Diagnostic Procedure 10 (Pedal vibration and
noise)
INSPECTION START
1. Apply brake.
2. Start engine.
3. Does the symptom appear only when
engine is started?
No
EYe s
Carry out self-diagnosis.
Refer to BR-59.
CHECK IF SYMPTOM APPEARS.
Does the symptom appear when electrical
equipment switches (such as headlamp)
are operated?
Ye s
ENo
Go toin Diagnostic
Procedure 12, BR-81.
CHECK WHEEL SENSOR.
Check wheel sensor shield ground. For
location of shield ground, refer to wiring
diagram and ªHARNESS LAYOUTº in EL
section.
OK
ENG
Repair wheel sensor.
CHECK HARNESS CONNECTOR.
Check ABS actuator and electric unit pin
terminals for damage or the connection of
ABS actuator and electric unit harness
connector.
Reconnect ABS actuator and electric unit
harness connector. Then retest.
Note: ABS may operate and cause vibration under any of the
following conditions.
Diagnostic Procedure 11 (Long stopping
distance)
CHECK ABS PERFORMANCE
Disconnect ABS actuator and electric unit
connector and check whether stopping
distance is still long.
Ye s
ENo
Go toin Diagnostic
Procedure 12, BR-81.
Perform Preliminary Check and air bleed-
ing.
Note: Stopping distance may be larger than vehicles without
ABS when road condition is slippery.

damage to the anti-corrosion materials. In particular, check the following locations.
Hemmed portion
Hood front end, door lower end, back door rear end, etc.
Panel joint
Side sill of rear fender and center pillar, rear wheel housing of rear fender, around strut tower in engine
compartment, etc.
Panel edge
Back door opening, sunroof opening, fender wheelarch flange, fuel filler lid flange, around holes in panel, etc.
Parts contact
Waist molding, windshield molding, bumper, etc.
Protectors
Damage or condition of mudguard, fender protector, chipping protector, etc.
