YES
- Substitute with a known-good HECU/each sensor and check for proper operation. If problem is corrected, replace HECU/each sensor and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
In a case of replacing HECU, operate each sensor's calibration by scantool, including the steering angle sensor's calibration.
In a case of replacing the sensor, operate the sensor's calibration by scantool.
