SKIM Theft Alarm System

Connect scan tool to Data Link Connector (DLC). Go to ENGINE, MISC. Using appropriate PIN code for this vehicle, place SKIM in Secured Access mode. Select UPDATE SECRET KEY DATA. Data will be transferred from SKIM to PCM.

Inspect vehicle to ensure all engine components are connected. Reassemble and reconnect components as necessary. If DTCs have not been diagnosed, go to DTC TEST and finish diagnosing remaining DTCs as necessary. If all DTCs have been diagnosed, perform the following procedure:

A Leak Detection Pump (LDP) test mode has been added to scan tool to verify LDP system repairs. A scan tool software program was written which causes PCM to run LDP monitor as part of this procedure. Test failures will be indicated through a stored DTC.

NOTE: The software program makes temporary changes to the operating mode of PCM. It is CRITICAL that this test not be interrupted. A PCM left in this mode as a result of an interrupted test will illuminate MIL for 8-10 minutes of driving with no stored DTCs. Erasing DTCs will not change this condition.

If a vehicle is stuck in the mode described in the note above, re-run LDP test in its entirety so software program in scan tool can restore PCM operating mode.

Note the similarity of LDP monitor screen found under OBDII MONITORS. Failure modes are fewer in this system test than in OBDII LDP MONITOR. System test will only store SMALL LEAK DTC to indicate a problem with the system. No other type of failure mode is given. If system test failure is due to a large leak, PCM will set SMALL LEAK DTC to indicate failures that occurred as part of system test.

  1. Connect scan tool to data link connector. Turn off all accessories.
    NOTE: For next step (test) to be valid, engine must remain at idle, transmission in Park, and no throttle pedal input for entire test.
  2. With scan tool in LDP test mode, follow screen prompts.
  3. If a small leak DTC has set, repair is not complete. Check for any related Technical Service Bulletins (TSBs) and return to DTC TEST. If another DTC has set, return to DTC TEST and follow specified path. If there are no new DTCs, repair is complete.
