2002 Lexus LS430: tilt..the steering wheel..adjustment..manually

This answer was rated:

I have a 2002 Lexus LS430 that has the tilt and telescopic feature on the steering wheel.   It would always adjust the steering wheel up out of the way when the key turned off and also had a manual adjustment on the side of the steering columm.   The telescopic part still works but the tilt will no longer work, either when the key is turned off or when attempting manually to adjust.   Any suggestions please?

Thanks for using Just Answer. I would be glad to assist you.

 

There is either a problem in the tilt circuit or the steering ECU. Please refer to the diagnostic information below:

The ECU provided both +B and ground for the tilt motor. Reserving polarity of the applied voltage reverses the motor.
