Solution for Locked ECU from SCT Tuner

Here is how it all began...

I was attempting to return my vehicle to stock with my SCT tuner (X3/SF3) and the process had an error and failed to program my vehicle. I tried several more times without any luck. Afterwards I attempted to start my vehicle and it wouldnt start. No starter cranking but the air, audio, and everything else worked. I called BAMA and then SCT (Which was closed ). BAMA told me to call SCT because I needed a file that would force my vehicle to start and clear the problem out. Well, since they closed at 5:00 PM last night and arent open today I decided to take matters into my own hands. If you come across this issue, please try the fololwing steps to get your car back up and running.

1. Disconnect the positive & negative battery terminal cables.
2. Wait approximately 30 seconds.
3. Touch the negative and positive cables together for 30 seconds. Keep in mind I said the cables, not the terminals on the battery.
4. Reconnect both terminal cables to their respective locations.
5. Start vehicle.

Now you can tune your car again!

Something similar happened to me once, did it lock you out and tell you that all the systems (i.e. charging system, abs, engine etc.) needed to be checked? That's what happened to me. I just let it set for about 30 mins and I was really freaked out because I though I had a 3600 lb grabber blue paper weight, decided to have it towed to dealer next day (happened on a Sunday) but then tried one last time to start it and it sure did

Untamed5.0,

I am sorry to hear about the issue with your device. This is very rare, its usually something in the firmware that just needs to be updated. A quick fix like taking the negative terminal off for a few seconds will do the trick.

I am glad to see that you got it figured out. I would still have SCT send you a firmware update just to update your device with the newest software.

If you have any issues in the future, shoot me a PM & I will make sure you are taken care of!

Bowtiebeater,

You do not have to worry my friend! SCT hand held tuners are very reliable, we ship out thousands a week with absolutely no problem. When shipping out this quantity, there is bound to be a bad egg or some software that needs updating & unfortunately our friend here needs one of those updates.

I assure you, we stand behind all of our products. We will never leave you stranded! If you ever do have an issue, rest easy that we will get you taken care of.

If you have further questions on what we have to offer, Our Bama Performance tuning specialists are here in the building Monday-Friday from 9AM-5:30PM EST and Saturday 10AM-3PM EST. You can hit them up directly at 888.226.9764!

- Dan
