Parking Brake Switch: Odyssey

Disconnect parking brake switch connector from switch. Check for continuity between positive terminal and body ground. With pedal pressed there should be continuity. With pedal released, there should be no continuity. If both ABS or TCS indicator and brake system indicator come on at the same time, diagnose anti-lock/traction control system. See ANTI-LOCK/TRACTION CONTROL - ODYSSEY article.
