Data Parameters Engine Parameters
STARTER CONTROL
Range: __________________________________________________________ YES/NO
STARTER LOCK-OUT OUTPUT
STARTER LOCK-OUT REED CONTACT
STARTER LOCK-OUT STATUS
Range: __________________________________________________________ ON/OFF
Used on HFM and EGS systems. These parameters indicate whether the immobilizer system is
locking out the starter system. The display reads YES/ON if the starter system is disabled.
STARTER SIGNAL CIRCUIT 50
Range: __________________________________________________________ ON/OFF
Used on HFM systems. This parameter indicates the state of circuit 50, which is the starter
circuit. The display reads ON when the starter is cranking, then switches to OFF after the engine
starts.
STOP LAMP SWITCH
Range: __________________________________________________________ ON/OFF
Used on ME10, ME20, ME27, ME28 and SIM4 systems. This parameter indicates the state of
the brake light switch. The display reads ON if the brake light switch circuit is closed, brake lights
on, and OFF when the circuit is open.
STOP LAMP SWITCH N.C. CONTACT
STOP LAMP SWITCH N.O. CONTACT
Range: __________________________________________________________ ON/OFF
Used on ERE_EVE_ASF (IFI Diesel)). No information is available.
SUPERCHARGER CLUTCH
Range: __________________________________________________________ ON/OFF
Used on ME20 systems. This parameter indicates the state of the supercharger clutch. The
display reads ON if the supercharger clutch is engaged to increase boost, and OFF when the
clutch is disengaged.
SUPERCHARGER EFFICIENCY FACTOR
Range: __________________________________________________________ variable
Used on ME20 systems. This parameter indicates the ECU-calculated supercharger efficiency
factor, which reflects supercharger performance. Readings vary with speed and load. Typically, if
driving in third gear at 3500 RPM under full load, the reading should be greater than 1.3.
TANK FILL LEVEL
Range: _______________________________________________________ OK/NOT OK
Used on ME20 systems. This parameter indicates whether there is the proper amount of fuel in
the fuel tank to run an evaporative emissions (EVAP) test. The display reads OK if the fuel level
is within test range and NOT OK if the fuel level outside the test range.
TANK PRESSURE DIFFERENCE
Range: __________________________________________________________ variable
Used on ME10 and ME20 systems. This parameter, which displays in millibar (mbar), indicates
the results of an ECU-performed fuel tank leak test. This test is part of the OBD-II monitoring
system. The fuel tank pressure test uses an internal fuel tank pressure sensor.
To perform this leak test, the ECU closes the canister shut-off valve to the activated charcoal
canister and opens the purge control valve. This allows intake manifold vacuum into the fuel
tank, where it is detected by the fuel tank pressure sensor. Tank pressure difference must read
about -7 mbar within about 10 seconds or a major leak exists. If no major leak is detected, the
