5A-60 AUTOMATIC TRANSMISSIONDIAGNOSIS
DIAGNOSTIC SYSTEM Recommended T est Equipment and Procedure
The test equipment is designed to be used with the control modules in all vehicles. The components used in the transmission application are: Multi Function Tester, and
Appropriate vehicle for testing.
Multi Function Tester (MFT)
The MFT is programmed with the special vehicle diagnostic software that allows selection of the unit under test.
The program allows the proper communication to the Transmission Control Unit (TCU).
It then requests information from the user via a menu system to select the required set up.
Examples are viewing codes, clearing error codes, and real-time operation. Set up and operation instructions are detailed in the user manual.
This equipment can be used by trained personnel such as technicians and mechanics to diagnose electronic and
wiring problems relating to the vehicle transmission. Information that is available includes engine and road (shaft)
speed, transmission oil temperature, throttle position, solenoid/gear status and gear lever position. Current andstored faults detected by the electronics are also available.

OP Description
This switch has discreet values indicating the
positions selected by the gear shift lever
(PRNDL). Voltage varies 0V to 5V.
Resistive sensor indicates transmission tem-perature .High R = low temp Low R = high temp
Voltage varies 0V to 5V.
On/Off solenoid normally open, combines with
other On/off solenoid 3 for shift quality and se-quencing.
On/off solenoid normally open, combines with
other On/off solenoid to set the selected gear.
This ensures the earth path for the VPS and
the current in this line is monitored to give feed-
back control of the VPS. PRNDL switch ground. Ground reference for temperature sensor in-
put.
On/Off solenoid normally open, sets low/high line pressure.
On/off solenoid normally open, combines with
other On/off solenoid to set the selected gear.
On/off solenoid normally open, combines with
On/off solenoid 4 for shift quality and sequenc- ing.
On/off solenoid normally open, locks up the
torque converter to Increase cruising efficiency. This is the variable force solenoid which ramps the pressure during gear changes and solenoid
switching, to enhance transmission shift quality.

2. Ignition “OFF ”.
3. Connect SCANNER with diagnosis connector in engine room.
4. Ignition “ON ”.
5. Read the current memorized specification in TOD control unit.
6. Compare memorized specification with the checked record. If not matched, perform a coding.
7. Read again memorized coding specification in TOD control unit for confirmation of coding.
8. Check coding specification whether it matches with vehicle or not. If not, perform a coding again.

1. This valve is used in no-load sharp acceleration mode.
2. Solenoid valve (Normal Open type)


 Normal: Solenoid valve opens, then intake
manifold pressure will operate ALDA.


 No-load sharp acceleration mode: Solenoid valve
closes, then vacuum pressure operate ALDA.
3. Operating voltage: approx. 12 V
4. Resistance: approx. 22.4 ± 1.4
5. Check the connections in each passage when supplying or cutting off the operating voltage.
The valve passage to ALDA will be changed when the battery voltage is supplied through EGR control unit.
Changed to ALDA (1 to 3) or vacuum from intake manifold
Changed to ALDA (2 to 3) from modulator 2 (Refer to exhaust gas control mode with no-load sharp acceleration)
