Headlights Flash No Central locking or Electric Windows

Farmer Fred · Jun 7, 2013

Hi All
Please has anyone got any ideas on the fault below

With engine running
Headlights and dashboard flashing on and off
Central locking stopped working
Electric windows stopped working
Headlights and side lights will not turn on or off with switch
Clicking under passenger seat which I am sure is the seat relay, if I push the seat forward button the seat move as the relay momentarily clicks on.

With the engine switch off and the keys remove from the ignition
Relay still clicks under passenger seat
Indicator and high beam lights flash on dashboard only
Dashboard display flashes Diagnostic Mode

The BECM has gone mad and/or the carpet is wet in the drivers footwell or, hopefully, the battery voltage is low.

Hi All
Thanks for the advice. I have just read a post for a different fault by Mr Noisy where he says try disconnecting the battery I have done this and all faults have cleared.

Don't know if it will last but it seems a reboot of the BECM has done the trick

Thanks Datatec for the tip on the footwell I have noticed this on a couple of cars which I have stripped the loom connectors in both n/s and o/s were corroded due to water

Do you know if any of these connectors would stop the key fob operating the central locking. I have tried to resynchronise the fob but it doesn't work this is an old fault but would be nise to cure it

If the LED on the FOB lights but it will not sync, I'd be looking at the RF receiver.
