No brake lights

[Andrewp2510]

Good afternoon all. Currently have a 2011 berlingo with no brake lights working. Have checked all relevant fuses, bulbs and brake switch for continuity and everything seems good. There is just no power coming through to the plug that attaches to brake switch. Do I have to check every fuse or just the relevant ones. Any ideas on we’re to start next. Tia Andy

Hi there, If you unplug the switch, the brake lights should default to "on", if not then you may have a BSI fault. (Body Systems Interface computer)

The switch goes there and the BSI operates the lights for you. It's not like a conventional old system where the switch powers the lights.

Have attached the schematics for you to look at. Also a legend for item numbers and wiring & plug colours. Plugs are noted as follows: 14V NR would be 14 pin, black plug (NoiR)
