What to do when your ECU says no power?
Cut the 2 main KA plugs off the KA harness and splice them onto the SR harness. The MAFS and power steering sensor wires need to make it over to the front driver’s side of the engine compartment, use the MAFS and PS wires from the KA harness to extend these wires.
Why does the ECU light come on randomly?
Ill still post tommorow the wires in the engine bay, because the ecu lights will come on randomly, unless the ecu is on and the lights are off, maybe its in some kinda mode. Im not sure. I checked all fuses and they are good.
What are the symptoms of a bad ECM power relay?
A bad relay may cause the vehicle to crank, but not start, or sometimes not even crank at all. 3. Battery drain or dead battery. A failed ECM power relay can also cause a battery drain or dead battery. If the relay shorts it can leave power on to the computer, even when the vehicle is turned off.
How is the Apexi Turbo connected to the ECU?
Connect the remaining wires if you plan to use the onboard diagnostic CONSULT connector. The Apexi turbo timer is connected to the O2 sensor wire at the ECU to provide auto countdown functions. The Apexi AVC-R is also attached to the ECU harness for tachometer signal, speed signal, and throttle position.
