If DTC CONFIRMATION PROCEDURE has been previously conducted, always turn ignition switch OFF and wait at least 10 seconds before conducting the next test.
>> GO TO 2.
2.DTC REPRODUCTION PROCEDURE
With CONSULT
Turn the ignition switch OFF to ON.
Perform EPS self-diagnosis.
Is DTC “C1604” detected? YES >> Proceed to diagnosis procedure. Refer to STC-25, "Diagnosis Procedure".
NO >> Inspection End.
Diagnosis Procedure
Regarding Wiring Diagram information, refer to STC-15, "Wiring Diagram".
1.Check torque sensor power supply circuit
Turn ignition switch ON.
Check voltage between EPS control unit harness connector terminals and ground.
CAUTION:
Steering wheel is neutral position. (There is no steering force.)

Is the inspection result normal? YES >> GO TO 2.
NO >> Perform the trouble diagnosis for battery power supply circuit. Refer to STC-22, "Diagnosis Procedure".
2.Check torque sensor ground circuit
Turn ignition switch OFF.
Check continuity between eps control unit harness connector terminal and ground.
Caution:
Steering wheel is neutral position. (There is no steering force.)

Is the inspection result normal? Yes >> go to 3.
No >> repair open circuit or short to ground or short to power in harness or connectors.
3.Check torque sensor signal
Turn ignition switch off to on.
Check voltage between eps control unit harness connector terminal and ground.
Caution:
Steering wheel is neutral position. (There is no steering force.)

Start the engine.
Check voltage between EPS control unit harness connector terminal and ground.
CAUTION:
Steering wheel is right or left turn.

Is the inspection result normal? Yes >> go to 4.
No >> torque sensor is malfunction. Replace steering column assembly. Refer to st-12, "removal and installation".
4.Check connector
