Welcome Visitor! Please take a few seconds and Hi , I installed a Yaris EPS in my old-timer car but I am not able to bring it to life, ECU and Drive train from a Yaris MK1
I wired it up as on your wiring diagrams but nothing occurs, when I put ignition wire on pin 6 the ECU clicks twice , drains a little current during the clicks (relay?) and then no more drain. But when I DISCONNECT the ignition wire from pin 6 the ECU clicks one more time and a little permanent drain appears (like a relay consumption) witch is not normal (drains the battery permanently till 0) , finally when I disconnect the main + wire ECU click again (relay falling?) and then when I connect main+ again NO more drain.....
I tried 12v signal on pin 5 but no change...
I replaced the ECU and phenomena is the same...
Any idea? and hoping for help
sorry for my bad English
