WARNING: This page is about a different car, the 2002 GMC Sierra, 2002 GMC Cab & Chassis Sierra, 2002 Chevrolet Silverado, and 2002 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
When the BCM detects the key is in the ignition and the signal is low and the driver door is open, it activates an audible warning. The key-in-ignition chime sounds at the rate of 100 pulses per minute (medium rate chime) until the driver door is closed or the key removed from the ignition switch. The BCM activates the key-in-ignition warning when all of the following occurs:
- The ignition switch is OFF.
- The key-in-ignition switch signal is low.
- The driver door jamb switch signal is low with the driver door open.
