REFERENCE VALUES

NOTICE:

1. The CONSULT-III electrically displays shift timing and lock-up timing (that is, operation timing of each

solenoid).

Check for time difference between actual shift timing and the CONSULT-III display. If the difference is

noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical

parts using applicable diagnostic procedures.

2. Shift schedule (which implies gear position) displayed on CONSULT-III and that indicated in Service Man-

ual may differ slightly. This occurs because of the following reasons:

-

Actual shift schedule has more or less tolerance or allowance,

-

Shift schedule indicated in Service Manual refers to the point where shifts start, and

-

Gear position displayed on CONSULT-III indicates the point where shifts are completed.

3. Display of solenoid valves on CONSULT-III changes at the start of shifting, while gear position is displayed

upon completion of shifting (which is computed by TCM).

Fail-Safe

INFOID:0000000006159426

The TCM has an electrical fail-safe mode. This mode makes it possible to operate even if there is an error in a

main electronic control input/output signal circuit. 

The TCM has an electrical fail-safe mode. This mode makes it possible to operate even if there is an error in a

main electronic control input/output signal circuit. In fail-safe mode the transmission is fixed in 2nd, 4th or 5th

(depending on the breakdown position), so the customer should feel “slipping” or “poor acceleration”. 

Even when the electronic circuits are normal, under special conditions (for example, when slamming on the

brake with the wheels spinning drastically and stopping the tire rotation), the transmission can go into fail-safe

mode. If this happens, switch “OFF” the ignition switch for 10 seconds, then switch it “ON” again to return to

the normal shift pattern. Therefore, the customer's vehicle has returned to normal, so handle according to the

“diagnostics flow” (Refer to 

TM-6, "Work Flow"

).

FAIL-SAFE FUNCTION 

If any malfunction occurs in a sensor or solenoid, this function controls the A/T to mark driving possible.

Output Speed Sensor

• Signals are input from two systems - from output speed sensor installed on the transmission and from com-

bination meter so normal driving is possible even if there is a malfunction in one of the systems. And if output

speed sensor has unusual cases, 5GR is prohibited.

Accelerator Pedal Position Sensor

• If there is a malfunction in one of the systems, the accelerator opening angle is controlled by ECM according

to a pre-determined accelerator angle to make driving possible. And if there are malfunctions in tow sys-

tems, the engine speed is fixed by ECM to a pre-determined engine speed to make driving possible.

Throttle Position Sensor

• If there is a malfunction in one of the systems, the accelerator opening angle is controlled by ECM according

to a pre-determined accelerator angle to make driving possible. And if there are malfunctions in tow sys-

tems, the accelerator opening angle is controlled by the idle signal sent from the ECM which is based on

input indicating either idle condition or off-idle condition (pre-determined accelerator opening) in order to

make driving possible.

Transmission Range Switch

• In the unlikely event that a malfunction signal enters the TCM, the position indicator is switched “OFF”, the

starter relay is switched “OFF” (starter starting is disabled), the back-up lamp relay switched “OFF” (back-up

lamp is OFF) and the position is fixed to the “D” range to make driving possible.

Starter Relay

• The starter relay is switched “OFF”. (Starter starting is disabled.)

Interlock

• If there is an interlock judgment malfunction, the transmission is fixed in 2GR to make driving possible.

NOTE:

When the vehicle is driven fixed in 2GR, a input speed sensor malfunction is displayed, but this is

not a input speed sensor malfunction.

• When the interlock is detected at the 3GR or more, it is locked at the 2GR.

1st Engine Braking

• When there is an 1st engine brake judgment malfunction, the low coast brake solenoid is switched “OFF” to

avoid the engine brake operation.

Line Pressure Solenoid

• The solenoid is switched “OFF” and the line pressure is set to the maximum hydraulic pressure to make driv-

ing possible.

Torque Converter Clutch Solenoid

• The solenoid is switched “OFF” to release the lock-up.

Low Coast Brake Solenoid

• When a (electrical or functional) malfunction occurs, in order to make driving possible, the engine brake is

not applied in 1GR and 2GR.

 Input Clutch Solenoid

• If a (electrical or functional) malfunction occurs with the solenoid either “ON” or “OFF”, the transmission is

held in 4GR to make driving possible.

Direct Clutch Solenoid

• If a (electrical or functional) malfunction occurs with the solenoid either “ON” or “OFF”, the transmission is

held in 4GR to make driving possible.

Front Brake Solenoid

• If a (electrical or functional) malfunction occurs with the solenoid “ON”, in order to make driving possible, the

A/T is held in 5GR; if the solenoid is OFF, 4GR.

High and Low Reverse Clutch Solenoid

• If a (electrical or functional) malfunction occurs with the solenoid either “ON” or “OFF”, the transmission is

held in 4GR to make driving possible.

Input Speed Sensor 1 or 2

• The control is the same as if there were no input speed sensors, 5GR is prohibited.
