Data Parameters Transmission Parameters
TRANSMISSION OVERLOAD PROTECTION
TRANSMISSION OVERLOAD PROTECTION INTER
TRANSMISSION OVERLOAD PROTECTION FEEDBACK
Range: __________________________________________________________ ON/OFF
Used on EZ, HFM, ME10 and ME20 and EAG systems. These parameters show whether or not
the ECU is operating the automatic transmission in an overload protection mode. The display
normally reads OFF, and reads ON if transmission overload protection mode is active. In
overload mode the ECU disables the torque converter clutch and overdrive.
TRANSMISSION SENSOR B49(1/MIN)
Range: ______________________________________________________ not available
This parameter displays the CAN signal from the traction system. The value should increase and
decrease in proportion to the rotational speed of the wheel.
The CAN is a broadcast type of bus. This means that all modules “hear” all transmissions. There
is no way to send a message to just a specific module; all modules invariably pick up all traffic.
However, CAN hardware provides local filtering so each module reacts only to data whose
identifiers are stored in its acceptance list. This very high frequency transmission requires a
“twisted pair” of wires to address electromagnetic interference (EMI) concerns. Two wires also
ensure communication if one wire is damaged and provide the ability to recognize a CAN circuit
fault. The two lines must not be interchanged as each represents either a high or low level.
TRANSMISS. OIL TEMP.R/D/4/3/2/1(°C)
TRANSMISS. OIL TEMP.R/D/4/3/2/1(°F)
Range: ______________________________________________________ not available
Used on the EGS system. These parameters display the electronic transmission controller
(ETC)-calculated ATF temperature. The ETC relies on the transmission temperature sensor
voltage signal for this parameter value. Current temperature can only be read with selector lever
in positions R, D, 4, 3, 2, 1, with STARTER LOCK-OUT REED CONTACT displaying ON, and
LIMP-HOME displaying NO. Transmission oil temperature has an influence on the shift time and
shift quality. The transmission temperature sensor is connected in series with the starter lockout
reed contact switch.
TRANSMISSION RANGE D5
Range: __________________________________________________________ ON/OFF
Used on the EAG system. This parameter indicates if 5th gear is selected. Although 5th gear is
selected, the 4 to 5 up shift at full throttle will not occur until reaching the cutoff speed. Under
these conditions high-powered vehicles may never shift into 5th gear below 155 mph (250 km/h).
TURBINE SPEED (1/MIN)
Range: _____________________________________________________ 0 to 8000 RPM
Used on EGS systems. The electronic transmission controller (ETC) receives an A/C signal from
the front planetary sensor, which senses the speed of the front planetary gear. The ETC then
changes this analog signal into a digital signal, and compares it to an internal fixed clock signal to
determine actual turbine speed. The ETC performs this operation once per minute.
VALVE CURRENT 1 (MA)
VALVE CURRENT 2 (MA)
Range: ______________________________________________________ not available
Used on EAG systems. No information is available at this time.
VALVE PRESSURE (MBAR)
Range: ______________________________________________________ not available
Used on EAG systems. No information is available at this time.
