I have a JDM cluster in my EG 4 dr and my damn tach and speedo dont work. I have no idea why and I dont know what to really check. They both worked at one time with that cluster.

Is there a way to find the pins on back of the cluster and hard wire them to the dizzy and/or ECU?

I need a helms!!!!!

Check your fuses and make sure you have good connections

ham

fuses are good and the connection dont seem like there could be any bad ones. No corrosion on everything, all connections full seated.

i have a VSS code which would mean the ECU is not getting a signal from the VSS......... correct???

because if it was, it wouldnt have a code, the ECU doesnt care if there is no cluster, as long as its getting the signal.

Maybe your VSS is causing you to have no signal to your tachometer. Why not replace your VSS and see if that helps. Either way, you need to change it.

ham

how do i get signal to the tach?

Deemeetree

The blue wire from the distributor.

ham

soooo do you know where i can find the wiring diagram for the back of the cluster???

Deemeetree

It's the same colored wire that goes from the distributor to the back of the cluster.

ham

oooooo. ok i can figure that one out. i bet that there will be continuity from that blue wire to the one on the dizzy. (my luck).

now for the speed sensor. signal from the vss goes to b10 on the ECU. Then what goes to the cluster?

BatuKing

did you check to make sure there is continunity in the cluster? the connector for the gauge cluster is the Yellow/blue wire which is the same as the VSS wire.

just trace it back from the speedo

woah i didnt know that. so the vss signal goes to the ECU then to the cluster and the tach signal from the dizzy go to the same wire ??? i think its b2 on the cluster

ham

waiiit. that cant be right. 2 signals cant go to the same wire.

BatuKing

NO.. the VSS wire splits.. one wire goes to the Gauge cluster and another goes to the ECU, but the colors are the same.

It doesnt share the wire with the Tach the only wires it shares with the tac is the ground and Power.

ham

i got the tach working. there is continuity from the middle wire on the vss to the matching pin on the ECU and on the matching pin on back of the cluster. there is also power and ground at the VSS which I checked with a voltmeter. STILL NO SPEEDO!!!!

one thing is i may be unsure of the order of pins on the VSS. ive got black-ground, orange- +, and the middle wire is signal. seems like everything is right.

BatuKing

did you check for a ground and power for the speedo ?

ham

negative. i will check that later. know where i can get a schematic for the cluster?

i took my vss off and put it on another car and it worked. but i stil have the vss code. its such a simple circuit but yet so confusing!

i give you credit for getting my tach to work btw. thank you.

BatuKing

Email me and I will send you the pages for the helm to check the speedo.
