Steering assistance

B3EP13KC

B3EP13LC

Supplier: KOYO.

Electric power-assisted steering ECU.

Only one ECU version, whatever the engine-type.

The electric power steering ECU is linked to the following connec-

tors:

The steering assistance is provided by the assistance motor (12), control-

led by the ECU.

Power delivered to the assistance motor (12) depends on:

- (6) Assistance motor supply.

- (13) Electric power steering ECU supply.

- (14) Control signals.

After changing the electric power steering ECU, it is necessary to

perform a configuration. (See corresponding operation).

- Speed of the vehicle.

- Torque applied on the steering wheel.

Centring the steering rack

Preliminary operation.

Raise and support the vehicle on a two-column lift.

Remove, on the RH side of the steering rack:

- Clip (1).

- Clip (2).

Release the steering rack protection gaiter.

Setting

Move the steering to full left hand lock.

Measure the dimension X.

B3EP13UC

Move the steering to full right hand lock.

Measure the dimension Y.

Calculate the dimension: L = (Y – X) : 2.

Refit:

- The steering rack protection gaiter

- New clips (1) and (2).
