Parking Brake Switch
WARNING: This page is about a different car, the 2002 Suzuki XL-7, 2002 Suzuki Vitara, and 2002 Suzuki Grand Vitara. However, it is still accessible from the selected car via links, so may be relevant.
Disconnect parking brake switch connector. Using DVOM, check for continuity between parking brake switch terminal and ground. Continuity should exist with parking brake applied. With parking brake off (switch depressed), continuity should not exist. If continuity is not as specified, replace parking brake switch.
