Inspect the related harness and connectors.
Look for any chafed, pierced, pinched, or partially broken wires.
Look for broken, bent, pushed out, or corroded terminals.
Inspect the tires and wheels to make sure that they are the correct size. All tires must
be the same size.
Inspect the steering column and Steering Angle Sensor for correct mounting and
installation.
Inspect the front end and steering components for damage or misalignment.
Were any problems found?

All

Yes

→ Repair as necessary.

No

→ Test Complete.

TEST

ACTION

APPLICABILITY

1

NOTE: 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 DRBIII

t if

alignment has been changed by more than 5 degrees.
Turn the ignition on.
With the DRBIII

t, erase DTCs.

Test drive the vehicle.
Using the DRBIII

t, perform the road test procedure.

With the DRBIII

t, 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

Yes

→ Go To 2

No

→ Go To 3

NOTE: 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

Yes

→ Repair or replace components as necessary in accordance with the

Service Information.

No

→ Replace the Steering Angle Sensor in accordance with the Service

Information.
