VEHICLE JERKS DURING

Description

INFOID:0000000009651449

The vehicle jerks when VDC function, TCS function, ABS function, EBD function or brake limited slip differen-
tial (BLSD) function operates.

Diagnosis Procedure

INFOID:0000000009651450

1.

CHECK SYMPTOM

Check that the vehicle jerks when VDC function, TCS function, ABS function, EBD function or brake limited
slip differential (BLSD) function operates.

Is the inspection result normal?

YES

>> Normal

NO

>> GO TO 2.

2.

PERFORM SELF-DIAGNOSIS

With CONSULT

Perform self-diagnosis for “ABS”.
Is any DTC detected?

YES

>> Check the DTC. Refer to 

BRC-38, "DTC Index"

.

NO

>> GO TO 3.

3.

CHECK CONNECTOR

With CONSULT

1.

Turn the ignition switch OFF.

2.

Disconnect ABS actuator and electric unit (control unit) harness connector.

3.

Check connector terminal for deformation, disconnection and looseness.

4.

Connect harness connector and perform self-diagnosis for “ABS” again.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Poor connection of connector terminal. Repair or replace connector terminal.

4.

CHECK ECM AND TCM SELF-DIAGNOSIS RESULTS

With CONSULT

Perform self-diagnosis for “ENGINE” and “TRANSMISSION”.

Is any DTC detected?

YES

>> Check the DTC.

NO

>> Replace ABS actuator and electric unit (control unit). Refer to 

BRC-123, "Removal and Installa-

tion"

.

[WITH VDC]

NORMAL OPERATING CONDITION

NORMAL OPERATING CONDITION

Description

INFOID:0000000009651451

Symptom

Result

Brake pedal slightly vibrates and operation sound (motor sound and sound from suspen-
sion) occurs when VDC function, TCS function, ABS function, EBD function or brake limited 
differential (BLSD) function operates.

This is not a malfunction, The symptom 
occurs VDC function, TCS function, ABS 
function, EBD function and brake limited 
differential (BLSD) function that are nor-
mally operated.

Brake stopping distance may become longer than models without ABS function depending 
on the road conditions, when ABS function is operated on slippery road like rough road, 
gravel road or snowy road.

Brake pedal vibrates and operation sound occurs during sudden acceleration and corner-
ing, when VDC function, TCS function or brake limited slip differential (BLSD) function is 
operated.

Brake pedal vibrates and motor sound from the engine room occurs, when the engine starts 
or the vehicle starts just after starting the engine.

This is not a malfunction, because it is 
caused by operation check of ABS actua-
tor and electric unit (control unit).

Acceleration may be felt insufficient depending on the road conditions.

This is not a malfunction, because it is 
caused by TCS function that puts the 
highest priority to obtain the optimum 
traction (stability).

TCS function may operate momentarily, while driving on a road where friction coefficient 
varies, or when downshifting, or fully depressing accelerator pedal.

VDC warning lamp may turn ON, when the vehicle is on a rotating turntable or is given a 
strong shaking or large vibrations on a ship while the engine is running.

In this case, restart the engine on a nor-
mal road. If the normal condition is re-
stored, there is no malfunction. In that 
case, erase “ABS” self-diagnosis result 
memory with CONSULT.

VDC warning lamp may turn ON and VDC function, TCS function and brake limited slip dif-
ferential (BLSD) function may not normally operate, when driving on a special road the is 
extremely slanted (bank in a circuit course).

A malfunction in yaw rate/side G sensor system may be detected when the vehicle sharply 
turns during a spin turn, acceleration turn or drift driving while VDC function, TCS function 
and brake limited slip differential (BLSD) function are OFF (VDC OFF switch is pressed and 
VDC OFF indicator lamp is in ON status).

The vehicle speed does not increase, when the accelerator pedal is depressed while the 
vehicle is on a 2-wheel chassis dynamometer for speedometer check.

This is not a malfunction. (When checking 
the vehicle on a chassis dynamometer, 
operate VDC OFF switch so that TCS 
function is OFF.)

• Check that there is no foreign material like iron powder or damage on inner surface of front wheel sensor

mounting hole of steering knuckle and sensor rotor. Install after cleaning when there are foreign material like
iron powder, or replace when there is a malfunction.
