Terminal 30


Recommended Posts

Can anyone tell me and/or provide a picture of where this elusive Terminal 30 is located in a 2000 986 2.7L? Apparently, this terminal is causing me a metric **** ton of challenges. I can find mention of where it is located. Please help!!!

Brown - ground - Terminal 31

Yellow/Black - telephone mute

Green/Black - switched 12 volts  - Terminal 15

Red/Green - unswitched 12 volts - Terminal 30

 

This connector is right behind the HVAC control in the center console on all USA/Canada cars (telephone prep).

Welcome to RennTech :welcomeani:
Let’s start with the obvious: What exactly are you attempting to do?

I have a series of faults identified there by the scanner. I am also experiencing starting issues door lock issues. All seems like terminal 30 from what I have read. Apparently, there are a lot of systems that run through it.

OK, here’s the problem: There are more than one “terminal 30” in these cars.  Lorne has pointed out the one on the cell phone cable under the center part of the dash, and there is another one on the fuel pump relay.

 

So let’s go back and start with your faults, exactly which fault codes are you getting?

The faults are 05 (alarm) and the other is airbag. However, since I am having fuel delivery issues on start, I wanted to check that terminal.

I think your problem may rest with the central locking computer under the driver’s seat, which prevents the car from starting by shutting off the fuel and ignition.  These cars are infamous for letting water accumulate in the area where the control unit is located, causing corrosion and shorts that lead to problems with the windows, starting, locking the car, and an entire host of other nightmares. Suggest disconnecting your battery, removing your driver seat, pulling the control unit and opening it up; if it shows any signs of corrosion or water, that needs to be fixed first.  There have been an endless list of posts here and elsewhere about this issue with photos of what a damaged control unit looks like.  Good luck, and this is not an inexpensive repair.
