Thanks Dan
Thanks Dan
Excessive Time to Center Steering.
"Condition 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 kph(25mph) or greater for longer than 10 minutes, DTC 1283 will be set."

A friend of mine has been dealing with this same 1283 code for a while but he's proceeding carefully as it can get expensive quickly yanking components and replacing them just to see if they are the problem. We spent some time diagnosing that, a 1225 code and a 1288 code. Playing with the EBTCM attached to the ABS unit in front of the motor and with one of the wheel speed sensors eliminated the 1225 code but the other two persist. I dug into the manual to study the diagnostics of the remaining codes (the 1288 appears about 50% of the time the 1283 does) and discovered the 1283 code is most like one of three modules - the yaw rate sensor behind the A/C head unit, the lateral accelerometer under the passenger seat or the EBTCM unit itself (at least $900 from the dealer! 
). I can send you the 1283 diagnostic if you like.
The 1288 is related to a malfunctioning steering wheel position sensor.

If I recall correctly, the 1283 code (none AH cars) and 1286 (AH) codes are similar. This happens if you disconnect the steering shaft or redo the suspension after lowering a car....especially for road race or autoX. Two ways to check.....with a TECH 2, measure the voltage of the steering sensor with the steering wheel centered. IF the voltage is 2.4, its the yaw sensor, it reads 0.24 or 4.9V turn the wheel until it says 2.4-2.5 V. W/O a Tech2 use a VOM and disconnect the steering connector at the firewall. Hard place to get to...then measure the voltage of the middle light blue wire. Once you find the steering center mark it with tape and realign the wheels to the steering wheel.
