2002 Chrysler PT Cruiser Base, AutomaticFACTORY OEM SERVICE PROCEDURE

Body Verification Test

CAUTION: Always turn ignition off before disconnecting or connecting any control module connectors. Failure to do so could result in damage to control module.
  1. Disconnect all jumper wires and reconnect all previously disconnected components and connectors.
  2. If the sentry key immobilizer module or the powertrain control module was replaced, proceed to step Β 6. If the SKIM or PCM was not replaced, continue to the next step.
  3. If the remote keyless entry module was replaced, turn the ignition on for 15 seconds (to allow the new RKE module to learn VIN) or engine may not start (if VTSS equipped). If the vehicle is equipped with VTSS, use the DRBIII and enable VTSS.
  4. Program all other options as needed.
  5. If any repairs were made to the HVAC system, disconnect the battery or, using the DRBIII, recalibrate the HVAC doors. Proceed to step Β 13.
  6. Obtain the vehicles unique PIN assigned to its original SKIM from either the vehicles invoice or from Chryslers customer assistance center (1-800-992-1997).
  7. Once secured access mode is active, the SKIM will remain in that mode for 60 seconds.
  8. With the DRBIII, select THEFT ALARM, SKIM, MISCELLANEOUS and select SKIM REPLACED. Enter the 4 digit PIN to put the SKIM in secured access mode.
  9. The DRBIII will prompt for the following steps:
    • Program the country code into the SKIMs memory.
    • Program the vehicles VIN into the SKIM memory.
    • Transfer the vehicles secret key data from the PCM.
  10. Using the DRBIII, program all customer keys into the SKIM memory. This requires that the SKIM be in secured access mode, using the 4 digit PIN.
  11. If the PCM is replaced, the VIN and the unique secret key data must be transferred from the SKIM to the PCM. This procedure requires the SKIM to be placed in secured access mode using the 4-digit PIN.
  12. If 3 attempts are made to enter secured access mode using an incorrect PIN, secured access mode will be locked out for 1 hour which causes the DRBIII to display BUS +\- SIGNALS OPEN. To exit this mode, turn ignition to run for 1 hour.
  13. Ensure that all accessories are turned off and the battery is fully charged.
  14. Ensure that the ignition is on.
  15. With the DRBIII, record and erase all DTCs from all modules. Start and run the engine for 2 minutes. Operate all functions of the system that caused the original concern.
  16. Turn the ignition off and wait 5 seconds. Turn the ignition on and using the DRBIII, read DTCs from all modules.
