Reverse clutch
Low & reverse brakeFront planetary carrier is stationary because of the operation of low and reverse brake.
Input power is transmitted to front sun gear through reverse clutch, which drives front
internal gear in the opposite direction.
Engine brakeAs there is no one-way clutch in the power transaxle line, engine brake can be obtained
when decelerating.

TCM FunctionINFOID:0000000001714311
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.

*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:0000000001714314
 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.

SHIFT SOLENOID VALVE A
DescriptionINFOID:0000000001713002
Shift solenoid valves A and B are turned ON or OFF by the TCM in response to signals sent from the PNP
switch, vehicle speed and ECM (throttle opening). Gears will then be shifted to the optimum position.

On Board Diagnosis LogicINFOID:0000000001713004
Diagnostic trouble code “SHIFT SOLENOID/V A” with CONSULT-III or 4th judgement flicker without CON-
SULT-III is detected when TCM detects an improper voltage drop when it tries to operate the solenoid valve.

DTC Confirmation ProcedureINFOID:0000000001713006
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 and select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
2. Touch “START”.
3. Start engine.
4. Drive vehicle in “D” position and allow the transaxle to shift 1 → 2 (“GEAR”).
5. If the check result is NG, go to TM-361, "
Diagnosis Procedure".
WITHOUT CONSULT-III
1. Start engine.
2. Drive vehicle in D
1→ D2 position.
3. Perform self-diagnosis. Refer to TM-38, "
Diagnosis Procedure without CONSULT-III".
4. If the check result is NG, go to TM-361, "
