DTC 72: Steering Angle Sensor
- Check for DTCs with the HDS.
Are DTCs 91 or 92 indicated with DTC 72?
YES -Troubleshoot DTCs 91 or 92 and recheck.
NO -Go to step 2.
- Put the vehicle on a level surface, and center the steering wheel spokes.
- Check the STEERING ANGLE in the VSA DATA LIST with the HDS.
With the steering wheel in the straight ahead position, is STEERING ANGLE within ±5°?
YES -Go to step 4.
NO -Check for installation of the steering angle sensor. If installation is good, do the steering angle sensor center point writing.
- Check the wheel alignment (see WHEEL ALIGNMENT
).
Is the wheel alignment within the specification?
YES -Go to step 5.
NO -Make sure the suspension is not modified, and adjust the wheel alignment correctly, and recheck by test-driving.
- Clear the DTCs with the HDS (see HOW TO RETRIEVE DTCS ).
- Turn the ignition switch OFF, then disconnect the HDS.
- Test-drive the vehicle around a number of corners.
- Connect the HDS, and check for DTCs with the HDS (see HOW TO RETRIEVE DTCS
).
Does the VSA indicator come on, and is DTC 72 indicated?
YES -Replace the VSA modulator-control unit (see VSA MODULATOR-CONTROL UNIT REMOVAL AND INSTALLATION ).
NO -Intermittent failure; the most probable cause is that the vehicle has driven on an extremely sloped road. The system is OK at this time.
