WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2002 GMC Yukon XL, 2002 GMC Yukon, 2002 Chevrolet Tahoe, 2002 Chevrolet Suburban, and 2002 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

  1. 2:  Listen for an audible click when the Start 1 relay operates. Turn the ignition switch back and forth from the ON to START positions. Repeat this as necessary.

  4. 5:  Tests if ground is constantly being applied to the Start 1 relay.
