Mach-e system doesn't sense key fob

ejohnnyt · Aug 18, 2024

I have installed a complete 2021 Mach-e drive system( battery pack, drive motor and electrics) in my 1965 Ford Falcon.
I cannot get the system to sense my key fob . Did I delete too many components? Also, will I need to use Forscan to
remove various modules from the programming? If I place the key fob in the pocket at the bottom of the console, The car
will sort of turn on but, the touch screen displays so many faults such as doors all open although I have deleted the door
related wiring.

There might be a couple of key sensors involved. In my ranger there's one in the steering column, one under the radio and the ignition switch is multi function security

I discovered that if I placed the key fob in a pocket in the bottom of the console, the vehicle will turn on but, the gear shift knob refuses to move and the the "on" light on the ignition switch flashes . I also find that I cannot gain access through the diagnostic connector although the two CANBUS circuits on the diagnostic connector both measure
124 ohms , which indicated both terminating resistors are present on each circuit and connected. Something is preventing the entire system from activating.

Wouldn't you need to see 60 ohms to indicate the canbus has the required 2 x 120 ohm resistors?

Geez ! You are right . What was I thinking ? Of course I should have detected around 60 Ohms .thanks ! Obviously
investigation is required.
