Hey LEONARD JUL,

Do any other interior lights not work when this fault occurs - Cruise control, hazard switch etc?

Any particular time that this happens?
Always on start up or is it random?
Do the lights come back on or do you have to cycle the ignition?

Regards, Joe

Hello Joe, Many thanks for your response. I addition the cruise control switch does not work and the AC rear control. Also the sun visor light is not functional. The navigation system appears randomly without turning on the ignition. The light of the transmission shift bar never appears.

Hey LEONARD JUL,

Does the radio function okay and it is just the display cutting out?

I would first check the interior light fuse as explained in the fault diagnosis guide attached below.

Please can you remove the navigation display and check the power and ground to the unit when it is on and when the fault occurs?

Are you losing power?

The accessory circuit may be the problem.

Let us know how you go with these tests, any questions to clarify anything please do not hesitate to ask.

Regards, Joe
