DTC

C200B:25/C200B:62

Torque sensor

DETECTION CONDITION

•  C200B:25

―  Out-of-specification signal modulation is detected from torque sensor

•  C200B:62

―  Difference occurs between signals 1 and 2 from torque sensor

POSSIBLE CAUSE

•  Torque sensor malfunction

•  EPS control module malfunction

Diagnostic Procedure

Step

Inspection

Action

1

INSPECT TORQUE SENSOR USING M-MDS

•  Connect the M-MDS to the DLC-2.

•  Switch the ignition to ON (engine OFF).

•  Access “SS_TRQ1” and ”SS_TRQ2” PIDs.
(See ELECTRIC POWER STEERING (EPS) ON-BOARD DIAGNOSIS.)

•  Verify that the data monitor value changes when the steering wheel is turned.

―  Left: 0—positive

―  Right: 0— negative

•  Do the torque sensor signal values change in the same way?

Yes

Go to the next step.

No

Replace the steering gear and linkage (torque sensor), then go to the next step.

(See STEERING GEAR AND LINKAGE REMOVAL/INSTALLATION [L.H.D.].)

(See STEERING GEAR AND LINKAGE REMOVAL/INSTALLATION [R.H.D.].)

2

VERIFY THAT SAME DTC IS NOT PRESENT

•  Clear the DTC from the memory.
(See ELECTRIC POWER STEERING (EPS) ON-BOARD DIAGNOSIS.)

•  Is the same DTC present?
(See ELECTRIC POWER STEERING (EPS) ON-BOARD DIAGNOSIS.)

Yes

Repeat the inspection from Step 1.

If the malfunction recurs, replace the EPS control module.

(See EPS CONTROL MODULE REMOVAL/INSTALLATION.)

No

Go to the next step.

3

VERIFY THAT NO OTHER DTCs ARE PRESENT

•  Are any other DTCs output?
(See ELECTRIC POWER STEERING (EPS) ON-BOARD DIAGNOSIS.)

Yes

Go to the applicable DTC inspection.

(See ELECTRIC POWER STEERING (EPS) ON-BOARD DIAGNOSIS.)

No

DTC troubleshooting completed.
