The Sentry Key Immobilizer System (SKIS) must be initialized following a Wireless Ignition Node (WIN) (also known as Sentry Key Immobilizer Module/SKIM, Sentry Key REmote Entry Module/SKREEM or Wireless Control Module/WCM) replacement. SKIS initialization requires the use of a diagnostic scan tool. Initialization will also require that you have access to the unique four-digit PIN code that was assigned to the original WIN. The PIN code must be used to enter the Secured Access Mode in the WIN. This PIN number may be obtained from the vehicle owner, from the original vehicle invoice, or from the DaimlerChrysler Customer Center. Refer to STANDARD PROCEDURE .

NOTE: If a Powertrain Control Module (PCM) or a shaft lock module is replaced on a vehicle equipped with the Sentry Key Immobilizer System (SKIS), the unique Secret Key data must be transferred from the Wireless Ignition Node (WIN) (also known as the Sentry Key Immobilizer Module/SKIM, Sentry Key REmote Entry Module/SKREEM or the Wireless Control Module/WCM) to the new PCM or shaft lock module using the appropriate programming procedure. This procedure also requires the use of a diagnostic scan tool and the unique four-digit PIN code to enter the Secured Access Mode in the WIN. Refer to the appropriate diagnostic information for the proper PCM or shaft lock module replacement procedures.

• You smell fuel, burning insulation, or see smoke.

• Brakes feel soft, pull hard to one side, or make grinding noises.

• The engine overheats, stalls repeatedly, or misfires under load.

• You are missing required tools, torque specs, or safe lifting equipment.
