Get this after putting rack back in. The steering wheel was turned during the the reinstall,didnt know how much so had to turn from L stop to R stop to find center. So how screwed am I.

Have you driven it yet? Usually the lights goes out quickly WHILE driving. Just a warm-up message.
If you have a real issue PM Bill Curlee he usually has answers to many of our dilemmas.

 

Yes I have driven the car and did not turn off, t/c still worked I spun the tires and system was activated. I am pulling battery cable to see if will reset.

 

You should use the DIC to see if there are any ABS system codes.

NO codes until today a c1283. I think the problem is in the swps. The steering wheel was turned wnen it was unhooked from the rack. I had to turn from l stop to r stop to insure the wheel was in the center. Is there any way to re position the swps or will it have to be replaced. My 3 book manual set is on its way.

DTC C1283 Excessive Time to Center Steering





Circuit Description

Steer angle centering is the process by which the EBTCM calibrates the steering sensor output so that it reads zero when the steering wheel is centered. The initial steering wheel center position is calculated after driving 10 Km/h (6 mph) for more than 10 seconds in a straight line on a fairly level surface. The EBTCM uses the Yaw Rate Sensor, Lateral Accelerometer and Wheel Speed Sensors to tell if the vehicle is moving in a straight line. This centering routine is necessary to compensate for wear in the steering and suspension. Wear in the steering and suspension can result in a change in the relationship between the steering wheel and the front wheels. By running the centering routine the EBTCM can compensate for these changes by changing the digital and analog center position.
Conditions for Setting the DTC

The initial steering wheel center position will be determined quickly unless there is a large offset in the yaw sensor or lateral accelerometer output. When this happens the system will believe the steering is far off center even though the vehicle is being driven in a straight line. Under this condition and with a continuous vehicle speed of 40 Km/h (25 mph) or greater for longer than 10 minutes, DTC C1283 will be set.
Action Taken When the DTC Sets




ABS and TCS remain enabled, Active Handling is disabled.

• Indicators that turn on: Car Icon (TCS indicator)
• Messages displayed on the DIC: Service Active HNDLG Service Vehicle Soon

Conditions for Clearing the DTC

• Condition for DTC is no longer present and scan tool clear DTC function is used.
• Fifty ignition cycles have passed with no DTCs detected.

Diagnostic Aids

• It is very important to check the vehicle for proper alignment. The car should not pull in either direction while driving straight on a flat surface.
• It is very important to find out from the driver when the code was set (when the SERVICE ACTIVE HNDLG message was activated). This information may help to duplicate the failure.
• It is very important that a thorough inspection of the wiring and connectors be performed. Failure to carefully and fully inspect wiring and connectors may result in misdiagnosis, causing part replacement with reappearance of the malfunction. Check connector C102 RH side rear of engine compart for water intrusion or missing plugs, and that the connector is oriented horizontal to prevent water intrusion.
• An intermittent malfunction is most likely caused by a poor connection, rubbed through wire insulation, or a wire that is broken inside the insulation. Refer to Testing for Electrical Intermittents in Wiring Systems.
• The Snapshot function on the scan tool may help in finding an intermittent DTC C1283.
