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: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.
