The DTC is cleared |
There is no malfunction if this DTC is not output again after clearing the DTC and torque sensor calibration value, and performing zero point calibration. |
CAUTION / NOTICE / HINT
NOTICE:
If the rack and pinion power steering gear assembly has been replaced, perform assist map writing and torque sensor zero point calibration.
