Does anyone happen to have a couple screenshots of the A/C signal circuit testing procedure?

1996 4runner 3.4 4x4

1996 ac ewd

Thank you.

I should have been more specific.

Using a 2000 4runner FSM while trying to diagnose DTC P0505, it says if you pass the idle test, to move on to step 6: Check A/C signal circuit (See page AC−91).

you can jump the 2 pin AC pressure sensor connector under the hood on the AC line, if everything is working the AC clutch should engage, that should tell you if its a pressure issue and if the AC clutch is working correctly.

Using the wrong year fsm could be bad idea in certain instances.


As there are 3 different climate controls in this generation.

1996 is quite a bit different wiring then a 2000.

I understand that. Reason for the 2000 FSM is because it's what was available and is essentially what Timmy the Toyota Guy says in his video.

The reason is nobody wants to pay for them. Let's be honest. Nobody wants to pay for the paper versions or the techstream subscriptions.

Thus why folks are always looking for a an electronical wiring diagrams etc.

I actually got the tech scream subscription to down all the electronical diagrams for all the 3rd gen models.

So I can work on my fleet of 3rd gens. I release the EWD only to help people.

But I am done helping on this thread. Good luck.
