Brake light switch Check

1. IG "OFF".
2. Disconnect the brake light switch connector.
3. Measure resistance between power terminal and signal terminal of the brake light switch connector.

   Specification: 

   Resistance between terminals of the brake light switch - ∞Ω (when the plunger is pushed down), 0Ω (when the plunger isn't pushed down).

   Resistance between the terminals of the brake switch - ∞Ω (when the plunger is not pushed down), 0Ω (when the plunger is pushed down).

4. Is the measured value within specifications?

YES 

• Substitute with a known-good stop signal relay and check for proper operation. If problem is corrected, replace stop signal relay and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.

NO 

• Substitute with a known-good brake light switch and check for proper operation. If problem is corrected, replace brake light switch and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
