Chryslers cry wolf

Various 2010 Chrysler vehicles may exhibit a theft alarm that intermittently sounds for no apparent reason, accompanied by a no-start. This applies to 2010 Town & Country/Grand Caravan, Journey, Jeep Nitro, Jeep Wrangler, Liberty and Cherokee vehicles, equipped with the Security Alarm or Premium Security Alarm systems.

Multiple attempts are required to start the engine when this occurs.

  1. Using a scan tool (wiTECH) with the appropriate diagnostic procedures available in TechCONNECT, verify that no DTCs are present. If DTCs are found, record them and repair as necessary before proceeding.
  2. In the System Test tab of wiTECH, record the “Last VTA Trigger” cause.
  3. Was the “Last VTA Trigger” equal to 1 (right rear door)?
    1. Yes: Perform the repair procedure.
    2. No: This bulletin does not apply. Proceed to Step 4.
  4. Are DTCs U0010 AND U0001 present in the TIPM?
    1. Yes: Perform the repair procedure.
    2. No: This bulletin does not apply. Further diagnosis is necessary.


Install a battery charger to ensure that battery voltage does not drop below 13.2 volts. Do not allow charging voltage to climb above 13.5 volts during the flash process.

  1. Flash reprogram the TIPM. Help using the wiTECH Diagnostic Application for flashing the TIPM is made available through the wiTECH Diagnostic Application. For instructions, select the “HELP” tab on the upper portion of the wiTECH window, then “HELP CONTENTS.”
  2. Clear any DTCs that may have been set in other modules due to reprogramming.
