TROUBLE DIAGNOSIS FOR SYSTEM

Pump Motor, Motor Relay SystemBFS000ED
INSPECTION PROCEDURE
1. CHECK SELF-DIAGNOSTIC RESULTS
Check the self-diagnostic results.
Is above displayed on self-diagnosis display?
YES >> GO TO 2.
NO >> INSPECTION END
2. CHECK CONNECTOR
1. Turn ignition switch OFF, disconnect the ABS actuator and electric unit (control unit) connector, and check
terminal for deformation, disconnection, looseness, and so on. If there is a malfunction, repair or replace
the terminal.
2. Securely reconnect connectors and perform self-diagnosis again.
OK or NG
OK >> Connector terminal contact was loose, damaged, open or shorted.
NG >> GO TO 3.
3. CHECK ABS MOTOR AND MOTOR RELAY POWER SYSTEM
1. Turn ignition switch OFF and disconnect ABS actuator and elec-
tric unit (control unit) connector.
2. Check voltage between the ABS actuator and electric unit (con-
trol unit) harness connector E241 terminal 1 and ground.
OK or NG
OK >> GO TO 4.
NG >> Circuit malfunction between battery and ABS actuator
and electric unit (control unit). Repair circuit.
4. CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) GROUND CIRCUIT

ABS actuator and electric unit (control unit) harness connector
E241 terminals 31, 46 and ground.
OK or NG
OK >> Replace ABS actuator and electric unit (control unit).
NG >> Harness or connector is open or shorted. Repair or
replace malfunctioning components.

Removal and InstallationBFS000ET
REMOVAL
CAUTION:

Do not drop or strike G sensor, because it has little endurance to impact.

Do not power tool etc., because G sensor is weak for the impact.
1. Remove center console. Refer to IP-14, "
(J) Center Console" , “INSTRUMENT PANEL ASSEMBLY”.
2. Disconnect G sensor harness connector.
3. Remove G sensor mounting bolts. Then remove yaw rate/side/
decel G sensor.
INSTALLATION
Installation is the reverse order of the removal.
CAUTION:
Do not drop or strike G sensor, because it has little endurance to impact.
