Check Wire Between Brake On/Off Switch & ABS Control Module
- With ignition switch in OFF position, connect breakout box with adapter to ABS control module connector. Leave ABS control module disconnected.
- Depress brake pedal and measure voltage on breakout box pin No. 2. If voltage is greater than 10 volts, ABS is okay. If voltage is less than 10 volts, service Green/Black or Yellow/Black wire between brake on/off switch and ABS control module.
NOTE:
The Green/Black wire from module splices into a Yellow/Black wire from the switch.
