Status	Terminal
	A	B	C	D
Brake pedal depressed	B+	B+	1 V or less	B+
Brake pedal is released	1 V or less	B+	1 V or less	1 V or less

•  If the voltage is not as indicated in the table, repair or replace the brake switch or wiring harness according to the following indications:

a.  If terminal A is B+ and terminal C is 1 V or less regardless of the brake pedal status:

Replace the brake switch. (Brake switch internal malfunction)

b.  If terminals A and C are both B+ regardless of the brake pedal status:

Inspect for continuity between terminals A—C with the brake switch connector disconnected and the brake pedal depressed.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. (Short in internal brake switch or circuit related to brake switch)

c.  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)

d.  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. (Short in internal brake switch or circuit related to brake switch)
