FAULT DIAGNOSIS ABS FAULT DIAGNOSIS
If a fault has occurred, or has been identified by ECU
self diagnostic function and ABS warning light is
illuminated. The system and components must be
checked to locate and rectify fault, using Testbook
diagnostics.
NOTE: If warning lamp has indicated a
fault in system, and no fault code has been
stored in memory, cause of fault is:
a) Failure in electrical supply
b) Bad ECU ground
c) Faulty warning light relay
d) ECU not connected
Before commencing fault diagnosis procedure
following items must be checked:
1.Inspect all exposed cables for damage or
abrasion.
2.Check ground on ABS system.
3.Battery - state of charge.
4.Check hub end-float.
5.All ABS fuses and electrical connections.
Fault rectification
1.Complete harness should be replaced if faults
are found in wiring harness.
2.DO NOT use unspecified cables or connectors,
as this could jeopardise safe function of ABS.
3.DO NOT attempt to open sealed 35 way
connector to ECU.FAULT DIAGNOSIS PROCEDURE
NOTE: If ABS warning light illuminates due
to large sensor air gap, fault will be
retained by the ECU memory. Where wheel
sensors have been pushed fully home prior to
test, The ECU will indicate a fault that has been
rectified.
NOTE: After any steering adjustment,
bearing replacement/adjustment, brake
disc replacement: Check hub end-float and
sensor clearance.
RELAYS AND FUSES ABS
The location and identification of ABS electrical relays
are given in the Electrical Troubleshooting Manual
For location and identification of ABS electrical fuses.

FAULT DIAGNOSIS FAULT - SYMPTOMS
Vibration through steering wheel
1.Check tyre pressures.
See Repair, Tyre
Pressures
2.Check condition of tyres.See Tyre Wear Chart
3.Check front wheel alignment.See STEERING,
Adjustment, Front Wheel Alignment
4.Check wheel balance.See Repair, Wheel
Balancing
NOTE: In the event that any apparent
vibration is not eliminated at this stage.
See PROPELLER SHAFTS, Fault
diagnosis, Vibration Harshness
NOTE: In the event that any apparent
vibration is not eliminated at this stage, go
to steering Fault Diagnosis, Fault -
Symptom (Steering vibration, road wheel
shimmy/wobble).
See STEERING, Fault diagnosis,
Steering Faults
NOTE: Radial ply tyres have a flexible
sidewall, which produces a sidewall bulge
making the tyre appear under-inflated.
This is a normal condition for radial ply tyres. Do
not attempt to reduce this bulge by over-inflating
the tyre.
1. Correct inflation.
2. Under-inflation.
3. Over-inflation.
4. Tread contact with road.
