The Vehicle Does Not Start With The Passive Key In Certain Areas Within The Vehicle But Starts Using The Passive Key Backup Location

  1. A1 CHECK THE PASSIVE KEY LOCATION 
    • Check the location of the passive key. If it is placed in the far corners of the interior of the vehicle, move the passive key out of these areas and attempt to start the vehicle.

    Does the vehicle start (ready to drive displays in the message center for hybrid vehicles)? 

    • Yes  : The system is OK. INFORM the customer of the normal vehicle operation.
    • No  : GO to A2 
  2. A2 CHECK FOR ENVIRONMENTAL INTERFERENCE 
    • Check for the use of a charger or other wireless device that can cause interference with the passive key. If any device is found, remove the device and attempt to start the vehicle.

    Does the vehicle start (ready to drive displays in the message center for hybrid vehicles)? 

    • Yes  : The system is OK. INFORM the customer of the normal vehicle operation.
    • No  : GO to A3 
  3. A3 CHECK THE SUSPECT ANTENNA 
    NOTE: For a concern with key programming or if unable to start the vehicle with the passive key in the back up slot, follow the diagnostics for the PATS  center antenna.
    • Ignition ON.
    • Using a diagnostic scan tool, perform the BCM  self-test. Record the DTC  .
    • Ignition OFF.
    • Disconnect suspect antenna.
    • Measure:
      PATS CENTER ANTENNA (DTC B10C8:01)

      Positive Lead Measurement/Action Negative Lead
      C634, pin 2, component side OHM C634, pin 3, component side

    Is the resistance between 1 and 3 ohms? 

  4. A4 CHECK THE SUSPECT ANTENNA CIRCUITS FOR A SHORT TO VOLTAGE 
    • Disconnect BCM C2280G  (center PATS  antenna).
    • Disconnect BCM C2280E  (keyless entry rear antenna or exterior front door handle).
    • Measure:
      PATS CENTER ANTENNA

      Positive Lead Measurement/Action Negative Lead
      C325-1  VOLTAGE Ground
      C325-2  VOLTAGE Ground
      KEYLESS ENTRY REAR ANTENNA

      C543-3  VOLTAGE Ground
      PASSENGER EXTERIOR FRONT DOOR HANDLE

      Positive Lead Measurement/Action Negative Lead
      C634-2  VOLTAGE Ground
      C634-3  VOLTAGE Ground

    Is any voltage present? 

    • Yes  : REPAIR the affected circuit.
    • No  : GO to A5 
  5. A5 CHECK THE SUSPECT ANTENNA CIRCUITS FOR A SHORT TO GROUND 
    • Measure:
      PATS CENTER ANTENNA

      Positive Lead Measurement/Action Negative Lead
      C325-1  OHM Ground
      C325-2  OHM Ground
      KEYLESS ENTRY REAR ANTENNA

      Positive Lead Measurement/Action Negative Lead
      C4082-1  OHM Ground
      C4082-2  OHM Ground
      DRIVER EXTERIOR FRONT DOOR HANDLE

      Positive Lead Measurement/Action Negative Lead
      C543-2  OHM Ground
      C543-3  OHM Ground
      PASSENGER EXTERIOR FRONT DOOR HANDLE

      Positive Lead Measurement/Action Negative Lead
      C634-2  OHM Ground
      C634-3  OHM Ground

    Are the resistances greater than 10, 000 ohms? 

    • Yes  : GO to A6 
    • No  : REPAIR the affected circuit.
  6. A6 CHECK THE SUSPECT ANTENNA CIRCUITS FOR AN OPEN 
    • Measure:
      PATS CENTER ANTENNA

      Positive Lead Measurement/Action Negative Lead
      C325-1  OHM C2280G-40 
      C325-2  OHM C2280G-27 
      KEYLESS ENTRY REAR ANTENNA

    Are the resistances less than 3 ohms? 

  7. A7 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION 
    • Disconnect and inspect all of the BCM  connectors.
    • Repair:
      • corrosion (install new connectors or terminals, clean module pins)
      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary
    • Reconnect all the BCM  connectors and 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 OASIS  for any applicable Technical Service Bulletins (TSBs). If a TSB  exists for this concern, DISCONTINUE this test and FOLLOW TSB  instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new BCM  .

      REFER to: BODY CONTROL MODULE (BCM) .

    • 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.
