Circuit Description

Relay supplies power to each ABS solenoid. After ignition switch is turned on, relay turns on if initial check is okay. DTC is set when ECU detects zero voltage at terminal No. 1 (Gray/Green wire) on ABS control relay connector A7, or battery voltage at terminal No. 2 (Red wire) on ABS actuator connector A4. Possible causes are:

• ABS control relay.
• ABS control relay circuit short to battery voltage.
• ECU.
