Component Inspection
■ Check torque sensor
1.

Ignition "OFF".

2.

Connect Scantool to Data Link Connector(DLC).

3.

Engine "ON " and select "SCOPEMETER FUNCTION" on scantool.

4.

Measure output signal between terminal Main sensor harness connector and chassis ground.

Specification :

Fig.1) when turning steering wheel to right

Fig.2) when turning steering wheel to left

Fig.1) When turning steering wheel to right : Check whether signal voltage rises to maximum 4V based on 2.5V and main sensor signal is the same as sub sensor signal. [Main sensor - Sub sensor] < 0.75 mA .

Fig.2) When turning steering wheel to left : Check whether signal voltage descends to maximum 1V based on 2.5V and main sensor signal is the same as sub sensor signal. [Main sensor - Sub sensor] < 0.75 mA .

5.

Is torque sensor main signal within specifications?

▶ Substitute with a known-good EPS CM and check for proper operation.

▶ If the problem is corrected, replace EPS CM and then go to "Verification of Vehicle Repair" procedure.

▶ Check torque sensor for contamination, deterioration, or damage.

▶ Substitute with a known-good steering column assembly and check for proper operation.

note

Substitiuion is necessary because torque sensor is located in steering column assembly and disconnect is impossible.

▶ If the problem is corrected, replace steering column assembly and then go to "Verification of Vehicle Repair" procedure.
