Fail-Safe FunctionNFS000OM
VDC/TCS SYSTEM
In case of malfunction in the VDC/TCS system, VDC OFF indicator lamp and SLIP indicator lamp are turned
on, and the condition of vehicle is the same as the condition of vehicles without VDC/TCS system. In case of
malfunction in the VDC/TCS system, the ABS control continues to operate normally without VDC/TCS control.
CAUTION:
If the fail-safe function is activated, then perform the self-diagnosis for VDC/TCS/ABS control system.
ABS, EBD SYSTEM
In case of electrical malfunctions with the ABS, ABS warning lamp, VDC OFF indicator lamp, SLIP indicator
lamp will turn on. In case of electrical malfunctions with the EBD, brake warning lamp, ABS warning lamp,
VDC OFF indicator lamp and SLIP indicator lamp will turn on. Simultaneously, the VDC/TCS/ABS become one
of the following conditions of the fail-safe function.
For malfunction of ABS, only the EBD is activated and the condition of vehicle is the same condition of
vehicles without TCS/ABS system.
NOTE:
ABS self-diagnosis sound may be heard. That is a normal condition because a self-diagnosis for “Ignition
switch ON” and “The first starting” are being performed.
For malfunction of EBD, EBD and ABS become inoperative, and the condition of vehicle is the same as
the condition of vehicles without TCS/ABS, EBD system.
How to Proceed with DiagnosisNFS000NB
BASIC CONCEPT
Most important point to perform diagnosis is to understand systems (control and mechanism) in vehicle
thoroughly.
It is also important to clarify customer complaints before inspec-
tion.
First of all, reproduce symptom, and understand it fully.
Ask customer about his/her complaints carefully. In some cases,
it will be necessary to check symptom by driving vehicle with
customer.
NOTE:
Customers are not professionals. Do not assume “maybe cus-
tomer means...” or “maybe customer mentioned this symptom”.
It is essential to check symptoms right from beginning in order to
repair a malfunction completely.
For an intermittent malfunction, it is important to reproduce
symptom based on interview with customer and past examples.
Do not perform inspection on ad hoc basis. Most intermittent
malfunctions are caused by poor contacts. In this case, it will be
effective to shake suspected harness or connector by hand.
When repairs are performed without any symptom check, no
one can judge if malfunction has actually been eliminated.
After diagnosis, make sure to perform “erase memory”. Refer to
BRC-25, "
Self-Diagnosis" .
For an intermittent malfunction, move harness or harness con-
nector by hand to check poor contact or false open circuit.
Always read “GI General Information” to confirm general precautions. Refer to GI-4, "General Precau-
tions" .
