instruction to re-boot on board computer

I’m driving a hire car at present, it’s a Toyota something-or-other 4wd automatic with the diff-lock as a dashboard button.
I came to try the diff-lock and the engine warning light came on (Orange light engine symbol ) and stayed on.
I rang the hire company and explained the fault, who said the “on-board computer possible had a glich and needs re-booting”.
“Take the car to any garage and get a mechanic to re-boot it for you”.
Instead I emailed a garage where I normally have my car serviced and ask what it involved.
Reply: “Just disconnect the battery and leave disconnected for 20-30 seconds”.
Problem appears to be solved. New one on me.

They probably left off the 'ctrl', 'alt' & 'del' buttons as a cost saving!

Re: instruction to re-boot on board computer

I did some repair work to my car last year which involved having the engine in bits, manifold and throttle assembly off etc. Got it all back together but forgot to clamp one pipe to the air filter just before the MAF. It not only ran like a dog but caused a gearbox fault to be raised. Fixed the air leak, disconnected the battery, reconnected, gearbox fault gone  Cool Not had a problem since  Smiley

Re: instruction to re-boot on board computer

If disconnecting the battery just make sure you know your radio code if it's one supplied with the car.
Also what's in the ECU ? I Presume the memory is fixed and the various sensors check against the memory to ensure everything is running within certain limits and any problems showing up on the dashboard light but I also recall reading that loss of battery power to the ECU would result in a loss of some information for efficient running of the car and it would take some time for the ECU to relearn this ?

Re: instruction to re-boot on board computer

In older cars (such as those made in the 90s when flash memory wasn't really around) there wouldn't really be a way of reliably reading and writing memory that could be stored long term with a battery disconnection so it would make sense for the ECU to be hard coded with failsafe values and then to possibly re-learn.

Good point, but it's a Hire Car, if it dosn't work they replace or send out a mechanic to fix
