Volvo Penta ql trim Tab system.

[MLH]

The trim tabs are not working and all LED lamps are flashing on the display. Does anyone have a suggestion of what the problem could be?

Are these the intercepted style tabs?

Yes.

Yes.

In that case my next question was going to be, which lights are flashing? As you can see from the post above, this indicates the problem.

Thank you. However, the problem is that all lights are flashing simultanously, and as far as I can see, it is not described in the manual, or what I have been able to search for.

The problem is that all lights are flashing simultanously. I have searched the manual, but it does not describe the issue with all lights flashing.

In that case I’d try unplugging the control panel from the control unit and then recalibrate the system on reconnection. If all the lights are flashing it would appear to be all the fault codes at the same time.

Not really. You could contact a dealer, the VP website is not the most helpful. Local dealer | Volvo Penta

Volvo QL Trim Tab System Problem
I had a similar type of problem (but not all the lights flashing), see link. I couldn't find any help/advice so took a punt and bought a new control unit and it started working fine. The controller was just over £100 I think.

Just a thought but there seem to be two power supplies, main system supply to the control unit and another supply to the control panel from the ignition. Have you checked the supply/fuses at both these locations? If the control panel is getting power but the control unit isn’t then it could cause your problem.
