Brake Switch Circuit Check
- Ensure ignition is off. Disconnect electrical connector at CC ECU. Depress brake pedal. Using voltmeter, check voltage between ground and CC ECU connector terminal No. 4 with brake pedal depressed. SeeFigure . Voltage should be 10-14 volts.
- If voltage is not within specification, check fuses, wiring and electrical connectors for related wiring circuit. See appropriate wiring diagram under WIRING DIAGRAMS . Repair fuses, wiring or electrical connectors as necessary.
- If fuses, wiring and electrical connectors are okay, check brakelight switch. See BRAKELIGHT SWITCH under COMPONENT testing.
