Towbar?

[Gina]

My daughter has a Rav4 on a 03 plate we fitted a toyota towbar a couple of years ago and for the last year it has been cutting out when pulling away, i have been told that the engine computer has to be told it has a towbar! Is this correct or is someone having a laugh!!!!!

Don't tell me you don't speak to the car!

Seriously, the engine management systems now run with so many minor voltage feeds that they seem to be thrown by anything. Is the car only cutting out when towing? Perhaps theres a wiring fault someplace??

I can't help beyond that cos both my RAVs use different ECUs to the original.

Dunno if it'll be the same on your 4.2 but on my 4.3 when I hitch up the caravan it self checks and the extra indicator relay in the back clicks for a short time then stops and the van lights up like a christmas tree with all the different lights going on and off randomly but you just press the brake pedal and that resets everything and all the lights then work correctly ;)

does the vehicle have traction control, if so, the engine ecu and body control ecu will have to be reprogrammed,so the vehicle wont stall, hope this helps.
