Information

[Mechanical neutral]

Preparation:

1. Turn the ignition switch off. Do not start the engine with the rear steering center lock pin in the rear steering actuator. If the steering wheel is turned with the engine running, the rear steering actuator will operate and be damaged.
2. Install the rear steering center lock pin in the rear actuator.
3. Jack up the car and place the four wheels gently in the center of the turning radius gauge turntables.

Mechanical neutral Check:

• Install the toe inspection gauge (07HGJ-0010000) on the wheels.
• Read the toe inspection gauge on each wheel and be sure that the front and rear wheels are in proper alignment. (Difference in toe gauge reading between the right and left wheel is within specification)
• Mark to indicate straight ahead position of steering wheel at this time.
• Be sure to remove the rear steering center lock pin after the mechanical neutral check.

INSUFFICIENT ACTUAL REAR STEERING ACTUATOR CURRENT

POSSIBLE FAILURES

• Blown fuse
• Open in harness
• Rear actuator failure

DIAGNOSTIC PROCEDURE

• A power circuit is checked by comparing the DUTY value calculated by CPU with the actual current value. At DUTY60%, if those DUTY values stays within a colored portion of the figure for predetermined time, this DTC is confirmed.
• Predetermined time :
  Vehicle speed above 30km/h or 18.6MPH : 50ms
