Antilock Brake System
STEERING ANGLE SENSOR INSPECTION
1. Remove the column cover.
2. Measure the voltage between steering angle sensor terminal B and ground.
^
If there is any malfunction, inspect the wiring harness between steering angle sensor terminal B and battery, then repair or replace if necessary.
Standard voltage B+
3. Turn the ignition switch to the ON position, then measure the voltage between steering angle sensor terminal A and ground.
^
If there is any malfunction, inspect the wiring harness between steering angle sensor terminal A and ignition switch, then repair or replace if
necessary.
Standard voltage B+
4. Measure the voltage between steering angle sensor terminal H and the ground.
^
If there is any malfunction, inspect the wiring harness between steering angle sensor terminal H and ground point, then repair or replace if
necessary.
Standard voltage 0 V
5. Turn the ignition switch off.
6. Connect the M-MDS to the DLC-2.
7. Select the SWA_POS PID.
8. Verify the SWA_POS changes when the steering wheel is turned to the left and right.
^
If there is any malfunction, replace the steering angle sensor.
Standard
When the steering wheel is turned to the right: SWA_POS changes positively.
When the steering wheel is turned to the left: SWA_POS changes negatively.
