1NOTE: If a system undervoltage or overvoltage DTC is set along with this
DTC, diagnose the system voltage DTC first.
NOTE: Electromagnetic (radio) interference can cause an intermittent
system malfunction by interrupting communication between the sensor
and the CAB.
NOTE: The Steering Angle Sensor is very sensitive to changes due to
alignment problems. The sensor must be recalculated using the DRBIIItif
alignment has been changed by more than 5 degrees.
Turn the ignition on.
With the DRBIIIt, erase DTCs.
Test drive the vehicle.
Using the DRBIIIt, perform the road test procedure.
With the DRBIIIt, read DTCs.
NOTE: If the ESP lamp remains illuminated after the test has completed, a
fault code will be set indicating the cause of the failure.
Does this DTC reset?All
Ye s!Go To 2
No!Go To 3
2NOTE: When the vehicle is in a turn, the ESP compares the Steering Angle
Sensor value and the speed of the inner and outer wheels to determine if the
values are plausible.
Inspect the front end and steering components for damage or misalignment.
Inspect the steering column and Steering Angle Sensor for correct mounting and
installation.
Inspect the tires and wheels to make sure that they are the correct size. All tires must
be the same size.
Inspect the left and right Wheel Speed Sensors to make sure they are connected
correctly, i.e. left harness connected to left sensor, etc.
Were any problems found?All
Ye s!Repair or replace components as necessary in accordance with the
Service Information.
No!Replace the Steering Angle Sensor in accordance with the Service
Information.

sway during turns. The bar helps to maintain a flat
attitude to the road surface.

WHEEL ALIGNMENT
DESCRIPTION
NOTE: Camber and Caster are not adjustable on
this vehicle. (TOE ONLY).
NOTE: Suspension components with rubber/ure-
thane bushings should be tightened with the vehi-
cle at normal ride height. It is important to have the
springs supporting the weight of the vehicle when
the fasteners are torqued. If springs are not at their
normal ride position, vehicle ride comfort could be
affected and premature bushing wear may occur.
Wheel alignment involves the correct positioning of
the wheels in relation to the vehicle. The positioning
is accomplished through suspension and steering
linkage adjustments. An alignment is considered
essential for efficient steering, good directional stabil-
ity and to minimize tire wear. The most important
measurements of an alignment are caster, camber
and toe (Fig. 1).
CAUTION: Never attempt to modify suspension or
steering components by heating or bending.
DIAGNOSIS AND TESTING - PRE - ALIGNMENT
INSPECTION
Before starting wheel alignment, the following
inspection and necessary corrections must be com-
pleted. Refer to Suspension and Steering System
Diagnosis Chart below for additional information.
(1) Inspect tires for size, air pressure and tread
wear.
(2) Inspect front wheel bearings for wear.
(3) Inspect front wheels for excessive radial or lat-
eral runout and balance.
(4) Inspect ball studs, linkage pivot points and
steering gear for looseness, roughness or binding.
(5) Inspect suspension components for wear and
noise.
(6) Road test the vehicle.

STANDARD PROCEDURE - TOE ADJUSTMENT
CAMBER AND CASTER ARE NOT ADJUSTABLE
(TOE ONLY)..
The wheel toe position adjustment is the final
adjustment.
(1) Start the engine and turn wheels both ways
before straightening the wheels. Secure the steering
wheel with the front wheels in the straight-ahead
position.(2) Loosen the tie rod jam nuts.
NOTE: Each front wheel should be adjusted for
one-half of the total toe position specification. This
will ensure the steering wheel will be centered
when the wheels are positioned straight-ahead.
(3) Adjust the wheel toe position by turning the
inner tie rod as necessary.

(4) Tighten the tie rod jam nut to 50 N´m (37 ft.
lbs.).
(5) Verify the specifications
(6) Turn off engine.
