How to Wire an ECM Relay

[@ADPTraining]

Yes it does. In fact I've seen some ECMs with as many as 7 separate grounds. Each feeding a different side of the system and separate sensors. As a rule O2 grounds are separate. A ground is a RELATIVE measurement. So, usually ground is Neg. battery terminal, but if you take a resistor or voltage divider network and take your ground point after it, then that's floating ground. It is called floating because the reference point is something else other than battery ground or Neg. Hope that helps.

[@ADPTraining]

Yes, usually to avoid ground noise. Naturally, since floating ground is not normal battery ground it is not prone to noise. This is why FG is used largely on radio circuitry.

Thank you so much and very helpful, have you ever seen any car manufacturer using floating ground for any sensor.

[@sivucit]

hi does ECM have multiple sensor ground or just one sensor ground. Also what is floating ground and how is it different from regular ground.

Sir mujhe bahut problems aati h mai yeh puchna cahata hu ki jo comperser ki relay mai jo ground e.c.m se aata h agar vo ground naa aaye to kya krna cahaiye mtlb kaise aage wiring diagram check kre plz sir muje batao

[@sivucit]

Also is there a reason why floating ground is used. Again thanks very much

Most cars today are digital coded, so that's not that simple anymore... Anyhow, that's no the intent of this video series. Thanks for posting.

Code P0656 is actuator code low voltage. Check wiring and fuses. Here's our Code Wizard Software that'll help with that... sites.fastspring.com/autodiagnosticsandpublishing/product/diyautomotivecodewizard

[@BetoMaxelectronic]

wich hardware work with this SW ?

[@ADPTraining]

Anything that meets the relay's current handling value, which is 40 Amps or almost anything.
