C1113, C1145, C1146 YAW RATE/SIDE/DECEL G SENSOR

C1113, C1145, C1146 YAW RATE/SIDE/DECEL G SENSOR

Description

INFOID:0000000009479276

The yaw rate/side/decel G sensor detects the yaw rate/side/decel G affecting the vehicle, and transmits the

data to the ABS actuator and electric unit (control unit) as an analog voltage signal.

DTC CONFIRMATION PROCEDURE

1.

CHECK SELF-DIAGNOSIS RESULTS

Check the self-diagnosis results.

Is above displayed on the self-diagnosis display?

YES

>> Proceed to diagnosis procedure. Refer to 

BRC-48, "Diagnosis Procedure"

.

NO

>> Inspection End

Diagnosis Procedure

INFOID:0000000009479278

Regarding Wiring Diagram information, refer to 

BRC-92, "Wiring Diagram - VDC WITHOUT HILL DESCENT

CONTROL/HILL START ASSIST"

.

CAUTION:

• Sudden turns (such as spin turns, acceleration turns), drifting, etc. when VDC function is OFF may

cause the yaw rate/side/decel G sensor system to indicate a malfunction. This is not a malfunction if

normal operation can be resumed after restarting the engine.

• If vehicle is on turn table at entrance to parking garage, or on other moving surface, VDC OFF indica-

tor lamp may illuminate and CONSULT self-diagnosis may indicate yaw rate sensor system malfunc-

tion. However, in this case there is no malfunction in yaw rate sensor system. Take vehicle off of turn

table or other moving surface, and start engine. Results will return to normal.

1.

CONNECTOR INSPECTION

1. Disconnect the ABS actuator and electric unit (control unit) connector and yaw rate/side/decel G sensor

connector. 

2. Check the terminals for deformation, disconnection, looseness or damage.
Is the inspection result normal?

YES

>> GO TO 2

NO

>> Repair or replace as necessary.

C1115 ABS SENSOR [ABNORMAL SIGNAL]

Description

INFOID:0000000009479281

When the sensor rotor rotates, the magnetic field changes. It converts the magnetic field changes to current

signals (rectangular wave) and transmits them to the ABS actuator and electric unit (control unit).

CHECK WHEEL SENSOR OUTPUT SIGNAL

1. Connect ABS active wheel sensor tester (J-45741) to wheel sensor using appropriate adapter.

2. Turn on the ABS active wheel sensor tester power switch.

NOTE:

The green POWER indicator should illuminate. If the POWER indicator does not illuminate, replace the

battery in the ABS active wheel sensor tester before proceeding.

3. Spin the wheel of the vehicle by hand and observe the red SENSOR indicator on the ABS active wheel

sensor tester. The red SENSOR indicator should flash on and off to indicate an output signal.

NOTE:

If the red SENSOR indicator illuminates but does not flash, reverse the polarity of the tester leads and

retest.

Does the ABS active wheel sensor tester detect a signal?
