Steering Angle Sensor Centering

Steering angle sensor does not require centering often. Centering of 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
• ABS controller replacement
• Collision or other physical damage
• Engine cradle replacement

The steering angle sensor centering procedure can be manually accomplished by the following steps:

1. Using steering wheel, set wheels straight ahead. Set transmission in PARK position. Verify brake pedal switch and TRACTION CONTROL switch are operating properly. Set park brake on to inhibit Daytime Running Lights (DRL).
2. Turn ignition on, engine off. After 10 seconds, instrument cluster lights that are on are as follows: SERVICE ENGINE SOON, SECURITY, seat belts and BRAKE.
NOTE: Steering angle sensor will be uncentered before it is centered. Steps 3 through 6 will uncenter steering angle sensor. Technician must become familiar with these steps because they have to be performed within a set amount of time. If they are not performed within time period called out by individual step, uncentering of steering angle sensor will not be performed.
3. Press TRACTION CONTROL switch 3 times within 5 seconds. TRAC OFF light is on.
4. Using scan tool with ABS data list selected, press brake pedal firmly and hold to achieve 725 psi. LOW TRAC light turns on and TRAC OFF light remains on.
5. Press TRACTION CONTROL switch 3 times within 5 seconds. LOW TRAC light flashes and TRAC OFF light goes off.
6. Release brake pedal within 5 seconds. TRAC OFF light is on, LOW TRAC light is off and PCS light is flashing.
7. Uncentering of steering angle sensor is complete.
NOTE: Steering angle sensor will now be centered. Steps 8 and 9 will center steering angle sensor. Technician must become familiar with these steps because they have to be performed within a set amount of time. If they are not performed within time period called out by individual step, centering of steering angle sensor will not be performed.
8. Press TRACTION CONTROL switch 3 times within 5 seconds. LOW TRAC light is on. TRAC OFF light is on.
9. Press TRACTION CONTROL switch 3 times within 5 seconds. LOW TRAC light is off, TRAC OFF light is off, PCS light is off and SERVICE VEHICLE SOON light will come ON and then go OFF.
10. Centering of steering angle sensor is complete.
