Hi, my backdoor will not lock when I press central locking. It makes a sound when the central locking is pressed. But it's just not locking. What could the problem be?

Hi, i have a ford mondeo 2015 sedan, it starts and drive sometimes and doesn't at time, i diagnosed it and certain fault codes showed up and also the park brake, abs, traction,engine light stays on
The diagnostic showed a problem with abs communication system and that the left motor had an issue
. . . Its not communicating with ecm/pcm
. . . Pam
On BCMII it showed code B1315
And also PCIM not comunicating with ecm/pcm either can these cause it not to start

When I connect the diagnostic tool, it cannot find the car's information automatically until I enter it manually. In addition, I have a problem with the CAN bus connection to the power steering, ABS, and the odometer. Often the engine does not start until I clear the errors. The ABS works without problems, the power steering also works, and the odometer works. What do you think the problem is and how can it be solved?

The ABS system is not working in the car and two lights are on the dashboard: ABS and ESP.

Die abs und esp Lampe geht manchmal an und dem esnsprechend die funktion des abs und esp felt aus
