1 NOTE: If a system undervoltage or overvoltage DTC is set along with this
DTC, diagnose the system voltage DTC first.
NOTE: Electromagnetic (radio) interference can cause an intermittent
system malfunction by interrupting communication between the sensor
and the CAB.
NOTE: The Steering Angle Sensor is very sensitive to changes due to
alignment problems. The sensor must be recalculated using the DRBIII" if
alignment has been changed by more than 5 degrees.
