[Solved] Toyota Avensis T27 2009 D4D - VSC, ESP, brake (orange) and Check parking br lights are on

Hi, The VSC, ESP, Brake (orange) and alternating Check parking brake and Check VSC system lights are on (as in the attached photos). After a reset (removing the minus clamp from the battery) the problem disappears and everything is OK for a while. The problem occurs intermittently. The car was connected to the computer at the service centre (just then the lights were not on) and no errors were found. Has anyone had a similar problem and how to diagnose it further? .

Start by checking the battery.

The battery is new and in very good condition. I have consulted several mechanics. None of them told me anything specific, apart from one piece of advice to disconnect the clamps from the negative battery terminal for a while and so reset the computer. This operation temporarily removes the indication and the alternating messages: "CHECK PARKING BRAKE SYSTEM" and "CHECK VSC SYSTEM" but after a few weeks the situation repeats itself. I have another appointment with a car electronics mechanic for Tuesday 30 August, maybe he can help solve this problem? Greetings

Check your DPF I had such a problem and I have already solved it.

Mate a million percent you have a burnt out catalytic converter, the errors should be from the probe.
This is standard, and best of all the only way to get rid of it is with a new original underline catalytic converter.
If you buy a new one, but not an original, you will have the same thing again in a few thousand kilometres.
Does the car run a lot on the motorway?
