Dodge Nitro. Manual — part 183

The condition that caused the symptom is currently not present. Inspect the related wiring for a
possible intermittent condition. Look for any chafed, pierced, pinched, or partially broken wires.

Refer to the ABS INTERMITTENT CONDITION.

2) CHECK STEERING ANGLE SENSOR OUTPUT

Start the engine.

Center the steering wheel.

With the scan tool, read the Steering Angle Sensor Position.

Is the Steering Angle Sensor Position within ±15°?

Yes

Go to 3).

No

Go to 8).

3) INSPECT VEHICLE, STEERING COLUMN, & INTERMEDIATE SHAFT FOR DAMAGE

Turn the ignition off.

Inspect the vehicle for damage causing tracking problems.

Inspect the steering column and intermediate shaft for damage.

Were any problems found?

Yes

Repair as necessary.

Perform ABS VERIFICATION TEST.

No

Go to 4).

4) CHECK STEERING ANGLE SENSOR INSTALLATION

NOTE:

If possible, check vehicle repair history for collision damage.

WARNING:

To avoid personal injury or death, on vehicles equipped with
airbags, disable the supplemental restraint system before attempting

Verify that the Steering Angle Sensor is properly installed.

Is the Steering Angle Sensor properly installed?

Yes

Go to 5).

No

Repair as necessary and clear offsets by initializing ECU with wheels pointing straight ahead.

Perform ABS VERIFICATION TEST.

5) INSPECT RELATED WIRING HARNESS, TERMINALS, & CONNECTORS

Check all related wiring for pinched, chafed, pierced, and partially broken wires.

Check all related connectors for broken, bent, pushed out, and corroded terminals.

Were any problems found?

Yes

Repair as necessary.

Perform ABS VERIFICATION TEST.

No

Go to 6).

6) CHECK (F202) FUSED IGNITION SWITCH OUTPUT (RUN-ACC) CIRCUIT FOR HIGH
RESISTANCE

any steering wheel, steering column, airbag, occupant classification
system, seat belt tensioner, impact sensor, or instrument panel
component diagnosis or service. Disconnect and isolate the battery
negative (ground) cable, then wait two minutes for the system
capacitor to discharge before performing further diagnosis or
service. This is the only sure way to disable the supplemental
restraint system. Failure to take the proper precautions could result
in accidental airbag deployment.

NOTE:

Proper Steering Angle Sensor installation is crucial for proper operation.

NOTE:

A low voltage condition at the Steering Angle Sensor will cause this DTC
to set.

Disconnect the Steering Angle Sensor harness connector.

Turn the ignition on.

Measure the voltage of the (F202) Fused Ignition Switch Output (Run-ACC) circuit.

Is the voltage above 11.0 volts?

Yes

Go to 7).

No

Repair the (F202) Fused Ignition Switch Output (Run-ACC) circuit for high resistance.

Perform ABS VERIFICATION TEST.

7) CHECK (Z937) GROUND CIRCUIT FOR HIGH RESISTANCE

Turn the ignition off.

Measure the resistance of the (Z937) Ground circuit between ground and the Steering Angle Sensor
harness connector.

Is the resistance below 5.0 ohms?

Yes

Replace the Steering Angle Sensor in accordance with the Service Information and clear offsets by
initializing ECU with wheels pointing straight ahead. Refer to ABS VERIFICATION TEST.

No

Repair the (Z937) Ground circuit for high resistance.

Perform ABS VERIFICATION TEST.

8) CHECK STEERING ANGLE SENSOR OUTPUT WHILE ROTATING THE STEERING
WHEEL

With the scan tool, read the Steering Angle Sensor Position while rotating the steering wheel to the right
and then to the left. The Steering Angle Sensor Position should decrease when rotating the steering wheel
to the right and increase when rotating the steering wheel to the left.

Did the steering angle change accordingly?
