Automatic Transmission/Transaxle: 5A-21
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.
BRAKE SWITCH (ON/OFF)
Inputted signal from brake light switch on pedal bracket.
ON: Brake pedal depressed
OFF: Brake pedal released
TORQ REDUCTION SIG (TORQUE REDUCTION
SIGNAL, ON/OFF)
ON: Signal which TCM require ECM to reduce output
torque at shifting gear
OFF: Signal which TCM does not require ECM to reduce
output torque
COOLANT TEMP. (
°
C,
°
F)
Engine coolant temperature computed by duty signal
from ECM.
A/C SWITCH
ON: Signal which inform that air conditioner compressor
is turned ON.
OFF: Signal which inform that air conditioner
compressor is not turned ON.
ENGINE TORQUE (N
⋅
m)
Engine torque computed by duty pulse signal outputted
from ECM.
A/T Basic Check
S3RH0B5104010
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.
