- Found code P0573 for brake switch circuit high voltage. Monitored the live data, depressed and released the brake pedal, and observed the brake light switch status did not change. Checked fuses, relays, wiring harness and connector to switch- ok. Connected a fused jumper wire across the brake light switch harness connector sense circuit and observed the brake light switch status changed. Measured the continuity across the brake light switch, continued to depress and release the brake pedal and found the switch had intermittent continuity. Remove and replace brake light switch, clear codes, and road test vehicle.
