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 Controller Anti-Lock Brake (CAB) module, Air Bag Control Module (ACM) and Sentry Key Immobilizer Module (SKIM). If replacing PCM and vehicle is equipped with SKIM, secret key data must also be updated to enable engine starting. See PROGRAMMING .

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 from vehicle owner or manufacturer. Remove all test equipment and jumper wires. Connect any disconnected components. Go to next step.
Connect DRBIII® to Data Link Connector (DLC). Turn ignition on. Using DRBIII®, select SKIM MODULE REPLACEMENT. Enter 4-digit PIN number to put SKIM in access mode. Go to next step.
Using DRBIII®, select THEFT ALARM, SKIM, MISCELLANEOUS, then select desired procedure and follow steps displayed on DRBIII®. If SKIM has been replaced, ensure all keys and remote transmitters to be used with vehicle are programmed into SKIM. Go to next step.

NOTE: Prior to returning vehicle to the customer, perform a module scan to be sure that all DTCs are erased. Erase any DTCs that are found.

Using DRBIII®, clear DTCs. Perform 5 ignition key cycles (key on/key off) leaving key on for at least 90 seconds per key cycle. Using DRBIII®, read the SKIM DTCs. Are there any SKIM DTCs? If no, system is operating correctly and customer's complaint cannot be duplicated, repair is complete. If yes, perform appropriate test. See DIAGNOSTIC TROUBLE CODE DEFINITIONS .
