PRESS CONT SOL (PRESSURE CONTROL
SOLENOID, %)
Electric current value ratio between electric current value
being outputted from TCM to solenoid and maximum
value can be outputted by TCM.
VEHICLE SPEED (KPH/MPH)
Vehicle speed computed by reference pulses coming
from vehicle speed sensor on transaxle case.
O/D OFF SWITCH (ON/OFF)
Inputted signal from O/D off switch on selector knob.
ON: O/D off switch ON
OFF: O/D off switch OFF
TRANS. RANGE (P/R/N/D/2/L)
Transaxle range detected by signal fed from
transmission range sensor.
D RANGE SIGNAL (P/N RANGE/D RANGE)
Transaxle range detected by signal fed from
transmission range sensor.
THROTTLE POSITION (THROTTLE POSITION, %)
Throttle opening ratio computed by duty signal from
ECM.
A/T Basic Check
This check is important for troubleshooting when TCM has detected no DTC and no abnormality has been noted in
visual inspection. Follow the flow table carefully.
