Pinpoint Test AO : The Remote Start Feature Is Inoperative

NOTE: This pinpoint test does not diagnose dealer or aftermarket installed remote start systems.

  1. AO1 CHECK THE REMOTE START FEATURE ENABLE/DISABLE SETTING

    • Ignition ON.
    • Using the steering wheel control switch, check the remote start feature setting in the IPC message center.

    Is the remote start feature enabled? 

    Yes  GO to  AO2.
    No  ENABLE the remote start feature.

  2. AO2 CHECK FOR POWERTRAIN DTCs

    • Using a diagnostic scan tool, carry out the PCM KOEO and KOER self-tests.

    Are any PCM DTCs present? 

    Yes  REFER to the PCM DTC Chart .
    No  GO to  AO3.

  3. AO3 CHECK FOR BCM DTCs

    • Using a diagnostic scan tool, carry out the BCM self-test.

    Are any BCM DTCs present? 

    Yes  REFER to the BCM DTC Chart .
    No  GO to  AO4.

  4. AO4 CHECK FOR RFA MODULE DTCs

    • Using a diagnostic scan tool, carry out the RFA module self-test.

    Are any RFA module DTCs present? 

    Yes  REFER to the RFA Module DTC Chart .
    No  GO to  AO5.

  5. AO5 CHECK THE RKE FUNCTIONALITY

    • Ignition OFF.
    • Using the RKE function of the passive key, press the liftgate release button twice, the lock button and then the unlock button.

    Do all the functions tested of the RKE transmitter operate (lock, unlock and power liftgate open)? 

    Yes  GO to  AO6.
    No  If all of the functions are inoperative, GO to Pinpoint Test AL .If an individual function is inoperative, GO to Pinpoint Test AM .

  6. AO6 CHECK THE WAKE-UP CIRCUIT FOR VOLTAGE AT THE PCM (POWERTRAIN CONTROL MODULE) USING THE BCM (BODY CONTROL MODULE) PID (PARAMETER IDENTIFICATION) (PCM) WAKE-UP OUTPUT CONTROL (PCM_WKUP_CTRL)

    • Ignition OFF.
    • Disconnect: PCM B connector.
    • Ignition ON.
    • Using a diagnostic scan tool, command the BCM PID PCM_WKUP_CTRL on.
    • Measure:
      Positive Lead Measurement / Action Negative Lead

      		 Ground

    Is the voltage greater than 11 volts? 

    Yes  GO to  AO8.
    No  GO to  AO7.

  7. AO7 CHECK THE WAKE-UP CIRCUIT FOR AN OPEN

    • Ignition OFF.
    • Measure:

      		 C2280F-5

    Is the resistance less than 3 ohms? 

    Yes  GO to  AO9.
    No  REPAIR the circuit.

    • Close all the doors, the hood and the liftgate.
    • Using the passive key:
      • Press the door lock button.
      • Press the remote start button twice.

    Does the vehicle remotely start? 

    Yes  The system is operating correctly. INFORM the customer of the correct vehicle remote start operation.
    No  REPLACE the suspect passive key. PROGRAM the new passive key. REFER to Key Programming Using Diagnostic Equipment in Anti-Theft Passive Anti-Theft System (PATS) .

  9. AO9 CHECK FOR CORRECT BCM OPERATION

    • Disconnect and inspect all the BCM connectors.
    • Repair:
      • corrosion (install new connector or terminals - clean module pins)
      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary
    • Reconnect the BCM connectors. Make sure they seat and latch correctly.
    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    Yes  CHECK On-Line Automotive Service Information System (OASIS) for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, BCM Hardware Testing
    No  The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
