primordial how simple is it to do an ecu reset??

thanks

This is how I reset the ECU on my Subaru. I image the same will work. Its not the proper way to do it, but its by far the simplest. Its the simplest because I don't remember the other way.

How to reset the ECU, battery dance styles.

NOTE: Do this on a "cold" engine. Leave it sit overnight and do it in the morning.

1. Disconnect the negative battery terminal cable for 45-60 minutes.

2. Reconnect the negative battery terminal cable.

3. Turn off all your accessories.

4. Start the car, but DO NOT touch the throttle at all.

5. Let the car idle for 10-15 minutes, or until the car is at normal operating temperature. Again, do not touch the throttle.

6. Turn the ignition key to the "OFF" position. That's it.

take the battery off and leave off for 24hrs

but sounds like you have an electric short some where. might be best to take it to an auto electrician

Yeah as Mitch said - your best bet is to contact an auto electrician.

There's almost no way the ECU can decide to start the car itself... its an electrical circuit that is most likely shorting somewhere and starting the car... Just thinking though, how could the car possibly have run the starter motor for the specific amount of time needed to start the car? If it was properly shorted it would have grinded the starter motor into oblivion when the car started and the starter kept going..

Very odd problem! :P

Well it sounds like you're onto it now anyway. Get it removed. It's probably more of a security risk than a help.

whatever you do, do not cut the handbrake wire, unless you know how to remove that alarm, and get the car sorted. ( cutting the wire will disable the car and you won't be able to start it. had this on my old car took me ages to find)

if not take it to an auto electrician, or call a Mobile alarm guy and they should be able to take it out.

      Tein Circuit Master- rebuild worth it?

      By MBS206 · Posted

      If they can dyno them, get them dyno'd, make sure they're not leaking, and if they look okay on the dyno and are performing relatively well, put them in the car.   If they're leaking oil etc, and you feel so inclined, open them up yourself and see what you can do to fix it. The main thing you're trying to do is replace the parts that perish, like seals. You're not attempting to change the valving. You might even be able to find somewhere that has the Tein parts/rebuild kit if you dig hard.

      Best place to order Authetic R32 Parts in Japan

      Can you also make sure the invoices on the box (And none exist in the boxes) are below our import duty limits... I jest, there's nothing I need to actually purchase and order in. (Unless you can find me a rear diff carrier, brand new, for stupidly cheap, that is for a Toyota Landcruiser, HZJ105R GXL, 2000 year model...)

      Murphy strikes again! Nothing at all would have gone wrong if you had the tool kit in the car! You'd have just found the clamp loose the next time you went to touch it...

      Blue slip

      By MBS206 · Posted

      I have been being VERY quiet about what you're alluding to, as it is something that ticks me off... The number of cars from factory that run coil overs is HUGE! Most of them these days do... The other part that annoys me, is people saying "Well all the incabin adjustable suspension is illegal by blah blah blah"... If that's the case, then why can I buy a car brand new that can do it if, FULL STOP in cabin adjustable suspension is illegal...   Also, I could just chuck some aftermarket shocks in my car, throw the stock springs on, after my blue slip, dump my super low springs back in. Same shock and spring style setup... Hell, they could also be the same colour springs etc.     I'm voting, BlueSlipper didn't want to touch the above car for some reason. Whether it be some sort of bias against the car, the owner, them maybe having previously done dodgy shit and now they're being super careful in case they get slapped in the face by the Gumbyment again... Find a new blueslip place.   And can confirm as you had said, yes there are holy bibles of vehicle heights, and all sorts of other suspension stuff. Heck your run of the mill mechanic, and tyre shop has access to all of that stuff. It's how they do wheel alignments...

      Funny story Heading to Sydney this morning on the HWY there was some slow traffic, so I gave it the beans and midway through my overtaking "power run" I lost all power It seems that I missed a hose clamp,  and the MAF and filter went WiFi To make this more problematic, the little tool kit that lives in the boot, is sitting in the sun room at Goulburn......LOL Luckily for me I found a bit of steel on the side of the road that could be used like a rusty and bent flat head screw driver to tighten it up enough that it got me into Sydney, it is now all tight like a tiger with the aid of a 8mm socket Note to self: Use my brain and double check stuff, and always keep that little tool kit in the car for when I have a brain fart
