Data Parameters Engine Parameters
CRUISE CONTROL LEVER POSITION VARIABLE
CRUISE CONTROL LEVER SIGNAL IMPLAUSIBLE
CRUISE CONTROL OFF
CRUISE CONTROL RESTART
CRUISE CONTROL SET AND ACCELERATE
CRUISE CONTROL SET AND DECELERATE
Range: __________________________________________________ACTIVE/INACTIVE
Used on SIM4 systems. These parameters represent the status of the cruise control system. The
display reads ACTIVE when cruise control is running and INACTIVE when not running.
CRUISE CONTROL SHUT-OFF FUNCTION
Range: __________________________________________________________ ON/OFF
Used on ME10 and ME20 systems. This parameter represents the cruise control system status.
Note the parameter is a shut-off function, so the display reads OFF when cruise control is
engaged and ON when disengaged.
CRUISE CONTROL SHUT-OFF SAFETY
Range: __________________________________________________________ YES/NO
Used on ME10 and ME20 systems. This parameter represents the status of the cruise control
safety switch in the electronic accelerator actuator. The ECU connects to the safety switch in the
electronic accelerator actuator. Normal operation sends a positive signal to ECU. If throttle
opening is more than the position specified and cruise control is not engaged, the switch sends a
ground signal to the ECU, which turns off fuel injection. Injection switches on once engine speed
is below 1200 RPM.
CRUISE CONTROL/SPEED LIMITER INTERVENT
Range: __________________________________________________________ ON/OFF
Used on ME10 systems. This parameter indicates if the ECU is disabling the cruise control
system due to excessive engine speed. The display reads ON if the maximum engine speed
limitation is reached and cruise control operation is suspended. The display should read OFF
during normal cruise control operation.
CRUISE CONTROL SWITCH
Range: __________________________________________________________ ON/OFF
CRUISE CONTROL SWITCH A
CRUISE CONTROL SWITCH B
CRUISE CONTROL SWITCH ACCELERATE
CRUISE CONTROL SWITCH DECELERATE
Range: __________________________________________________________ YES/NO
Used on ERE/EVE/ASF (IFI Diesel)) and HFM systems. This parameter indicates the status of
the cruise control switch. ON or YES means that the switch is in the ON position.

Range: _________________________________________________ –0.700 to 0.700 ms
Used on ME27 systems. These parameters indicate the fine tuning long term fuel trim correction
to the fuel injection pulse width in milliseconds (ms). Cylinder shutoff (CSO) mode is used on the
V12 engines with separate bank fuel control. Information on CSO mode is limited, however field
technicians believe that if correct cruise conditions are met, cylinder groups are shut down to
conserve fuel. (See the description for CYLINDER SHUT-OFF 1.) In this mode, mixture
adaptation is modified for the active cylinders, compensating for variations in air mass and
pressure ratios. This number is learned by the ECU and used to correct small differences
