Trekka central locking and hazard light problem

Hi, I have searched and found several posts with this problem and no replies or solutions so trying my own post.

While driving and at random times the central locking starts to cycle and the hazard warning lights come on. Pressing the switch stops this for a wee while but it will start again.

We assumed this could be linked to an inertia switch fault but no such part is listed.

We have wiring diagrams but can not find a link.

Please, if anyone has a solution please let me know.

Many thanks in advance.
