Data Parameters Engine Parameters

VEHICLE SPEED FRONT AXLE

VEHICLE SPEED REAR AXLE

Range: ___________________________________________________ 0 to vehicle max

Used on ME 10, ME 20 and SIM4 systems. These parameters indicate the speed of the front and

rear axles based on input signals to the ECU from the wheel speed sensors. The measurement

can be changed from kilometers per hour (KPH) to miles per hour (MPH).

VEHICLE SPEED

VEHICLE SPEED SIGNAL (VSS)

VSS

Range: ___________________________________________________ 0 to vehicle max

Used on DM, DM2, HFM, LH, and ME10 systems. This parameter indicates the vehicle speed

based on the vehicle speed sensor (VSS) input signal to the ECU. Measurement units can be

changed from kilometers per hour (KPH) to miles per hour (MPH).

VMIN NOT MAINTAINED

Range: __________________________________________________________ YES/NO

Used on HFM systems. This parameter indicates if the charging system is maintaining the

minimum required voltage. The display reads NO during normal operation and reads YES when

charging system output falls below the minimum voltage requirement.

WARM-UP

Range: __________________________________________________________ ON/OFF

Used on HFM and LH systems. This parameter indicates whether or not the ECU is operating the

engine in warm-up mode following a cold start. The display reads OFF during normal driving with

a warm engine, and ON from a cold start with engine in warm-up mode.

WOT (FULL LOAD) CONTACT

WOT (FULL LOAD) INFO. LOAD

WOT (FULL LOAD) RECOGNITION

WOT (FULL LOAD)

Range: __________________________________________________________ ON/OFF

Used on DM2, HFM, LH, ME10, and ME20 systems. This parameter indicates the state of the

wide-open throttle (WOT) switch. The display reads OFF during normal driving and reads ON

with throttle at wide open under full load acceleration.

WOT (FULL LOAD) INFO.THR.VLV.POS

Range: __________________________________________________________ ON/OFF

Used on DM2 systems This parameter shows the state of the wide-open throttle (WOT) switch.

The Scanner displays OFF during normal driving, and ON during operation at wide open throttle

under full load acceleration. The ECU relies on the electronic accelerator actuator input signal to

determine whether the engine is at full load acceleration.
