If the brake switch is removed from the brake pedal or it is disconnected from the connector, replace the brake switch with a new one.
1. Measure the voltage between the following terminals and body ground and verify that the voltage is as indicated in the table.
- If the voltage is not as indicated in the table, repair or replace the
brake
switch or wiring harness according to the following indications:
- If terminal B is B+ and terminal D is 1 V or less regardless of the brake pedal status: Replace the brake switch. (Brake switch internal malfunction)
- If terminals B and D are both B+ regardless of the brake
pedal status:
Inspect for continuity between terminals B-D with the
brake switch connector disconnected and the brake pedal
released. If continuity is detected, replace the brake switch.
If continuity is not detected, repair or replace the wiring harness and replace the brake switch with a new one.
