  4. Is the measured value within specifications?

    YES 

    • Fault is intermittent caused by poor connection in brake light switch harness and/or HECU's connector. 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.
