TROUBLE DIAGNOSIS (FOR TROUBLE NOT INDICATED BY ON BOARD DIAG-
NOSTIC SYSTEM)
This section describes trouble diagnosis of P/S system parts whose trouble is not indicated by the on-board
diagnostic system (self-diagnostic function).
When DTC No.12 is indicated by the on-board diagnostic system (self-diagnosis function) and assuredly those
steering basic parts as described in “DIAGNOSIS TABLE” in Section 3 are all in good condition, check the fol-
lowing power steering system parts which may be a possible cause for each symptom of the steering.
Condition Possible Cause Correction
Steering wheel feels
heavy (Perform
STEERING FORCE
INSPECTION before
diagnosis.)Steering wheel installed improperly (twisted) Install steering wheel correctly.
Poor performance of torque sensor Check torque sensor. Refer to
“TORQUE SENSOR”.
Poor performance of motor and clutch Check motor and clutch. Refer to
“MOTOR AND CLUTCH”.
Faulty steering column Replace.
Poor performance of VSS Check VSS. Refer to Section 6E.
Vehicle pulls to one
side during straight
drivingPoor performance of torque sensor Check torque sensor. Refer to
“TORQUE SENSOR”.
Poor recovery from
turnsPoor performance of torque sensor Check torque sensor. Refer to
“TORQUE SENSOR”.
Faulty steering column Replace.
