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 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.
