TROUBLE DIAGNOSIS
PFP:00004
Fail-Safe Function
NFS000LE
VDC/TCS SYSTEM
In case of malfunction with TCS, the VDC OFF indicator lamp and SLIP indicator lamp are turned on, and the
condition of the vehicle is the same as the condition of vehicles without VDC/TCS system. In case of malfunc-
tion with TCS, 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 sys-
tem.
ABS, EBD SYSTEM
In case of electrical malfunction with the ABS, the ABS warning lamp, VDC OFF indicator lamp and SLIP indi-
cator lamp will turn on. In case of electrical malfunction 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 ABS malfunction, only the EBD is activated and the condition of the 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 EBD malfunction, the EBD and ABS become inoperative, and the condition of the vehicle is the same
as the condition of vehicles without VDC/TCS/ABS, EBD system.
How to Perform Trouble Diagnosis for Quick and Accurate Repair
NFS000GD
INTRODUCTION
●
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
●
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
