Ignition Switch Disarm Function

WARNING: This page is about a different car, the 2004 GMC Sierra, 2004 GMC Cab & Chassis Sierra, 2004 Chevrolet Silverado, and 2004 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

Perform the following steps in order to verify that the ignition disarm function operates:

  1. Stay in the vehicle.
  2. Place the system in the armed state.
  3. Wait for the SECURITY telltale to turn off. The system is armed when the SECURITY telltale turns off.
  4. Cycle the ignition switch from the LOCK position to the RUN position. Return the ignition switch to the LOCK position.
  5. Open any door.

The system does not enter the alarm mode. The SECURITY telltale flashes. The flashing telltale indicates that the system has entered the ready-to-arm state.
