Speedo stopped working advice

[scotzman]

Hi all, speedo on my 350 2005 jdm has stopped working... pulled the fuses from the foot well and behind the battery and all intact,.. speedo shot up a couple of times but now nothing, not even the digital one, indicators i get sound from..... what would be the next check after the fuses... thanks for any help..

[Jetpilot]

If its using a speed chip converter my money would be on that, I bought two that never worked properly.

Speedo is controlled by a fuse in the foot well. Double check them to start with.

 

If the pod has stopped working too the white box behind the AC controls might be knackered?

[Aashenfox]

I was going to suggest swapping the cluster from another Z just to check, it's a 2 minute job and would eliminate the easiest part to change (and source), though if you change cluster you might want to have the miles re-programmed to be correct. But since the digi isn't working, maybe it's something else.

Hi Marz, had the dash out a few times to fit reverse/front cameras/double din etc, but speedo had stopped before i did all that, checked all fuses in the footwell yesterday and all seemed ok, maybe i should double check them again as suggested as most people with this problem when they re-seat the fuses they have a bit of luck.

Where abouts does this chip go? Mine has the same problem but ultra-intermittent (normally on hot days/after a long drive).

Im guessing its more than a 2 min job in my case with the cameras the cluster is JDM and still in KLM, there is a speedo de-limiter hanging iin the passengers footwell but im guessing its not related

Its not that the car needs a reboot as everytime i get in there is no speedo

Hi Jet..I wouldn know about the speed chip converter unless its a De-limiter which i found hanging in the passenger footwell.. this is the same as what i found.

I swapped mine from a US one in miles to a Euro one in kms without any issues whatsoever. In any case, pop the ignition trim out (ring around the ignition), remove the lower steering column cowl, undo 4 bolts and a plug, that's it. Pop the other in and just see if the needle moves, you don't care if its miles or km to see that the needle moves I suppose.

Hi Aash, do you mean disconnecting the SLD and putting the original harness block back in ie eliminating the sld... or are you meaning another cluster

Edited April 5, 2017 by scotzman

Another cluster. It's a relatively quick test to eliminate the actual speedometer mechanism, but like I said, it's a fairly long shot, given that the digi doesn't work either.

Unfortunately i dont have another cluster to try, i could buy another second hand one Aash then would i not be better going for one with MPH

[Aashenfox]

Up to you I reckon. If I were you I'd probably get another JDM one, they do have MPH on them on the inside of the clock facia, don't they? I say this mainly to avoid computer issues, but just for testing (literally to see if the needle moves), all you need is a Z friend with any cluster at all, 10 minutes to swap over and see if the needle moves, 10 mins to swap back, no biggie. The funny thing is I have a spare cluster which I would gladly give you for free, but it would cost me 10-15 quid to send it to you and take probably around 10 days to arrive... if you want to do that, shoot me 15 quid and I'll send it over. It's in an awful state visually, but mechanically, it works fine. You could use it to experiment with facias and lighting after that I guess. It;s a US unit, with white euro facias (which don't match light locations, of course, this is why I changed it), plus the moron who did this 'work' on the original cluster clearly lost the mask that goes behind the facias with the result that when a light comes on, the whole gauge lights up red and you can't really tell which bulb has come on. It;s quite funny really when you look at it and think that someone did that on purpose and was probably happy with the abortion of a result.

Does your speedo read in kmh or mph?

Hi Jet speed on digital reads Klm

[Jetpilot]

The digital gauge will mirror the speedo, presuming they both show the same speed and is it that in mph or kmh, not what is written?

Digital one reads in KMs and face dial has the mph... if that makes sense.. I deally if im gonna have to buy a second hand cluster obviously i would buy it in MPH as i was gonna buy one anyhow..

No it doesnt, so are you saying they read differently, or just speedo has a mph sticker and digital says kph.

[Aashenfox]

I think he means the facia and the digital are both primarily kph, however, the facia also has mpa on the inside scale (dual scale speedo facia).

[Jetpilot]

I dont think the jdm speedo has mph from memory of mine (but i could be wrong), but yes, i know what you mean and thats what i am trying to establish to ascertain whether there is a speed chip converter somewhere in the mix.

[Aashenfox]

I think you're right, the only JDM cluster with MPH that I can find after a fairly extensive search, is the Nismo article for 800 quid from Japan.

 

therefore, I would agree that if he has a facia that shows mph and digi that shows kph, there must be a converter (and a change of facia) in the mix.

 

If you can stomach that price, scotzman, that's the one to get!!

 

 

Here's a second hand one for a little less.

When you buy the chip converter it contains a little mph sticker you just place over the kmh, some people just blank out the k, that was also one of the stupid sva rules, you couldnt use the mph sticker as it wasnt lit at night so you might forget your doing mph not kph

[Aashenfox]

Lol. Just, lol.
