Dash Lights (vsc And Trc Off )

[LoSLucifer]

Hello.

I have some lights going on randomly in my car. VSC and TRC OFF suddenly starts glowing.

I have to turn the car OFF to turn the lights off. I do not notice any changes in the car when this happends..

Tryed to get some error codes out but my OBD dont show any error codes...

pleace help.

Does the TRC switch have any effect on the display?

[LoSLucifer]

No. If i push the buttons for on/off it does nothing. It stays on all the time if it first have turnd on. i have to turn off the car to get rid of the lamps.

Then i can drive for a long time ( many hours ) or 10 min before it turns on again.... completly random.

Any tips?

I think that these lights must com on with the slightest problem, mine came on when glow plugs needed changing

[gazza1286]

Unusual dash light behaviour on some Toyota models is an indication that the alternator isn't charging correctly. Could be an early sign?

I had the same problem as Old Fiver. TRC, VSC and Check engine were on. An obd2 tester gave the answer for the glow plugs. Switched them, all OK.

I recently had these two lights on and when I switched the engine off and restarted they were off, but after travelling a few yards then braking they were back on. I turned out it was the fuse for the brake lights had blown. maybe there is a problem with the electric to the brake lights Mine have been ok since replacing fuse.

Check the stop lights. My friend had this erratic problem a year back, when he owned his Avensis estate. Read the following:-
