Data Parameters Engine Parameters
DESIRED ENGINE SPEED
Range: _____________________________________________________ 0 to 1500 RPM
Used on HFM systems. This parameter indicates the target idle speed that the ECU is attempting
to maintain. With a normal running engine, actual and desired engine speeds should be equal or
close to each other.
DISTRIBUTOR SHAFT ACTUAL POS.
DISTRIBUTOR SHAFT NOMINAL POS.
Range: _________________________________________________________ 0 to 100%
No information is available at this time.
DRIVE AUTH. RCL & ECM COMPATIBLE
Range: __________________________________________________________ YES/NO
Used on HFM systems. This parameter indicates whether the remote controller locking (RCL)
system and the ECU correctly identified each other. The display reads YES if the modules are
properly coded. Coding cannot be erased, so swapping modules for testing cannot be done
unless a matched pair is used.
DRIVE AUTHORIZ.,IMMOBOLIZER
Range: _______________________________________________ ACTIVE/NOT ACTIVE
Used on ME27 and ME28 systems. This parameter indicates whether the driver immobilizer is
active or not active. The driver immobilizer is that part of the antitheft system that allows the
vehicle to be remotely disabled via satellite. Often this parameter may read ACTIVE with a faulty
or wrong ignition key.
DRIVER GIVEN TORQUE
Range: ______________________________________________________ not available
Used on HFM systems. No information is available at this time.
DWELL TIME, CYLINDER 1 to 12
Range: ______________________________________________________ not available
Used on ME27 and ME28 systems. This parameter displays the dwell timing (coil saturation
time) for the various cylinder banks in seconds.
EBR INTERVENTION
Range: __________________________________________________________ ON/OFF
Used on ME10 systems. This parameter indicates the state of the engine brake regulation
(EBR), or traction control, system. Display reads ON when EBR has been activated and OFF
during normal driving.
ECM IDENTIFIED
ENGINE CONTROL MODULE IDENTIFIED
Range: __________________________________________________________ YES/NO
Used on ERE/EVE/ASF (IFI Diesel)), ME10, ME20 and HFM systems. These parameters
indicate whether the drive authorization system (DAS) and ECU have correctly identified each
other. The display reads YES if the modules have correctly identified each other and will read NO
if they have not correctly identified each other. The modules are coded together and the mutually
shared code cannot be erased.
ECM LOCKED
ENGINE CONTROL MODULE LOCKED
Range: __________________________________________________________ YES/NO
Used on ERE/EVE/ASF (IFI Diesel)), ME10, ME20 and HFM systems. These parameters show if
the drive authorization system (DAS) and ECU have correctly identified each other. If the display
reads YES, the modules have not identified each other and the engine is prevented from starting.
