Meritor WABCO Maintenance Manual MM-0112 (Revised 05-13)

Figure 9.15

Tip: The vehicle MUST come to a complete stop before starting

the steering ratio calculation and turning the steering wheel

360 degrees for the first time.

Once steering wheel is turned one revolution in either direction (360

degrees) accelerate slowly until 12 mph (19 kph) is reached.

Continue driving in a circle until the screen automatically changes to

inform the steering ratio is being calculated. Maintain the vehicle

speed and conditions (approximately 8 seconds) until ATC lamp

turns off.

The screen will automatically change to the next portion of the

procedure. Figure 9.16.

Figure 9.16

Tip: The vehicle does not have to come to a complete stop

before turning the steering wheel 360 degrees in the other

direction but it is recommended to make sure wheels are in

the straight position before making the turn.

Turn the steering wheel 360 degrees in the opposite direction and

repeat the driving conditions. The ATC lamp will start blinking when

the required conditions are met. Keep driving in those conditions

(approximately 8 seconds) until the lamp turns off.

The screen will automatically change to show ESC End of the Line

data and ratios. Figure 9.17.

Make sure to stop the vehicle once steering ratio calculation has

been completed.

NOTE: The circle driving (Calculation of Steering Ratio) can be done

in segments as the ECU will accumulate the information until the

desired distance is reached, but must be done within the same

ignition cycle. The calibration requires driving in both directions with

the steering wheel rotated 360 degrees.
