Jellybean Posted April 17, 2011 Share Posted April 17, 2011 I took the dash out to replace the MIL light Bulb, put it back together and the Spedo is not working. I took it appart again, re-tested amd the spedo is working on a short drive. I put the remainder of the dash back together and now the spedo is not working again. The solders on the unit look fine, what you guys think; re-Solder ? Is your ODO linked to the Spedo? Since it stopped working the ODO stopped incrementing/Trip computer Where do you get those Tosiba V2 Bulbs, plus the large 3W bulbs with a Green film over them , I presume the 3W illumate the clusters (spedo, RPM, Fuel,Water Temp) so if I want white I just replace the three bulbs?

stevie_b Posted April 17, 2011 Share Posted April 17, 2011 Is your ODO linked to the Spedo? Since it stopped working the ODO stopped incrementing/Trip computer Yes they are linked. The speedo output is directly connected to the odo input. Quote Link to comment Share on other sites More sharing options...
Jellybean Posted April 17, 2011 Author Share Posted April 17, 2011 Yes they are linked. The speedo output is directly connected to the odo input. Easy way to clock the car ,dissconnect your spedo Quote Link to comment Share on other sites More sharing options...

Samurai 20V Posted April 17, 2011 Share Posted April 17, 2011 When you did the Code 42 fix did you cut the right wires? This is what I did and it seems fine, odo and speedo working, no problem with the light as yet.. http://www.mkivsupra.net/vbb/attachment.php?attachmentid=47628&d=1164517403 Quote Link to comment Share on other sites More sharing options...

Samurai 20V Posted April 18, 2011 Share Posted April 18, 2011 Yes did that Then must be your speedo is faulty? Or is it making proper contact on the, none of the circuits broken? Maybe get another speedo to trouble shoot. Quote Link to comment Share on other sites More sharing options...
mellonman Posted April 18, 2011 Share Posted April 18, 2011 i had something similar when i done mine a couple of weeks back, found to be a bad connection on the od that link in the mile converter i just stripped out the old connection and re done it with solder in the wire Quote Link to comment Share on other sites More sharing options...
stevie_b Posted April 18, 2011 Share Posted April 18, 2011 my speedo is not working but my odo is? That's quite unusual. Probably a fault with or near the speedo needle. i had something similar when i done mine a couple of weeks back, found to be a bad connection on the od that link in the mile converter i just stripped out the old connection and re done it with solder in the wire Did that fix a faulty speedo? I'm surprised, but if you say it did then fair enough. Possible especially if the loom has been cut and spliced a bit, and has an ususual DSC fitted. OP: I'd guess dry solder joints on the speedo's circuit board. PS "speedo" not "spedo" . Someone having the same problem as you might not find this thread unless they search for "spedo" which is unlikely. Quote Link to comment Share on other sites More sharing options...
mellonman Posted April 18, 2011 Share Posted April 18, 2011 my speedo was still working but my apexi avcr displayed no speed which comes from the ecu signal, im not sure how its all wired in but thats what happpened striaght up guv !

Ah that makes more sense! Anything non-standard or unusual and the usual guidelines tend to go out the window. Quote Link to comment Share on other sites More sharing options...
Jellybean Posted April 18, 2011 Author Share Posted April 18, 2011 What do peolpe think, its the loom or the speedo cluster? Is it possible to test the Cluster (speedo,rpm etc..) if I disconnect it from the car? Quote Link to comment Share on other sites More sharing options...
heckler Posted April 18, 2011 Share Posted April 18, 2011 What do peolpe think, its the loom or the speedo cluster? Is it possible to test the Cluster (speedo,rpm etc..) if I disconnect it from the car? I still say dodgy connection from when it was all disturbed. You can test the speedo.. Is you have a frequency generator - which i have if you want send it to me and I'll test it.... Quote Link to comment Share on other sites More sharing options...

Last resort I will though When you say dodgy connection; you thinking the loom or the Cluster unit? Quote Link to comment Share on other sites More sharing options...
Jellybean Posted April 23, 2011 Author Share Posted April 23, 2011 Took her for a spin,speedo worked after i hit a bump and was intermittent with the bumps in the road; would I be right in saying it's not a soldering issue but either the loom connection or soiled contacts on the cluster unit Quote Link to comment Share on other sites More sharing options...
Jellybean Posted April 29, 2011 Author Share Posted April 29, 2011 (edited) Colin in SSI Cleaned up the Spedo sensor (gearbox area), spedo worked again until it got some heat in it. It seems to com on and off intermittent. What do you guys reckon spedo Sensor, I want to read the three magic words "easy cheap fix",? Code 42 is showing up --Starter Signal Circuit Heres my ECU Stock ECU and SARD Analyse ROM Analyse Analyse is an ECU set to provide alteration of high boost & rev control at high speed driving, and provides accurate engine control in various conditions, such as partial range, street driving, and engine idling.

Jellybean Posted May 5, 2011 Author Share Posted May 5, 2011 (edited) Anybody?, what are my next steps to trouble shoot? Edited May 5, 2011 by Jellybean (see edit history) Quote Link to comment Share on other sites More sharing options...
mellonman Posted May 5, 2011 Share Posted May 5, 2011 it does sound like dodgy wiring, i think if i was you i would diconect the analyse rom thing and reconeect it all. make sure there are now scotch locked connections, not the loom to have the problem but how the add ons are conected into that loom.

mellonman Posted May 5, 2011 Share Posted May 5, 2011 of corse then work your way back im sure you will find just a bad conection maybe near the od Quote Link to comment Share on other sites More sharing options...

stevie_b Posted May 5, 2011 Share Posted May 5, 2011 It'll probably either be a faulty speed sensor itself (unlikely), broken speedo cluster (possible) or flaky wiring between the speed sensor and speedo (most likely). Only poking around and re-making any joints that carry the signal from sensor to speedo will tell which of those it is. Quote Link to comment Share on other sites More sharing options...
