Pinpoint Test E: The Remote Start Is Inoperative

WARNING: This page is about a different car, the 2013 Ford F-150. 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? 
    1. Yes  : GO to E2.
    2. No  : REFER to HANDLES, LOCKS, LATCHES AND ENTRY SYSTEMS to DIAGNOSE and REPAIR the Remote Keyless Entry (RKE) system.
  2. E2 CHECK THE VEHICLE STARTING 
    • Attempt to start the vehicle.
    • Did the vehicle start? 
    1. Yes  : GO to E3.
    2. 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? 
    1. Yes  : CARRY OUT a self test of the PCM. DIAGNOSE and REPAIR any present DTCs. REFER to ELECTRONIC ENGINE CONTROLS or ENGINE CONTROLS - POWERTRAIN DTC CHARTS & DESCRIPTIONS (EXCEPT DIESEL & HYBRID) (SECTION 4) .
    2. No  : GO to E4.
  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? 
    1. Yes  : For BCM DTCs C113A:11 or C113A:15, GO to PINPOINT TEST C .

      For BCM DTC B1305:01, REFER to ANTI-THEFT SYSTEM - PERIMETER .

      For TPM DTCs U0140:87 or U0422:68, REFER to WHEELS & TIRES .

      For all other DTCs, REFER to MULTIFUNCTION ELECTRONIC MODULES .

    2. No  : GO to E5.
  5. E5 CONFIRM THE REMOTE START FUNCTION IS ENABLED 
    1. Yes  : GO to E6.
    2. 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? 
    1. Yes  : GO to E7.
    2. No  : INSTALL and PROGRAM a new IKT. REFER to ANTI-THEFT SYSTEM - PASSIVE ANTI-THEFT SYSTEM (PATS) . TEST the system for normal operation.
  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 11 volts? 
    1. Yes  : GO to E8.
    2. No  : VERIFY BCM fuse 18 (10A) is OK. If OK, REPAIR circuit CE436 (VT/OG) for an open. If not OK, REFER to OEM ELECTRICAL WIRING DIAGRAM INTRODUCTION for the appropriate System Wiring Diagrams 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? 
    1. Yes  : INSTALL a new PCM. REFER to ELECTRONIC ENGINE CONTROLS . TEST the system for normal operation.
    2. No  : CARRY OUT the required precondition as necessary. TEST the system for normal operation.
