5.CHECK WIRING HARNESS FOR SHORT CIRCUIT
1. Disconnect ABS actuator and electric unit (control unit) connec-
tor and wheel sensor connector of malfunction code No.
2. Check continuity between wheel sensor harness connector ter-
minals and ground.

NORMAL OPERATING CONDITION
DescriptionINFOID:0000000001731207
Symptom Result
Slight vibrations are felt on the brake pedal and the operation noises occur, when VDC, TCS or ABS is acti-
vated.
This is a normal condi-
tion due to the VDC,
TCS or ABS activation. Stopping distance is longer than that of vehicles without ABS when the vehicle drives on rough, gravel, or
snow-covered (fresh, deep snow) roads.
The brake pedal moves and generates noises, when TCS or VDC is activated due to rapid acceleration or
sharp turn.
The brake pedal vibrates and motor operation noises occur from the engine room, after the engine starts and
just after the vehicle starts.This is normal, and it is
caused by the ABS op-
eration check.
Depending on the road conditions, the driver may experience a sluggish feel. This is normal, because
TCS places the highest
priority on the optimum
traction (stability). TCS may activate momentarily if wheel speed changes when driving over location where friction coefficient
varies, when downshifting, or when fully depressing accelerator pedal.
The ABS warning lamp, VDC OFF indicator lamp and SLIP indicator lamp may turn ON when the vehicle is
subject to strong shaking or large vibration, such as when the vehicle is rotating on a turntable or located on
a ship while the engine is running. In this case, restart the
engine on a normal
road. If the normal con-
dition is restored, there
is no malfunction. At
that time, erase the self-
diagnosis memory. VDC may not operate normally or the ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp
may illuminate, when running on a special road that is extremely slanted (e.g. bank in a circuit course).
A malfunction may occur in the yaw rate/side/decel G sensor system, when the vehicle turns sharply, such
as during a spin turn, axle turn, or drift driving, while the VDC function is off (VDC OFF indicator lamp illumi-
nated).
The vehicle speed will not increase even though the accelerator pedal is depressed, when inspecting the
speedometer on a 2-wheel chassis dynamometer. Normal (Deactivate the
VDC/TCS function be-
fore performing an in-
spection on a chassis
dynamometer.)
VDC OFF indicator lamp and SLIP indicator lamp may simultaneously turn on when low tire pressure warn-
ing lamp turns on.This is not a VDC sys-
tem error but results
from characteristic
change of tire.

DIAGNOSIS AND REPAIR WORKFLOW
 Malfunctions are declared as either present or stored (depending on whether they appeared in a certain con-
text and have disappeared since, or whether they remain present but have not been diagnosed within the
current context).
 The present or stored status of malfunctions should be taken into consideration when the diagnostic tool is
used following the + after ignition supply being switched on (without acting on the system components).
 For a present malfunction, apply the procedure described in the Interpretation of malfunction section.
 For a stored malfunction, note the malfunctions displayed and apply the instructions in the Notes section.
 If the malfunction is confirmed when the instructions in the Notes section are applied, the malfunction is
present. Deal with the malfunction
 If the malfunction is not confirmed, check:
- the electrical lines which correspond to the malfunction,
- the connectors for these lines (for oxidation, bent pins, etc),
- the condition of the wires (insulation has melted or been cut, abrasions),
- the resistance of the component detected as malfunction.
Conformity Check
 The aim of the conformity check is to check data that does not produce a malfunction on the diagnostic tool
because the data is inconsistent. Therefore, this phase is used to:
- carry out malfunction finding on malfunctions that do not have a malfunction display, and which may corre-
spond to a customer complaint.
- check that the system is operating correctly and that there is no risk of a malfunction recurring after repairs.
 This section gives the malfunction finding procedures for statuses and parameters and the conditions for
checking them.
 If a status is not behaving normally or a parameter is outside the permitted tolerance values, consult the cor-
responding malfunction finding page.
Customer Complaints - Malfunction finding chart
If the test with the diagnostic tool is OK but the customer complaint is still present, the malfunction should be
processed by customer complaint.
NOTE:
A synopsis of the general procedure to follow is provided on the preceding page in the form of a flow
chart.
Malfunction Finding Procedure (Wiring Check)
Diagnostics malfunctions
Removing the connectors and/or handling the wirings may temporarily remove the origin of a DTC. The mea-
surements of the electrical voltages, resistance and insulation are generally correct, especially when the DTC
is not present at the time of the analysis (stored DTC).
Visual Check
Look for impacts under the bonnet and in the passenger compartment.
Perform a careful check of the protections, insulation and correct running of wirings.
Look for traces of oxidation.
Tactile Check
While manipulating the wirings, use the diagnostic tool to detect a change in DTC status from “stored” to
“present”.
Ensure that the connectors are correctly engaged.
Apply light stresses to the connectors.
Gently manipulate the wiring harness.
If a change of status occurs, try to isolate the origin of the incident.
Inspection of each component
Disconnect the connectors and check the appearance of the clips and blades and their crimping (no crimping
on the insulating part).
Check that the clips and blades are properly engaged in the receptacles.
Ensure that there is no rebounding of clips or blades at the time of connection.
Check the contact pressure of the clips using a suitable model blade.
Resistance Control
Test the continuity of the lines in their entirety, then section by section.
Try to create a short-circuit to earth, on the + 12 V or with another wire.
If a DTC is detected, repair or replace the wiring.
