  • Not Soarer but similar - Mk3 Supra digi dash problems

    Hi all,

    Been a long time. Still got the z20 but it's in pieces awaiting a v12 heart. So whilst that is taking years, i thought i'd buy a mk3 supra to keep me occupied. It was a 1G-GTE manual and swapped in a 1JZ for good measure. The only issue is now the digi dash is not functioning at all.

    When you turn the ignition to 'on', the dash lights for a split second but that's about it. I've tested the dash plugs to check for 12v and 5v inputs but without a wiring diagram, i'm pretty much checking naff all. There are a few 12v and 5v feeds though. The fuses are all fine too.

    I was under the impression that the dash is independent from the ecu, so the engine swap shouldn't stop it at least from illuminating ?

    Any ideas are greatly appreciated.

    All the best,

      Find a diagram, test for power.

      If there is power where power needs to be and its still not working, then you have a bad cluster.
