Replacing the combination sensor
After replacing the combined sensor, be sure to delete the correction information from the computer memory using command RZ008 «Lateral acceleration sensor programming correction».
Steering Angle Sensor Replacement
Two types of steering angle sensors can be installed on the LAGUNA II.
- steering angle sensor (designed for several full revolutions) installed on a LAGUNA II vehicle.
- - steering wheel angle sensor (for one full turn) installed on a LAGUNA II vehicle.
The installation of a sensor designed for several full revolutions is determined with the wheels installed for driving in a straight line, by the presence of a yellow plate opposite the viewing window of the sensor (when rotated, the background turns blue).
When installing a sensor designed for one full turn, nothing appears in the sensor window (no color change when turning the steering wheel).
Note. After replacing the steering wheel angle sensor, be sure to clear the correction information from the ECU memory using command RZ007 «Steering wheel angle sensor programming correction-.
