Pinpoint Test E: The Remote Start Is Inoperative
WARNING: This page is about a different car, the 2014 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
- 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?
- Yes : GO to E2 .
- No : REFER to HANDLES, LOCKS, LATCHES AND ENTRY SYSTEMS to DIAGNOSE and REPAIR the Remote Keyless Entry (RKE) system.
- 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.
- 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?
- Yes : CARRY OUT a self test of the PCM . DIAGNOSE and REPAIR any present DTCs. REFER to ELECTRONIC ENGINE CONTROLS or ENGINE CONTROLS - INTRODUCTION (EXCEPT DIESEL & HYBRID) (SECTION 0) .
- No : GO to E4 .
- 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?
- Yes
: For BCM
DTCs C113A:11 or C113A:15, GO to PINPOINT TEST C .
For BCM DTC B1305:01, REFER to ANTI-THEFT - PERIMETER .
For TPM DTCs U0140:87 or U0422:68, REFER to WHEELS AND TIRES .
For all other DTCs, REFER to MULTIFUNCTION ELECTRONIC MODULES .
- No : GO to E5 .
- 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.
- E6 CHECK THE BCM LAST RECEIVED RKE TRANSMITTER BUTTON PRESS (LST_RKE_xMTR) TRANSMITTER PID
- Enter the following diagnostic mode on the scan tool: Data Logger - 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?
- Yes : GO to E7 .
- No : INSTALL and PROGRAM a new IKT . REFER to ANTI-THEFT - PASSIVE ANTI-THEFT SYSTEM (PATS) . TEST the system for normal operation.
- E7 CHECK THE PCM WAKE UP CIRCUIT
- Ignition OFF.
- Disconnect: PCM C1551B (3.5L) C175B (3.7L) or C1381B (5.0L and 6.2L).
- Ignition ON.
- Measure the voltage between the PCM C1551B-28 (3.5L), circuit CE436 (VT/OG), harness side and ground.
- Measure the voltage between the PCM C175B-35 (3.7L) or C1381B-35 (5.0L and 6.2L), circuit CE436 (VT/OG), harness side and ground.
Is the voltage greater than 11 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 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.
- 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.
- Make sure that the following preconditions for remote start have been met:
