MIVEC CA4A AUTO VSS PROBLEM

[ruzainironi]

Hi everyone, I am facing a problem with the VSS signal loss which is causing the pivot speed meter to not work.

I have tried to find the problem using the wiring guide so far everything works according to the guide. I have not found a solution to resolve this issue. I have also changed other meters but the issue is still the same.

Can help me about it.

What is the issue exactly? And please show us how you wired it. The CA4A Mirage is similar to the early EVO, so perhaps the reed switch is bad.

Previously the pivot speed meter could get the km/h speed from the meter. but now it doesn't work.

I have checked the reed meter and found that there is no problem about it. Follow this image I have done tracing of wiring and found all functioning without problem. Make no clue to fix this problem.

I don't get the situation. Does the unit get powered on? So the speed meter was working properly before and then suddenly stopped working? If so, most likely the unit is bad.
If it gets powered on but only doesn't show the vehicle speed properly, then make sure that you are wiring it with the right wire. Are you sure that you cut the wire to ECU pin #66 and sandwiched the speed meter unit?
