Engine Parameters

A/C COMPRESSOR

Range: __________________________________________________________ ON/OFF

Used on DM2, HFM, ME10 and ME20 systems. This parameter shows the condition of the A/C

compressor. The display reads ON with air conditioning compressor activated (engaged).

ABS. INT. MANIF. PRESS. DI1

ABS. INT. MANIF. PRESS. DI2

ABS. INTAKE MANIFOLD PRESSURE

Range: ______________________________________________ 0 to 1000 or ±100 mbar

Used on DM systems. These parameters, which display intake manifold absolute pressure in

millibars, are used by the ECU for making camshaft timing adjustments and for detecting EGR

flow on vehicles equipped with EGR systems. The “ABS.” in the parameter name is an

abbreviation for absolute, not anti-lock brake.

ACCEL. PEDAL POSITION SENSOR

Range: _________________________________________________________ 0 to 100%

Used on ERE/EVE/ASF (IFI Diesel) systems. This parameter indicates the position of the

accelerator pedal (sensor) as a percentage. Normally, readings range from 0 to 2% at idle, and

75 to 95% at wide open throttle.

ACCELERATION ENRICHMENT

Range: __________________________________________________________ ON/OFF

Used on LH systems. This parameter indicates if the ECU is adjusting the fuel mixture to

compensate for heavy acceleration. The display should read OFF with the engine running at idle,

and should read ON when the throttle is snapped to about 4000 RPM.

ACCELERATION SENSOR

Range: _________________________________________________________ 0 to 5.0 V

Used on ME10 systems. This parameter indicates the position of the accelerator pedal (sensor)

as voltage.

ACTUAL EGR LIFTING SENDER

Range: ______________________________________________________ not available

Used on ERE/EVE/ASF (IFI Diesel)) systems. This parameter displays the EGR lifting sender

position (equivalent to an EGR pintel position sensor) in millimeters (mm). The greater the value,

the wider open the EGR valve.

ACTUAL INJECT.QTY. PER STROKE

Range: __________________________________________________________ variable

Used on ERE/EVE/ASF (IFI Diesel)) systems. This parameter displays the actual fuel quantity

injected per stroke. Normal warm engine idle readings vary from 30 to 33. A fuel quantity

actuator mounted to the main injection pump housing moves a control rod to regulate the

quantity of injected fuel.

ACTUAL INTAKE AIR PRESSURE

Range: _____________________________________________________0 to 1000 mbar

Used on EDS systems. This parameter displays the actual air intake pressure in millibars. The

Scanner relies on a pressure sensor that measures intake manifold pressure for this value.
