness side and ground.

    • Is the voltage greater than 10 volts? 
      • YES  : GO to E8.
      • No  : VERIFY BCM fuse 18 (10A) is OK. If OK, REPAIR circuit CE436 (VT/OG) for an open. If not OK, REFER to the Wiring Diagrams information to identify the possible causes of the circuit short. CLEAR the DTCs. REPEAT the self-test. TEST the system for normal operation.
  8. E8 CHECK THE REMOTE START PRECONDITIONS FOR CORRECT OPERATION 
    NOTE: The Body Control Module (BCM) acknowledges the remote start request and that all preconditions have been met by providing 2 short flashes of the turn indicators and a system complete chirp.
    • Make sure that the following preconditions for remote start have been met:
      • Hood is closed with no DTC present.
      • Ignition must be off
      • Vehicle must be in PARK.
      • Remote start feature is configured ON.
      • Number of remote start events does not exceed allowed time (2 events in a 1 hour duration).
      • Attempt to carry out a remote start.
    • Is the remote start system still inoperative? 
      • YES  : INSTALL a new PCM. REFER to ELECTRONIC ENGINE CONTROLS . TEST the system for normal operation.
      • No  : CARRY OUT the required precondition as necessary. TEST the system for normal operation.
