I have a 2005 RE 300 with the DT 466 . We have been having issues with the bus burping and sending the key pad for the transmission to clear it self . The driver will shift to neutral and back to drive . The only code I get is a 622 . I found while it's running I can grab the wires in the box and make it hiccup and then run smoothly . So I had another issue with the sister bus . I rewired the relays . My question is when I check the ECM and Idm they show power to them all the time . Is this normal ? When I plug them in I don't hear a click ? Then when I plug the relay for ignition with the key on I then hear the relays click and the injectors come on . We have also been dealing with a draw on the batteries . Thanks
yes they are hot all the time they get fed from the clean power harness right from the batterys the ecm and idm supply the ground to the coil inside the relay to activate them
