ELECTRIC POWER STEERING REPAIRING


The steering warning light will illuminate during the light check cycle and when the EPS is in assist off mode. The steering warning light will not illuminate during limited assist operation. By turning the steering wheel all the way to one side, it will cause the EPS system to provide the maximum amount of current to the EPS motor. If the steering wheel is then held in this position for an extended period of time, the system will go into protection mode so the motor doesn’t overheat. If this occurs the EPS system will limit the amount of current to the motor and reduce the level of power assist. If it senses high system temperature the overload protection mode will enable. If a sensor or other another component in the EPS system fails, the self-diagnostics should detect the fault, set a code and disable power-assist. Though power steering hoses and fluid were eliminated, there are still going to be other parts that malfunction over time. Most system malfunctions present problems such as:

  • Heavy steering: Check torque sensor, power steering motor, speed sensors, powers steering ECU, and ECU source voltage.
  • Uneven steering between right and left: Check calibration of torque sensor (built into steering column), power steering motor, power steering ECU or wheel alignment.
  • Steering effort doesn’t decrease while driving: Check torque sensor, power steering motor, power steering ECU.
  • Knocking when turning steering wheel: Steering intermediate shaft, ball joint.
  • Noise or vibration in steering wheel: Check power steering gear, steering column.
  • Squeaking – Power steering motor.
Torque sensor testing
  • 1. Measure the resistance between torque sensor connector terminals 1 and 2, and 2 and 3.
  • 2. If there is any malfunction, replace the steering gear and linkage.
  • 3. The torque sensor zero point should be calibrated whenever you remove and replace the steering column assembly (containing the torque sensor), power steering ECU assembly, steering wheel steering gear assembly, and if a difference is felt in steering effort between right and left.
Check steering wheel looseness, play -
  • 1. Move the steering wheel toward the shaft and in four right angle directions to inspect for looseness and play.
  • 2. If there is any malfunction, inspect the following, and repair or replace the applicable part.
Steering wheel effort -
  • Steering effort also varies per road conditions and type of surface the vehicle is on.
  • 1. Verify that the equipped tire size and tire air pressure is as specified.
  • 2. With the vehicle on a hard, level surface, put the wheels in the straight-ahead position.
  • 3. (Check proper procedures before working on the air bag system). Remove the air bag module.
  • 4. Start the engine and idle it.
  • 5. Verify that the EPS warning light does not illuminate.
  • 6. Inspect the steering wheel effort using a torque wrench. If it exceeds specifications, adjust the steering gear and, as needed, linkage.
    Check steering shaft
  • 1. Inspect the column bearing for excessive play and damage.
  • 2. Verify that the measurement of the steering shaft is within specification. If not within the specification, replace the steering shaft component.
  • Specification: 508.5 mm {20.02 in}
  • 3. Check that the tilt lever moves smoothly from the lock to the unlock position.
  • 4. Verify that the steering shaft is fixed firmly when the tilt lever is locked.
  • 5. If there is any malfunction, replace the steering shaft.
    Check EPS motor power supply for open
  • 1. Disconnect the battery positive terminal.
  • 2. Inspect for continuity between EPS control module terminal and battery positive terminal.
  • 3. Check for continuity.
    Check if malfunction is caused by a bad connection of the EPS control module
  • 1. Turn the ignition switch off.
  • 2. Inspect connection of the EPS control module and wiring harness.
  • 3. Disconnect the EPS control module connector.
  • 4. Check if malfunction is caused by a bent or poorly connected EPS control module connector pin.
  • 5. Is the connection and pin of connector and wiring harness normal?
