Vehicle wont start

Post by KWalker » Wed Aug 21, 2019 3:25 am

We have an F450 that wont start and initially required new PCM. We have replaced and programmed the PCM in it. Vehicle still wont start. We go to reset the parameters on this through PATS programming as per the steps but it advises security access denied. We also replaced the PATS transceiver on this as this was also a fault code and this has now been cleared. It still wont allow us in to this area.

We get two codes remaining
U2511 - CAN Communication BUS Fault
P1260 - Theft detected, vehicle immobilised

Has anyone encountered this issue. Everything we can find states that you need to reset parameters but it won't allow us in to do this.

Sort out the can comms issue. Not sure how the immo works on these, We dont see many in the UK. But the can is very important. All modules must be able to talk to each other to enable the conditions are right. In other words "everyone must be present before the party can start"
