EXHAUST THROTTLE VALVE CALIBRATION
•
Slacken the exhaust throttle valve ca-
ble tension.
•
From the Adjustable parameters
screen, use the diagnostic instrument
to select: Acquire exhaust valve zero
position
•
After pressing the send button for zero
research, stop the vehicle and leave
the key in OFF.
•
Using the specific adjuster screw, ten-
sion the upper cable, leaving approx.
1.8 mm (0.07 in) between the retainer
and opening travel limit (4) of the valve
(1). Using the specific adjuster screw,
tension the lower cable so it has the
same tension as the upper cable.
•
Tightening the lower cable will proba-
bly have caused the travel limit to shift:
repeat the procedure until the correct
position is obtained.
•
Using the diagnostic tool, from the Adjustable parameters screen, select:
Exhaust exhaust valve self-acquisition, which acquires the opening travel limit (4) (valve open) and the
closing travel limit (3) (valve closed).
During both normal operation and the self-cleaning cycle, the valve will only move within this range and
without reaching the mechanical end stops, to prevent strain to the electric motor.
