Bench Test Driver Information Center (DIC)

**jejensen** · 05-13-2010

Does anyone know how to connect a digital Driver Information Center (DIC) from a 99 GT to a 12VDC power source to check if the lights and LCD are functional? It has a 24 pin connector on the back plus I have the mating plug with flying leads.

why two threads?

**jejensen** · 05-13-2010

Just trying to determine if the DIC I have is ok. The dash panel is a pain to remove so thought someone would know how to power it up without tearing apart another car just to test it. Thought another thread would be useful for someone trying to bench test their DIC.

i bet i can get that "hard to remove" panel out in 5min tops

less than that... are you kidding?

I dont think it'd work unless you had it hooked up to a PCM so it seems like a waste of time.

**jejensen** · 05-13-2010

Yeah, I can remove it pretty quickly too but didn't really want to tear into my buddy's GP to test the DIC if I didn't have to.

Yes, Connect the grey - pink - orange together on a 12+ volt dc supply or car battery. The two blacks are obviously ground, to the negative. I just did this and installed my DIC this past weekend!

Her is the plug view.

**jejensen** · 05-25-2010

Thanks Mikey for the schematics and letting me know which wires to connect for bench testing!

**Mikey** · 05-26-2010

Here's my old one on the bench so it can be done.

**jejensen** · 05-26-2010

Is that an LCD panel showing the outline of the car or is it similar to the other warning indicators on the right side?

**Mikey** · 05-26-2010

Yes it is the cars outline. The other are signal driven from the pcm & bcm. This is my old one. The other has a digital display. This one just has light bulbs in the back.

**jejensen** · 05-26-2010

Did you test your digital display before installing it using the wiring connections you mentioned earlier?

**Mikey** · 05-26-2010

Yes and the whole display lit up just like the pic you show earlier. That way I would know not to waste my time installing it if it was dead.

**jejensen** · 05-26-2010

That's exactly what I needed. Many THANKS!!

**Mikey** · 05-26-2010

No Prob Bro!

Thread resurection time.

I have two digital GTP DIC's here, and when I bench test them per Mikey's instructions, the only thing that lights up is the TCS light. I'm no slouch with wiring, but I'm sure I am doing something wrong.

Mikey, do you have your pictures hosted anywhere? Can you post a link to them?

Also, is the plug/harness from a regular GT DIC different from the digital GT or GTP harness? All that I can find mentioned is the number of wires (18 vs 24), and in this write-up ( 97-03 GP Digital Drivers Information Console Install ) buddy says, "I went ahead and just cut the old connector off and stripped the wires on both the body harness as well as the digital DIC pigtail", so I'm guessing that they are different?

Here you go kid...HOW - TO

The analog DIC has an 18 pin connector. The digital DIC has a 24 pin connector. You don't mention what year GP you have. My 2000 GT did not have both 18 and 24 pin connectors so I had to splice the 24 pin per the table in the post in the previous post There's also a write up in the "how to" section. If you have a 97 to 99 GP you should have both connectors already in the body harness, you'll just have to dig behind the dash to find it. If you have that then you should also have the connector should you decide to add the HUD.

Kid? Wow! Haven't been called that in over 30 years.

I've already read that thread a few times and it doesn't have the answers to my questions.

I have a 2002 GT. I don't plan on ever adding the HUD (they look butt-ugly IMO). So '00+ possibly don't have both connectors then. Thanks for the info.

Now to figure out the bench testing.....
