DTC Detecting Condition and Trouble Area






DTC Troubleshooting



1.
Was "EPS System Check" performed?
YES
Go to Step 2.
NO
Go to EPS System Check:Electric Type.

2. DTC check

Is DTC C1153 or C1116 indicated, together?
YES
Go to applicable troubleshooting.
NO
Go to Step 3.

3. Torque sensor signal circuit check

With ignition switch turned OFF, disconnect torque sensor connector.
Check for voltage between following terminal with ignition switch ON.
- "E11-18" ("YEL" wire) terminal and body ground
- "E11-10" ("WHT" wire) terminal and body ground

Is it about 0 V?
YES
Go to Step 4.
NO
Torque sensor signal circuit is shorted to other circuit.

4. Torque sensor circuit check

Disconnect P/S control module connector.
Check that torque sensor signal circuit is as follows.
- Insulation resistance of wire harness is infinity between "Torque sensor signal circuit" terminal and other terminal at torque sensor connector.
- Wiring harness resistance of "Torque sensor signal circuit" is less than 1 ohms.
- Insulation resistance between "Torque sensor signal circuit" and vehicle body ground is infinity.

Is circuit in good condition?
YES
Go to Step 5.
NO
Repair or replace defective circuit.

5. Torque sensor check

Connect connectors to P/S control module and torque sensor with ignition switch turned OFF.
Check torque sensor out put voltage referring to Torque Sensor and Its Circuit Inspection Torque Sensor and Its Circuit Inspection:Electric Type.

Is torque sensor in good condition?
YES
Substitute a known-good P/S control module and recheck.
NO
Go to Step 6.

6. P/S control module resistance check

With ignition switch turned OFF, disconnect torque sensor connector.
Check for resistance between following terminal with ignition switch ON.
- "E11-18" ("YEL" wire) terminal and body ground
- "E11-10" ("WHT" wire) terminal and body ground

Is it about 1 kohms?
YES
Replace steering gear case.
NO
Replace P/S control module.
