420A where to hook up multimeter for tcu codes

[Extremities]

I'm getting ready to pull the tcu codes tomorrow and I have no idea where they hook up at. I'm sadly a victim of limp mode

Any help is much appreciated.

I have a 98 spyde gs and I dont see anything where its supposed to be in that picture.

Aah your a 420a car then...
Should still be a F4A23 trans.
But a voltmeter with black voltmeter lead in either ground terminal 4 or 5 & the other voltmeter red lead in terminal 6 should get you codes when key is turned on.

I feel like a retard for asking but I am so beyond new to cars its annoying. I'm 17 and learning how everything works but where exactly would I be plugging in at? Again, sorry for the stupidity.

A volt meter. In the diagnostic connector under the drivers side of the dash.
It looks just like the connector in the 1st picture I posted above.
Just make sure you get the correct terminals.

Just need to read the voltage pulses from the computer to get the code.
It will pulse the first number hold the voltage longer than the short pulses of the second number.
Hard to explain but it will become self evident when you do it for yourself.

Here look @ this picture, the voltmeter will pulse like this pattern for code.
The bottom of the line will be 0 volts the top of the line where the arrows point to will be the near 12 volt spike signals to indicate the code.

I know how to read the meter. I read the write up on plymouthlaser.com I meant where do I plug into the car?

I read over where you said where it plugs in at... oops is it the obd2 port?

 

[wrencher]

Yes OBD 2 port / diagnostic connector /data link connector....
