I just had to remove an aftermarket alarm to make sure it wasn't affecting the vehicle. Her is the DTC I'm left with. ===BEM DTC B2930-60=== Code: B2930 - Transmit Data Line Open Circuit or Short to Ground Status: - DTC Present at Time of Request - Malfunction Indicator Lamp is Off for this DTC Module: Body Electronic Module ===END BEM DTC B2930-60=== Here is the recommendation from the Ford Manual. B2930 Transmit Data Line Open O/C or S/C to Ground, Check continuity from Circuit or Short to Ground External Fault BEM J1/8 to TILA J6/9. Check wiring and TILA. Ive buzzed out between BEM J1/8 and TILA J6/8. It appears open circuit between the BEM and the white connector J6/8. To double check I tested another connection between the BEM and the TILA and got open circuit. Knowing this was odd I decided to put a tone down the line like you use in comms to cable trace. Now the funny thing is the tone is present on the pin. Now if I plug the TILA socket in I cant get it to buzz out when its connected but no when its not connected. Weirdest fault I've ever found Link to comment Share on other sites More sharing options...

Just like when the engine doesn't start, your first check should be the battery. Low battery power may be the cause of this situation. Another related possibility is that the connection from the battery to the starter motor is loose, corroded, or otherwise damaged. Tightening or replacing these connections or cables can solve the problem. Link to comment Share on other sites More sharing options...
FordXR6TPerth New Member 17 Member For: 5y 8m 24d Posted 20/03/23 12:38 PM Author Share Posted 20/03/23 12:38 PM Ok So Battery Has been checked and replaced beforehand and is operating correct. The starter motor works and cranks the motor fine. As per the above fault it ended up being the BEM Module. Got a new BEM Module but still no start. Now Getting the original 2 DTCs P0237 & P1385 Link to comment Share on other sites More sharing options...

I would suspect a faulty sensor on the bus(not necessarily one of these 2)or a wiring issue.I would plug in a good diagnostic computer and check live data and see if anything is out of spec.

I have Forscan and can read live data but don’t know what I should be looking for. Should have been a mechanic instead of an electronics technician.
