Data Parameters Transmission Parameters
A leaf spring that rests against the valve body presses the sensors against the transmission
housing. This insures a precise distance between the sensor tip and the front sun gear and
planet carrier.
To check, place the Start Engine Program Mode switch in position “W,” and move the gear
selector lever into position “P.” The difference between the nominal and current values should not
be greater than 50 RPM.
P/N RECOGNIZED
Range: __________________________________________________________ ON/OFF
Used on HFM systems. This parameter displays the status of the Park/Neutral position (PNP)
switch signal to the ECU. ON indicates that the selector lever is in the Park or Neutral position,
and OFF that the selector lever is in a position other than Park or Neutral.
PWM SOLENOID VALVE STATUS
Range: ________________________________________________CLOSED/SLIP/OPEN
Used on the EGS system. This parameter indicates the state of the electronic transmission
control module (ETC) output commands to the PWM (pulse width modulated) solenoid valve.
This valve engages the torque converter lockup clutch. The solenoid converts a PWM signal into
a corresponding regulated pressure (see SHIFT VALVE DUTY CYCLE for more information).
CLOSED means that the ETC is sending a duty cycle greater than 80% to the PWM solenoid,
thus engaging the torque converter lockup clutch.
SLIP means that the ETC is sending a duty cycle between 10 and 80 percent to the PWM
solenoid, setting the torque converter lockup clutch to its regulating position.
OPEN means that the ETC is sending a duty cycle of 0 percent to the PWM solenoid, shutting off
the torque converter lockup clutch.
RECOGNIZED TRANSMISSION GEAR
Range: ___________________________________________________________ 0, F, 3F
Used on the EGS system. This parameter displays the status of the transmission limp-home
mode. “0” indicates that the limp-home mode is not engaged; “F,” that the electronic transmission
controller (ETC) has detected a DTC, and placed the transmission in 2nd gear; “3F,” that the
ETC has engaged limp-home, and placed the transmission in 3rd gear.
R/P LOCK-OUT OUTPUT
Range: __________________________________________________________ ON/OFF
Used on the EGS system. The R/P lock solenoid is activated by the electronic transmission
controller (ETC), and moves the lever in direction of the cam, locking the shift shaft. The
supporting lever holds the lever in a position if the solenoid is not energized and can
automatically engage under severe vibrations. ON means that current is applied to lockout
solenoid, which prevents the transmission from being shifted into Reverse or Park above
approximately 6 mph. OFF means that no current is being applied to R/P lock solenoid which
allows the transmission to be shifted into Reverse or Park.
RR VSS(1/MIN) (RPM)
Range: ___________________________________________________ 0 to vehicle max
Used on the EGS system. This parameter displays the CAN signal from the traction system of
the right rear wheel speed senor. Display should increase and decrease in proportion to the
rotational speed of the wheel. The electronic transmission controller (ETC) updates this value
once per minute.
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
