VX upshift light
 

Is there anything that would cause the VX upshift light to not work other than the light being burned out?

Its a simple ground signal from your ecu. So it could be wiring, or (less likely) the ecu. When I did my ef swap, I ran a wire from ecu pin d18 to the hatch light.

If the CEL is on, the shift light won't function either.

Has it suddenly stopped working?

The CEL isn't on... but it works (it turns on when I start the car). The upshift light just doesn't work for me at all.

I wonder if a previous owner cut the wire b/c it was annoying or something.

So the upshift light does not come on when the instrument cluster goes through it's bulb check?

Then yes, it's either a burnt out bulb or cut/broken wire. :thumbup: :D

Just today I was wondering the same thing regarding my non-working shift light, so I took out the bezel, and looked at the back of the cluster. Not much to my surprise, one of the wire-clips wasn't plugged into the back of the cluster. I plugged it in, and now the shift-light works! Yay! Never had it work before, so hopefully using some guidance from it will improve my shifting for better MPG.

My guess is the previous owner got annoyed of it.

guess what I'm doing in a few minutes?

My predictions:

• You will check the light during the bulb check
• You will check out the bulb itself
• You will check the back of the cluster
• You will check the wiring to the ECU
• You will get your shift light to work

Lolz

well, it wasn't the connectors behind the cluster. Guess I'll be checking the ECU later.

I did manage to replace the o2 sensor though. It actually responds a lot better already.

Did you happen to check the light bulb itself with an ohm meter when you had the cluster off?

Mine didn't work until I replaced the O2 sensor. Then it worked fine.

Oddly, I didn't see a series of light bulbs in the back of the cluster. I think I saw only 2 in that general area, which is weird considering there are approx 4-5 different dash lights there.

Guess I can remove it tomorrow and see.

Oh, I need to figure out how to remove the brake light in the top of the hatch wing thing. I removed the cover, and the bulb wouldn't budge. I need to fix this before I can pass my safety inspection.

Getting off topic but...

Matt, what source did you buy your new O2 sensor from, and would you recommend them? It seems people have had issues in the past with getting the wrong/defective L1H1 and I need one for my VX as well.

Thanks!

He got one with the engine he bought imported from japan, :p

And another used one he bought on h-t for 25 bucks, as I remember.

actually, the one that came with the engine was cut 1cm from the o2 sensor. The one I got on ebay for $25 was a POS.

I bought one for like $150 on ebay a year or so ago.

I'm really hoping it's just not the placebo effect, but I swear that my acceleration has drastically improved since I put that o2 sensor in.

1cm is a lot of space, man...

not enough... I might still have it if you want it :P

:D

okay... I'm a doofus. I removed the cluster today and there is no bulb in the upshift light area...

no bulb as in, "oh, geez, someone took it out" or "I don't see where the bulb would go for the shift light"?


:confused:

as in, "oh geez, someone took it out."

i'm going to take a bulb from my spare cluster and throw it in there.

Ah, congrats then. Be sure to check that the other bulbs are there too, then.

So I put some spare bulbs in today.

Now CEL wont' turn on during light-check, and my turn signals don't work. My guess is that I blew a fuse, but they all appear to be fine to me. Guess it's time to break out the DMM.
