Important: For best calibration performance, it is recommended
that the front wheels are aligned to the specification. Refer to
Wheel Alignment Specifications
.
The steering angle sensor does not require centering often. Centering of the
steering angle sensor might be required after certain service procedures are performed.
Some of these procedures are as follows:
| • | Steering gear replacement |
| • | Steering column replacement |
| • | Steering angle sensor replacement |
| • | Intermediate shaft replacement |
| • | Electronic brake control module (EBCM) replacement |
| • | Collision or other physical damage |
The steering angle sensor centering procedure can be completed with a scan tool
using the following steps:
- Using the steering wheel, align the front wheels forward.
- Set the transmission in the PARK position.
- Turn the ignition switch ON, with the engine OFF.
- Clear any DTCs that may be set.
- Select Steering Angle Sensor Centering in the EBCM Special Functions list.
- Following the directions given on the scan tool, calibrate the steering
angle sensor.
- Make sure the steering angle sensor reads 0° in the straight ahead
position.
- Road test the vehicle and note the steering wheel position when the vehicle
is travelling in the straight-ahead direction.
