Wiring Diagram










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 indicated, together?
YES -
Go to applicable DTC troubleshooting.
NO -
Go to Step 3.

3. Torque sensor power supply voltage check

With ignition switch turned OFF, disconnect torque sensor connector.
Check for voltage between "E31-3" ("GRN" wire) terminal and body ground with ignition switch ON.

Is it approx. 9 V?
YES -
Go to Step 4.
NO -
Go to Step 5.

4. Torque sensor power supply voltage check

With ignition switch turned OFF, connect torque sensor connector.
Check for voltage between "E11-8" ("GRN" wire) terminal and body ground with ignition switch ON.

Is it approx. 9 V?
YES -
Substitute a known-good P/S control module and recheck.
NO -
Replace steering gear case.

5. Torque sensor power supply circuit check

Check that torque sensor power supply circuit is as follows.
- Insulation resistance of wire harness is infinity between "Torque sensor power supply circuit" terminal and each other terminal at torque sensor connector.
- Wiring harness resistance of "Torque sensor power supply circuit" is less than 1 ohms.
- Insulation between "Torque sensor power supply circuit" and vehicle body ground is infinity.

Is circuit in good condition?
YES -
Replace P/S control module.
NO -
Repair or replace defective circuit.
