caution | After the next operation has been completed, carry out the following two operations:- Alignment adjustment <Front>
- Steering wheel and steering wheel sensor (column switch assembly) replacement, removal, installation
- EPS-ECU replacement
- Steering column shaft assembly replacement
- Reset the calibrated value of the torque sensor neutral position stored in EPS-ECU.
- Update the steering wheel neutral position stored in the EPS-ECU.
|
caution | - Before performing the calibration, check if the steering wheel sensor-related DTC is set in ASC-ECU.
- When the DTCs other than C1518 and C1519 are set, carry out inspection according to each troubleshooting procedure.
