TROUBLE DIAGNOSIS
Actuator operation check
1.
Connect 19 and 21 terminals of actuator to 40 and 41 terminals
of relay box.
2.
Measure the motor voltage (No.4 terminal to body earth) with
oscilloscope. Then check the motor reverse voltage occasioned
time.
The motor reverse voltage occasioned time is more than 0.1
sec.
CAUTION:
●
Perform checking of motor relay unit. Then confirm that
relay functions.
●
Driving actuator motor is with in 4 sec to prevent heating
up.
●
Standard condition of the motor reverse voltage occa-
sioned time is: Battery voltage is 12V. Temperature 20
°
.
when the battery voltage or temperature is lower than the
standard, the motor reverse voltage occasioned time
becomes slightly shorter.
Symptom 1: ABS Works Frequently.

PEDAL FORCE INSPECTION
Check that the brake is effective with the pedal depressed.
Is the pedal heavy, but effective?
YES
>> Normal
NO
>> GO TO 3.
3.
CONNECTOR AND PERFORMANCE INSPECTION
Disconnect the actuator relay unit connector to deactivate the ABS function. Check that the brake is effective.
Is the brake effective?
YES
>> GO TO 4.
NO
>> Brake line inspection
4.
ABS WARNING LAMP INDICATOR INSPECTION
Check that the ABS warning lamp illuminates.
Does the ABS warning lamp illuminate?
YES
>> Perform the self-diagnosis.
NO
>> GO TO 5.
5.
WHEEL SENSOR INSPECTION
Check the wheel sensor system.
●
Sensor mounting inspection
●
Sensor pick-up inspection for iron chips
●
Sensor rotor inspection (e.g. Number of teeth, damaged teeth)
●
Sensor connector engagement inspection
Is inspection result OK?
OK
>> Normal
NG
>> Wheel sensor and rotor lines repair
Symptom 3: Longer Stopping Distance
EFS002XP
Inspection procedure
1.
INSPECTION START
Check that the stopping distance when braking becomes longer only on a snowy or gravel road.
Does the stopping distance when braking become longer only on a snowy or gravel road?
YES
>> It may be longer than that of vehicle without ABS.
NO
>> GO TO 2.
2.
PERFORMANCE CHECK
Disconnect the actuator relay box to deactivate the ABS function.
Is the stopping distance still longer?
YES
>>
●
Brake line air bleeding
●
Brake line inspection
NO
>> GO TO 3.
3.
ABS WARNING LAMP INDICATOR INSPECTION
Check that the ABS warning lamp illuminates.
Does the ABS warning lamp illuminate?
YES
>> Perform the self-diagnosis.
NO
>> GO TO 4.
