TROUBLE DIAGNOSIS FOR SYSTEM

4. CHECK DATA MONITOR
1. Connect ABS actuator and electric unit (control unit) connector and steering angle sensor.
2. Perform “ST ANGLE SIG” at “DATA MONITOR” to check if the status is normal.
OK or NG
OK >> Perform self-diagnosis again.

BRC-40, "
Adjustment of Steering Angle Sensor Neutral Position" .
Yaw Rate/Side/Decel G Sensor SystemBFS000EC
CAUTION:
When the vehicle turns sharply, such as a spin turn, accel turn, or drift driving, while the VDC function
is OFF (VDC OFF indicator lamp turns on), a malfunction may occur in the yaw rate/side/decel G sen-
sor system, so in this case, restart the engine, and if it recovers normally, there is no malfunction.
Always erase memory after that. Refer to BRC-58, "
ERASE MEMORY" .
INSPECTION PROCEDURE
1. CHECK SELF-DIAGNOSTIC RESULTS
Check 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 ABS actuator and electric unit (control unit) connector and yaw rate/
side/decel G sensor connector, and check the terminal for deformation, disconnection, looseness, and so
on. Repair or replace the malfunctioning part if there are.
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.

Removal and InstallationBFS000EQ
COMPONENTS
REMOVAL
Be careful of the following.
CAUTION:
When removing the wheel sensor, do not rotate it if possible, and do not forcibly pull the wheel sensor
harness.
INSTALLATION
Note the following, and tighten bolts to the specified torque.

Check the inside of the wheel sensor mounting hole for foreign materials, the rotor surface for iron chips
and other foreign materials. Clean both the wheel sensor mounting hole and the rotor surface before
installation. Replace the wheel sensor if there is any non-standard condition.

Completely push in rubber clamp of strut bracket and body bracket until they lock when installing front
wheel sensor so that the wheel sensor harness will not be twisted. Install grommet groove onto bracket
with yellow line on the harness facing bracket opening (mounting hole). There should be no twists in the
harness when installed.

When installing the rear sensor, securely install the harness mount of the rear suspension member so that
the wheel sensor harness is not twisted. In addition, there should be no twists in the harness when
installed.
