3.
Measure resistance between the terminal "1", "2" of the brake switch.
1)
Specification : Resistance between the terminal "1,2" of the brake switch - ∞Ω (when the plunger is pushed down), 0Ω (when the plunger isn’t pushed down).
Ignition "OFF".
Disconnect brake switch connector.
Measure resistance between the terminal "1", "2" of the brake switch.
Specification : Resistance between the terminal "1,2" of the brake switch - ∞Ω (when the plunger is pushed down), 0Ω (when the plunger isn’t pushed down).
Is the measured voltage within specifications?
YES
Fault is intermittent caused by open or short harness in brake light switch, faulty brake light switch or was repaired and HECU memory was not cleared.
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.
