1992 VP Cooling Problems

If code only 12 continues to flash your ECM has no faults stored. If a fault is stored the ECM will start flashing fault codes. Each fault will be flashed 3 times starting with the lowest then moving to the next one up. When all fault codes have been displayed the ECM will start again with the lowest. If there's only one fault it will flash its code until you remove the ALDL earth jumper.

Yes a level 3 dash is a path you don't want go down unless you already have one fitted. My level 3 has a BCM which you won't have. Good ones, with all 3 screens working, are expensive these days plus there's a fair bit of wiring work and a level 3 will find dormant faults wherever they exist in the control system components.

 

Finding a patch loom I'd think would be difficult now anyway. A former member used to make them but he moved overseas so I heard.

 

It is. Howard Instruments can do it in Melbourne for a Level 3 cluster but it was pretty expensive because of the trip computer. Why don't you just make a note of the old and new speedo speedo readings and work out how much you need to add/subtract. Use your money to get the car running, you can always adjust the speedo later.

 

Yep speedo can be swapped over...dash cluster can be pulled apart into 5-6 pieces.

Only downfall is if you want matching vp gauges as vn,vp & vr/s have different colouring if you know what you're looking at which is why most prefer swap whole cluster over as one.
