3. If the vehicle needs to be driven in order to perform a DPF service, ALWAYS have
a second person help you. One person should drive the vehicle while the other
person observes the screen on the Tool. Trying to drive and observe the Scan Tool
at the same time is dangerous, and could cause a serious traffic accident.
Steering Angle Sensor (SAS) Service
Steering Angle Sensor Calibration permanently stores the current steering wheel position
as the straight-ahead position in the steering angle sensor EEPROM. Therefore, the front
wheels and the steering wheel must be set exactly to the straight-ahead position before
calibration. In addition, the vehicle identification number is also read from the instrument
cluster and stored permanently in the steering angle sensor EEPROM. On successful
completion of calibration, the steering angle sensor fault memory is automatically cleared.
Calibration must always be carried out after the following operations:
Steering wheel replacement
Steering angle sensor replacement
Any maintenance that involves opening the connector hub from the steering angle
sensor to the column
Any maintenance or repair work on the steering linkage, steering gear or other
related mechanism
Wheel alignment or wheel track adjustment
Accident repairs where damage to the steering angle sensor or assembly, or any
part of the steering system may have occurred
NOTE
1. AUTEL accepts no responsibility for any accident or injury arising from servicing the
SAS system. When interpreting DTCs retrieved from the vehicle, always follow the
manufacturer
’s recommendation for repair.
2. Before starting the procedure, make sure the vehicle has ESC. Look for the button
on dash.
Throttle Match Service
Initialize the actuator of the vehicle throttle to make the ECU learned value return to the
initial status so as to control the intake air volume more accurately.
