TROUBLE DIAGNOSES FOR SYMPTOMS
3.CHECK CONNECTOR AND BRAKING PERFORMANCE
1. Disconnect ABS actuator and electric unit (control unit) connector.
2. Check brake effectiveness.
NOTE:
Driving the vehicle with the ABS actuator and electr ic unit (control unit) disconnected may induce DTCs in
electrical control units using CAN communication. After the inspection, clear all DTCs. Refer to BRC-60,
"CONSULT-III Function (ABS)".
OK or NG
OK >> GO TO 4.
NG >> Perform Basic Inspection. Refer to BRC-56, "
Basic Inspection".
4.CHECK WHEEL SENSORS
Check the following.
• Wheel sensor mounting for looseness
• Wheel sensors for physical damage
• Wheel sensor connectors for terminal damage or loose connections
OK or NG
OK >> Check ABS actuator and electric unit (contro l unit) pin terminals for damage and the connection of
harness connector. Reconnect ABS actuator and el ectric unit (control unit) harness connector.
Then retest.
NG >> Repair as necessary.
Long Stopping DistanceINFOID:0000000005928500
1.CHECK BASE BRAKING SYSTEM PERFORMANCE
1. Disable ABS by disconnecting ABS actuator and electric unit (control unit) connector.
2. Drive vehicle and check to see if stopping distance is still long.
NOTE:
Driving the vehicle with the ABS actuator and electr ic unit (control unit) disconnected may induce DTCs in
electrical control units using CAN communication. After the inspection, clear all DTCs. Refer to BRC-60,
"CONSULT-III Function (ABS)".
OK or NG
OK >> Go to BRC-81, "ABS Works Frequently".
NG >> Perform Basic Inspection. Refer to BRC-56, "
Basic Inspection".
NOTE:
Stopping distance may be longer than vehicles without ABS when road condition is slippery.
ABS Does Not WorkINFOID:0000000005928501
CAUTION:
The ABS does not operate when the vehicle speed is 10 km/h (6 MPH) or less.
1.CHECK WARNING LAMP ACTIVATION
Turn ignition switch ON and check for warning lamp activation.
• Warning lamp should activate for approximately 2 seconds after turning the ignition switch ON.
OK or NG
OK >> Carry out self-diagnosis. Refer to BRC-60, "CONSULT-III Function (ABS)".
NG >> Go to BRC-83, "
ABS Warning Lamp Does Not Come On When Ignition Switch Is Turned On".
Pedal Vibration or ABS Operation NoiseINFOID:0000000005928502
NOTE:
During ABS activation, pedal vibration may be felt and a noise may be heard. This is normal and does not indi-
cate a malfunction.

Adjustment of Steering Angle Sensor Neutral PositionINFOID:0000000005928506
After removing/installing or replacing ABS actuator and electric unit (control unit), steering angle sensor, steer-
ing and suspension components which affect wheel alignment or after adjusting wheel alignment, be sure to
adjust neutral position of steering angle sensor before running vehicle.
NOTE:
Adjustment of steering angle sensor neutral position requires CONSULT-III.
1. Stop vehicle with front wheels in straight-ahead position.
2. Connect CONSULT-III to data link connector on vehicle, and turn ignition switch ON (do not start engine).
3. Touch “ABS”, “WORK SUPPORT” and “ST ANGLE SENSOR ADJUSTMENT” on CONSULT-III screen in
this order.
4. Touch “START”. CAUTION:
Do not touch steering wheel whil e adjusting steering angle sensor.
5. After approximately 10 seconds, touch “END”. (After approximately 60 seconds, it ends automatically.)
6. Turn ignition switch OFF, then turn it ON again.
7. Run vehicle with front wheels in straight-ahead position, then stop.
8. Select “DATA MONITOR”, “SELECTION FROM MENU”, and “STR ANGLE SIG” on CONSULT-III screen.
Then check that “STR ANGLE SIG” is within 0 ±2.5 deg. If value is more than specification, repeat steps 1
to 5.
9. Erase memory of ABS actuator and electric unit (control unit) and ECM.
10. Turn ignition switch to OFF.

The top portion of the figure (front side) shows the view from LH side of the vehicle. The RH side is the mirror image of the LH side.
FRONT WHEEL SENSOR
Removal
CAUTION:
• As much as possible, avoid rotating wheel sensor when removing it
. Pull wheel sensors out without
pulling on sensor harness.
• Take care to avoid damaging wheel sensor edges or rotor teeth. Remove wheel sensor first before
removing front or rear wheel hub. This is to avoid damage to wheel sensor wiring and loss of sensor
function.
1. Remove the front wheel and tire. Refer to WT-7, "
Adjustment".
2. Remove the front fender protector. Refer to EI-26, "
Removal and Installation".
3. Disconnect the front wheel sensor connector.
4. Remove the front wheel sensor.
Installation
Installation is in the reverse order of removal.
CAUTION:
• When installing, make sure there is no foreign material such as iron chips on and in the mounting
hole of the wheel sensor. Make sure no foreign material has been caught in the sensor rotor. Remove
any foreign material and clean the mount.

function.
1. Disconnect the rear wheel sensor connector.
2. Remove the rear wheel sensor.
Installation
Installation is in the reverse order of removal.
CAUTION:
• When installing, make sure there is no foreign mate rial such as iron chips on and in the mounting
hole of the wheel sensor. Make sure no foreign material has been caught in the sensor rotor. Remove
any foreign material and clean the mount.
• When installing rear wheel sensor, press rubber grommets of suspension arm bracket and harness
of side member all the way in until they get locked , and be careful not to apply a twist to harness.
Harness should not be twisted after installati on. (Aim the paint mark upward of vehicle.)
