Skis Verification Test

NOTE: If replacing Powertrain Control Module (PCM), the correct vehicle mileage and Vehicle Identification Number (VIN) must be programmed into PCM to prevent Diagnostic Trouble Codes (DTC) from being stored in Anti-Lock Brake System (ABS) module and Air Bag Control Module (ACM). If replacing PCM and vehicle is equipped with a Smart Key Immobilizer Module (SKIM), secret key data must also be updated to enable engine starting.

NOTE: Sentry Key Immobilizer Module (SKIM) will only remain in secured access mode for 60 seconds. If incorrect unique Personal Identification Number (PIN) is entered 3 times, SKIM will be locked for one hour. To unlock SKIM, turn ignition on for one hour. When SKIM is locked, scan tool will display BUS +/- SIGNALS OPEN.

Obtain vehicle's unique Personal Identification Number (PIN) assigned to SKIM module from vehicle owner or manufacturer. Remove all test equipment and jumper wires. Connect any disconnected components. Go to next step.
Connect scan tool to Data Link Connector (DLC). Turn ignition on. Using scan tool, select SKIM MODULE REPLACEMENT. Enter 4-digit PIN number to put Sentry Key Immobilizer Module (SKIM) in access mode. Go to next step.
Using scan tool, select THEFT ALARM, SKIM, MISCELLANEOUS, then select desired procedure and follow steps displayed on scan tool. If SKIM has been replaced, ensure all keys and remote transmitters to be used with vehicle are programmed into SKIM. Go to next step.
Using scan tool, retrieve DTCs from all modules. If no DTCs exist, system is operating correctly and customer's complaint cannot be duplicated, repair is complete. If any DTCs exist, perform appropriate test(s). See DTC MESSAGES & CODES table under DIAGNOSTIC TROUBLE CODE DEFINITIONS.
