Dash Lights Flashing

[JoeHummer]

Okay, now this is worrying me a lot. 3 times now i have seen the battery light, the lock light, the seat belt light and the low fuel light come one and the needles (except for the RPM and Speedo) drop to 0. No other lights are flashing and the lights on the inside are not flashing. Just that is happening.

Any idea what it is before I take it to the dealer for help? This is really bugging me.

Thanks.

Not in my hummer, but have seen the exact same thing happen in a chevy pickup. We found 2 things wrong at the time, so not sure which it was, but maybe you can narrow it down... 1 we were doing a stereo install, and had tapped into a bad gound wire, second was that the little harness the connects to the parking break was slightly loose.

Hope this helps

Only thing I installed was the ipod adapter that was plugged into the XM spot. I did not touch anything else.

Anyone else have this issue????

Interesting, I installed the ipod adapter last week also. 3 days later, Friday, my abs, brake & trac cntl lights all flashed and the chime sounded 3 times then it went off. Has happened to me 4 different times since. I already had an appointment scheduled for this morning at the Hummer dealer, so they are taking a look. I did not mention the ipod adapter, so it will be interesting to see what they come back with. Cant' imagine they are related, but who knows.

Joe,

This happened to me twice this weekend. Mine is a brand new 2007 H2.

As you know from the other thread (Ultimate iPod Adapter), I have also installed the Nucleus X2i iPod adapter. As mine is a brand new car, and I installed the ipod adapter immediately after purchase, I wasn't sure if it was the car or the adapter.

This weekend, I uninstalled the iPod adapter. As the electrical problem was intermittent, I was going to drive around for a week or so and see if it happens again without the Nucleus adapter.

Keep in touch so we can let each other know how it goes. My hope is that it is the adapter and not the car!

I'll also post on the Ultimate iPod adapter thread.

Do those Ipod adapters require any type of ground?
The problem sounds a lot like an intermittent ground problem.

[LV_H2]

I agree, it sounds like a ground problem.

Unfortunately, the adapter comes with a Y harness that simply splits the XM connector for hookup to the XM tuner and the iPod Adapter. No actual ground wire for the adapter.

There is, however, an AUX input (RCA jacks) on the ipod adapter, and there are two "hot power" wires from the harness for connection to an AUX device. I taped these wires off with electrical tape upon install. Maybe these are the problem.

I will be calling the manufacturer tech support to ask them for assistance.

Thanks for the input.

I have also installed the Nucleus X2i iPod adapter and I am now having the same random flashing light problem with my dash lights...

[JoeHummer]

Sounds like the ipod adapter is the problem.

Mine is still doing it (5 or 6 times total now). I did the same tape job on the power wires and I have nothing installed in the AUX spot.

Let me know if you get any help from Tech support.

[LV_H2]

I probably won't get to call them until Thursday.

Feel free if you want to give it a whirl:

Mine does the same thing I have been in touch with A.I. and the tech are testing the code to see if the last changes are the problem. I will be talking with them again in the next day or so.

[JoeHummer]

vlxjim - Thanks. Let me know what they say. I hope this doesn't mean we have to send them in for upgrades and be without them for a long period of time. By the way, what version do you have? Mine is 5.03.
