Hi, I have a 2012 mondeo that says immo active on the dash. For the life of me I can't find a fault. Can bus wires are 60 ohms. Can talk to everything. I do need to rescan again for dtcs. Even managed to borrow pcm bcm barrel/key pats reader from another car no different. I'm at the point it's something in the wiring somewhere. Has anyone seen or heard of anything that will stop it from cranking and come up with immo active?

Is “immo” the immobiliser?
Sorry, have no answer for you.

Had another quick today. Turns out I have no coms with pcm or tcm. Have coms to abs module. Is there a pcm pinout available? Want to check the powers and grounds at the pcm and also the com wires back to the underhood fuse box. Seeming like I'm missing one
Cheers |

I have a 2010.5 pcm wiring diagram not able to upload it here due to size - 1.5 mB.
Check integrity of connectors on the GEM ? I have heard about washer fluid creeping up from the sensor... FYI I'm a DIYer not an expert. |

Turns out I can talk to the tcm and pcm. But can’t talk to rcm module. This is the codes I pulled out
U015100-lost coms with rcm U042268- invalid data received from bcm U041568-invalid data received from abs B10a202- crash input B10a215- crash input U045262- invalid data received from rcm U041800- invalid data received from brake system control module Turn ignition on still comes up with immobiliser active My question is. Is the rcm apart of the immobiliser system? |
