ADAPTED RANGES L3
Range: __________________________________________________________ ON/OFF
Used on ME20 systems. These parameters indicate whether the engine and transmission
control modules are working together to optimize engine speed and torque for any one given
driving condition.
ADJUST. CAMSHAFT TIMING SOLENOID
Range: __________________________________________________________ ON/OFF
Used on ME10 and ME20 systems. Camshaft timing is adjustable and this discrete parameter
indicates the state of the camshaft timing solenoid. When the display reads ON, the solenoid is
energized and when the display reads OFF it is not. Engine speed influences when the display
reads ON or OFF. OFF indicates full retard position, and ON, full advance. The solenoid should
be OFF at speeds below 2000 RPM, ON at speeds between 2000 RPM and 4300 RPM, and
OFF at speeds over 4300 RPM.
ADR ACTIVE
Range: __________________________________________________________ ON/OFF
Used on ERE/EVE/ASF (IFI Diesel)) systems. This parameter indicates whether the ADR system
is active or not. No further information is available.
ADR RPM ADJUSTMENT
Range: __________________________________________________________ ON/OFF
Used on ERE/EVE/ASF (IFI Diesel)) systems. This parameter indicates whether the ADR RPM
adjustment is on or off. No further information is available.
AFTER-START ENRICHMENT
Range: __________________________________________________________ ON/OFF
Used on HFM. LH, ME10, ME20, ME27, ME28 and SIM4 systems. This parameter indicates if
the ECU is providing a rich fuel mixture after a cold start. The display reads ON with fuel
enrichment at cold start, then switches to OFF once the engine warms up.
AIR CONDITIONING
Range: __________________________________________________________ ON/OFF
Used on ME27, ME28 and SIM4 systems. This parameter indicates whether the ECU is
commanding the air conditioning system is on or off.
AIR FLAP
Range: _________________________________________________________ 0 to 100%
Used on ME20 systems. This parameter indicates the opening of the air flap as a percentage. At
0% the air flap is fully open, and at 100% is completely closed. The air flap controls supercharger
boost based on air flap position, which is ECU pulse-width modulated. At 100% the air flap is
closed; at 11 to 99% boost control is in part load range; and at 10% or less the air flap is open.
AIR FLAP SWITCHOVER ANGLE
Range: __________________________________________________________0 to 120°
Used on HFM systems. This parameter indicates the opening of the air flap in degrees. The ECU
uses this signal to regulate supercharger boost. When the supercharger is providing boost, the
reading should be greater than 85°.
