Hey guys, my Ford just threw the B1681 code, and from what I’ve gathered, it’s related to the PATS (Passive Anti-Theft System) transceiver module. The car’s not recognizing my key properly, and it won’t start. I recently had a new key made, so I’m wondering if the transponder wasn’t programmed correctly, or could there be something wrong with the transceiver module itself?
I’m also worried about possible wiring issues between the transceiver and the ECU. Has anyone else dealt with this code? Should I try reprogramming the key first or look into replacing the module? If anyone has had a similar experience or knows how to troubleshoot this, I’d really appreciate the advice.
