1.

Ignition "OFF" & Engine "OFF".

2.

Disconnect the stop lamp switch connector.

3.

Measure resistance between power terminal and siganl terminal of the stop lamp switch connector.

Specification :

Resistance between terminals of the stop lamp 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?

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

Go to "Verification of Vehicle Repair" procedure.

▶ 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.
