Steering Angle Sensor: Programming and Relearning
Steering Angle Signal Initialization Procedure
STEERING ANGLE SIGNAL INITIALIZATION PROCEDURE
Warning
^
If the initialization procedure of the steering angle signal is not completed, the DSC will not operate properly and may cause an accident.
Therefore, always perform initialization of the DSC HU/CM steering angle signal to ensure proper DSC operation when any of the
following items are performed.
-
Steering angle sensor replacement
-
DSC HU/CM replacement
1. Inspect the wheel alignment and inflation pressure.
^
If there is any malfunction, adjust the applicable part.
2. Park the vehicle on level ground.
3. Turn the ignition switch off.
4. Connect the M-MDS to the DLC-2.
5. After the vehicle is identified, select the following items from the initialization screen of the M-MDS.
^
When using the IDS (laptop PC)
1. Select "Chassis".
2. Select "ABS/DSC".
3. Select "Sensor Initialization".
^
When using the PDS (Pocket PC)
1. Select "All Tests and Calibrations".
2. Select "Sensor Initialization".
6. Perform the initialization procedure according to the directions on the screen.
7. Drive the vehicle forward.
8. After 5 min of driving, verify that the DSC system is normal.
Steering Angle Sensor Initialization Procedure
STEERING ANGLE SENSOR INITIALIZATION PROCEDURE
Warning
^
Unless the initialization procedure of the steering angle sensor is completed, the DSC will not operate, causing an unexpected accident.
Therefore, always perform the initialization procedure to ensure DSC operation if the power supply to the steering angle sensor has been
cut off due to disconnection of the steering angle sensor connector or negative battery cable, or any other cause.
Note
^
The initialization value of the steering angle sensor is stored using the battery power supply. Therefore, the battery power supply of the steering
angle sensor is cut and the stored initialization value is cleared when any of the following items are performed.
-
Negative battery cable disconnection
-
Steering angle sensor connector disconnection
-
Fuse (ROOM 15A) removal
-
Wiring harness disconnection between battery and steering angle sensor connector
1. Inspect the wheel alignment, inflation pressure, and the installation condition of the steering wheel.
^
If there is any malfunction, adjust the applicable part.
2. Connect the negative battery cable.
