Using a scan tool

We used a scan tool on a 1997 mitsibitchi galant.The first thing we did was to go on to the ABS life data and record all the sensors:

Front right wheel speed sensor
front left wheel speed sensor
rear left wheel speed sensor
rear right wheel speed sensor
brake light switch

After doing this I went to the actuator test screen and listed the tested components.
solenoid valve 1
solenoid valve 2
solenoid valve 3

Next thing we did on this car was the electronic transmission
First we had to know what everything means.
PCM:powertrain control module
TCC:Torque converter clutch
TPS:Throttle position sensor
ECT:Engine coolant temperature
VSS:Vehicle speed sensor
PSA:transmission range fluid presure switch asembly
TTS:transmission temp sensor

I used the workshop manual to get all the sensors and actuators.

I also got the wiring diagram for the system.

Got the pictures above from:

I used the folowing diagram to answer some question that was asked.

Was aked which solenoid are on when the vehicle is shifted ibto drive and starts in first gear:
2nd and OD
which solenoids are on when the vehicle automaticaly shifts into second gear:
OD and LR
which solenoids are on when the vehicle automatically shifts into third gear:
LR and 2nd
which solenoids are on when this vehicle automatically shifts into fourthb gear:
LR and UD

I got all these results by looking on the chart showen above
If there is a shift solenoid malfunction and vehicle is stuck in a high gear it would want to stall and when stuck in a lower gear like first wont be able to go fast probably only about 60kmph in most cars.

I used the repair information to pick two codes.
code 58
transmission fluid temoerature
to repair this fault I can check for voltage drop at the signal wire and compare the signal voltage to the manufacturers spec.

code 82
1-2 shift solenoid circuit faulty.

to diagnose this fault I can check all the earths to make sure I have a good earth and see if I hav a high resistance.
