Forward clutch (Does not affect power
transmission)Input power is transmitted to front carrier through high clutch.
This front carrier turns around the sun gear which is fixed by brake band and makes
front internal gear (output) turn faster.
Engine brakeAt D

can be obtained when decelerating.

TCM FunctionINFOID:0000000001694422
The function of the TCM is to:
 Receive input signals sent from various switches and sensors.
 Determine required line pressure, shifting point, lock-up operation, and engine brake operation.
 Send required output signals to the respective solenoids.
CONTROL SYSTEM OUTLINE
The automatic transaxle senses vehicle operating conditions through various sensors or signals. It always
controls the optimum shift position and reduces shifting and lock-up shocks.

P*1: Spare for vehicle speed sensor·A/T (revolution sensor)
*2: Spare for accelerator pedal position signal
*3: If these input and output signals are different, the TCM triggers the fail-safe function.
*4: Used as a condition for starting self-diagnostics; if self-diagnosis are not started, it is judged that there is some kind of error.
*5: Input by CAN communications.
*6: Output by CAN communications.
Line Pressure ControlINFOID:0000000001694425
 TCM has various line pressure control characteristics to match the driving conditions.
 An ON-OFF duty signal is sent to the line pressure solenoid valve based on TCM characteristics.
 Hydraulic pressure on the clutch and brake is electronically controlled through the line pressure solenoid
valve to accommodate engine torque. This results in smooth shift operation.
NORMAL CONTROL
The characteristic of the line pressure to the throttle opening is set
for suitable clutch operation.
BACK-UP CONTROL (ENGINE BRAKE)
If the selector lever is shifted to “2” position while driving in D4 or D3,
great driving force is applied to the clutch inside the transaxle. Clutch
operating pressure (line pressure) must be increased to deal with
this driving force.

DTC P0705 PARK/NEUTRAL POSITION (PNP) SWITCH
DTC P0705 PARK/NEUTRAL POSITION (PNP) SWITCH
DescriptionINFOID:0000000001694283
 The PNP switch assembly includes a transaxle range switch.
 The transaxle range switch detects the selector lever position and sends a signal to the TCM.
CONSULT-III Reference Value in Data Monitor ModeINFOID:0000000001694284
Remarks: Specification data are reference values.
On Board Diagnosis LogicINFOID:0000000001694285
 This is an OBD self-diagnostic item.
 Diagnostic trouble code “P0705 PNP SW/CIRC” with CONSULT-III is detected when TCM does not receive
the correct voltage signal from the switch based on the gear position.
Possible CauseINFOID:0000000001694286
 Harness or connectors
[The PNP switch circuit is open or shorted.]
 PNP switch
DTC Confirmation ProcedureINFOID:0000000001694287
CAUTION:
 Always drive vehicle at a safe speed.
 If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at
least 10 seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “A/T” with CONSULT-III.
3. Touch “START”.
4. Start engine and maintain the following conditions for at least 5 consecutive seconds.
VEHICLE SPEED: 10 km/h (6 MPH) or more
THROTTLE POSI: More than 1.0/8
SLCT LVR POSI: “D” position
5. If the check result is NG, go to TM-44, "
Diagnosis Procedure".
WITH GST
Follow the procedure “WITH CONSULT-III”.
