Hi Mike.I need to checkout the line pressure control solenoid within the automatic transmission case for continuity/short circuit and the associated connectivity back to the Transmission Control Module. I therefore need to know where to stick my meter probes/circuit tester. I need to know which plug/plug pins/wire colours and which TCM pin sockets make up the relevant circuit. In essence,a wireing diagram or description. Simple in concept but complicated in design. Nothing in Haynes.Can't find anything for T5 on web! Bit of a challenge I guess.

Hi Derek-
Ok yes I understand what you are up against. Just a point, depending on what machine you are using for diags..can you not get what you need in Live Data mode? I will have a look though and see what I can find for you -as you say, Volvo are not too clever with this info.

Ok but I would stress at this stage all I need to proceed is the physical location of the circuitry and colour codeing.Once identified I hope to pinpoint the problem and hope it's not actually in the box.A wiring diagram is the key or the information gleened from it..

Just a thought Derek - where are you / what country?
Customer: replied 2 years ago.

Wales,sa340xt. How about you?

Expert:  Mike replied 2 years ago.
Ah right - Im in the UK.. I just wondered as US cars for example can be different -
Ok Derek - leave it with me a bit - No need to reply - I'll get back to you -

OK,have replied as webpage says "we're waiting for you"(me). A little dissapointed so far as I thought the info' required would be at your finger tips by way of familiar(to a Volvo technician)official Volvo literature.Hope I can proceed by tomorrow.

Edited.

I did say Derek that the info was not that readily available even from Volvo which is where it comes from in the first place... I then said I would do my best to see what I could find for you- that's what I have been doing but I'm not here 24/7 I'm afraid and am very busy.
Evidently Im not looking into this fast enough for you Derek so Im going to Opt Out of this question - This will release the question onto the live list again for you.
You must not reply to this or the question will be locked - You need to wait for another expert from here -
I'm sorry I could not help you personally.
Rgds, MIKE
