I am trying to disassemble a cluster from a 2008 Honda Accord, to replace a CEL lightbulb. This is as far as I got without forcing things and I'd rather not break it. The rear board is loose, but will not separate from the cluster. The white latches that go through it aren't holding it.

I suspect the next move is to separate the gauge needles from the servos and pull the "face" of the cluster. Does this sound correct?

My searches haven't yielded anything on this type of cluster. All the other Honda ones have separate lightbulb holders, easily accessible from the outside, as God intended.

Thanks.

Yup, take the needles off.
 
Maybe those nuts on the heat-sink looking things?

Thanks, but I can see the other end of those fasteners and they don't hold anything on the other side.

The board does float and only seems to be held by the four gauge needles up front. But they don't seem to budge when I pull on them.
 
Mark their zero spot all the way counter-clockwise with tape and a mark before you do or they won't read right upon reassembly.

put your purse down and pull on them. :flipoff2:


in all seriousness, those look just gmt800 clusters with the needles on the junk servos. do you have plastic door button poppers? I like the really wide one for this purpose.

FYI you're going to need a way to be able to put them back on in the right place.

If they sweep on power up you may be able to use that to get them right, or you'll need a scanner to be able to command a position for them. (Or some other type of shenanigan)

No, I don't have those. I'm trying to figure out which gauge I need the least, to try first :flipoff2:

They all seem to have hard stops. I suppose that should make alignment easy. No sweep on power-up. Thanks.

Last one I had apart was a gmt800. I just plugged it back in, let the servos sweep, and pushed the needles back on at 0 and 14v.

It worked for another 60k after that, and the speedo was within 1mph

A looooong time ago I may or may not have pulled the speedometer needle off a Mustang LX cluster and repositioned it so it would read correctly after I did a gear swap and sent it down the road. :laughing:
 
The needles came off and the board separated. The lights are lit by tiny LEDs soldered into the board. I sure hope the problem is there and not into the ECM or car wiring.

Anyway to find put which pins on the connector are to the cel? Or is there another dinky module on the board that sends power to the cel?

Anyway you can just put 12 volts to the circuit and see of the led illuminates?

I’ve had some luck using a plastic fork to pry needles off without doing any damage to the cluster fascia


edit looks like you got them :homer:

... not sure those led’s run on 12v ?

Many of them run at a much lower voltage and 12v will let the magic smoke out ...

I found a cheap cluster on Ebay. Hopefully it will do the trick.

But yes, I suppose I could trace the connections and find ground and power in the connector.

Thank you all.
