ABS ACTUATOR AND ELECTRIC UNIT
●
Disconnect each ABS actuator and electric unit E64 connector.
Confirm continuity and resistance value between each pair of
ABS actuator and electric unit harness connector.
CAUTION:
Be sure ABS motor is securely grounded.
Basic Inspection
EFS002W8
BASIC INSPECTION 1 BRAKE FLUID LEVEL AND LEAKAGE INSPECTION
1.
Check fluid level in brake reservoir tank. If fluid level is low, refill brake fluid.
2.
Check area around brake piping and ABS actuator and electric unit for leaks. If a leak or oozing is
detected, check as follows:
●
If connections at ABS actuator and electric unit are loose, tighten piping to the specified torque. Then
check again for leaks, and be sure there is no fluid leak.
●
If the flare nuts at the connections and the threads of the ABS actuator and electric unit are damaged,
replace the damaged parts. Then check again for leaks, and make sure that there is no fluid leak.
●
If leak or oozing is detected except for ABS actuator and electric unit connections, wipe it with clean
cloth. Then check again for leaks. If there is still leak or oozing, replace damaged part.
●
If leak or oozing is detected on ABS actuator and electric unit, wipe with a clean cloth. Check again for
leaks, and if there is still leak or oozing, replace ABS actuator and electric unit.
CAUTION:
ABS actuator and electric unit body cannot be disassembled.
BASIC INSPECTION 2 INSPECTION FOR LOOSE POWER SUPPLY TERMINAL
Check battery for looseness on battery positive/negative terminals and ground connection.

INSPECTION PROCEDURE
1.
TIRE INSPECTION
Check air pressure, wear, and size.
Are air pressure, wear, and size within specifications?
YES
>> GO TO 2.
NO
>> Adjust air pressure, or replace tire.
2.
SENSOR ROTOR INSPECTION
Check sensor rotor tooth for damage.
Is inspection result OK?
OK
>> GO TO 3.
NG
>> Replace sensor rotor.
3.
CHECK THE CONNECTOR
1. Remove both the malfunctioning wheel sensor (identified at con-
trol unit) and the ABS actuator and electric unit connector. Check the
deformation of the terminal or if the connection is at the incomplete
state. Then connect the connectors.
2.Operate self-diagnosis.
Does ABS warning lamp illuminate?
YES
>> GO TO 4
NO
>> Check is completed.
4.
CHECK WHEEL SENSOR.
Check internal resistance of wheel sensor.
Is inspection result OK?
OK
>> GO TO 5.
NG
>> Replace wheel sensor.
