Doing my Hybrid wiring and have a question about wiring the safety switch. My question has to do with the ECM Pin B10. Can someone tell me what kind of a signal this pin is looking for?
It won't prevent the ECM from starting the engine. The P/N input to the ECM is mostly used in the IAC routines. For when shifting into and out of gear. There are also two idle speed tables, one for P/N and the other for in drive.
The last bit is that when in P/N there is a SA modifier.
Usually the biggest issue with no P/N switch is that the engine stalls when the trans is put into gear.
