Is the inspection result normal? YES >> Perform trouble diagnosis for battery power supply. Refer to PG-10, "Wiring Diagram - BATTERY POWER SUPPLY -".
NO >> Repair or replace error-detected parts.
5.CHECK ACTUATOR RELAY, ABS IN VALVE, ABS OUT VALVE POWER SUPPLY
1. Turn the ignition switch OFF.
2. Check voltage between ABS actuator and electric unit (control unit) harness connector and ground.
3. Turn the ignition switch ON
CAUTION:
Never start engine.
4. Check voltage between ABS actuator and electric unit (control unit) harness connector and ground.
Is the inspection result normal? YES >> GO TO 7.
NO >> GO TO 6.
6.CHECK ACTUATOR RELAY, ABS IN VALVE, ABS OUT VALVE POWER SUPPLY CIRCUIT
1. Turn the ignition switch OFF.
2. Check 50 A fusible link (I).
3. Check continuity and short circuit between ABS actuator and electric unit (control unit) harness connector terminal (2) and 50 A fusible link (I).
Is the inspection result normal? YES >> Perform trouble diagnosis for battery power supply. Refer to PG-10, "Wiring Diagram - BATTERY POWER SUPPLY -".
NO >> Repair or replace error-detected parts.
7.CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) GROUND CIRCUIT
Check for continuity between ABS actuator and electric unit (control unit) harness connector and the ground.
Is the inspection result normal? YES >> GO TO 8.
NO >> Repair or replace error-detected parts.
8.CHECK TERMINAL
