Any tips for recovering unresponsive roadrunner.

[johnv]

My Roadrunner is unresponsive, happened while loading a tune.
Now won't respond, status unknown, and I get a message that it is not licienced to EFIlive, still displays its serial number and all details are still correct in licience tab.
Any ideas ? won't let me do a hard reset...

I've had a few unexplained glitches with the Roadrunner and EFI Live. All have been cured by disconnecting, closing the Tunetool, reopen and reconnect.

Also look at the USB cable connection, mid cable, not at PC, mine came loose under dash once.

HTH!

Check the soldered connections in the Blue Plug End, one of mine came loose and a quick resolder all was well.

[johnv]

I no longer have the blue plug, have fitted a mini USB to the board.
Can't do anything with it, it acts like a bricked PCM
E-mailed Moates last week but no reply as yet.....

Have heard of peaple removing the internal battery to force a hard reset, any truth to this !!

[mr.prick]

If there is moisture in the case, it will kill the internal battery.
This happened to one of mine.

If the battery is soldered in, the best bet is to send it to Moates for replacement.

[johnv]

Well Pulled it from the car and tried to flash a full tune again today,
just using the USB cable on the Roadrunner and the V2 unplugged and not connected to a bench harness...
And it flashed straight in no problem and reads the loaded tune okay, so all seems to be well again

That should have worked in vehicle too?

There's a procedure for hard reset that I used when I first got my RoadRunner, it did not work, but regular mode did? Wish I knew what this procedure was for?

When you set up a Roadrunner in a vehicle, you will often need to force a ‘hard reset’ of the Roadrunner PCM. This is particularly true if you are using a custom OS or changing OS type.

For using EFI Live, perform the following:
1.Open up the software, and get the EFI Live Roadrunner Control Panel. Make sure the Roadrunner serial number is being displayed.
2.Upload the whole new Operating System and Calibration from the PC *.tun file to the Roadrunner device.
3.Select the “Execute from PCM Flash Memory (if equipped)” option (two chips with arrows in between). This will turn the Roadrunner emulation ‘off’ in order to blank out the PCM RAM when the memory read faults. The software should display ‘Flash’ as the mode of operation.
4.Re-select the button, this time selecting the ‘Emulation’ mode of operation.
5.Turn the key or power to the PCM off, wait 10 seconds, and turn it back on.
6.If you like, at this point you can open the EFI Live ScanTool software (make sure cable is connected and vehicle is on). You will probably want to scan for codes and DTCs, and clear them all as appropriate.
7.Start the vehicle briefly (1-2 seconds) and then shut power back off. This is primarily to reset the idle relearn, so it typically not an issue with the drive-by-wire configurations.
8.You should now be able to restart the PCM and vehicle, and things should work as expected if you are using a valid *.tun file.

This procedure will also help if you have suffered tune corruption.

Anyone know what the above hard reset is for?

[Blacky]

It's purpose is to ensure that all memory in the rr device is initialised correctly. That means, flash memory, battery backed emulation RAM and operational RAM.

[EagleMark]

When I use it vehicle won't start? The other way works?

[joecar]

It sounds like it also clears any learnt things such as trims and idle.

[EagleMark]

When I first got my RoadRunner I used this option and vehicle would not even start. Then using regular method it works like a charm. I tested it again today with vehicle running and used this method and vehicle died?

So I'm still not understanding what it does or when to use it? Seems to just clear/erase the tune...

[EagleMark]

Regards PaulRe-reading your post and the instructions above. Don't clearly understand initialised?

Finally having issues with the RR being non responsive to changes. Connects fine, verifies fine even with wrong file? So something is wrong? One thing that happened before this was turning on and off Lean Cruise Enable during a highway drive for data purposes. It would Enable, but never disable? Since the original note brings up COS, is there an issue with maybe a Cax file parameter as well?

Button options says: "Execute from PCM flash memory if fitted, else execute from RR?" So I tried and it will not flash through V2, looks to be locked?

If vehicle is running and I click this button the vehicle turns off! Click it again and vehicle will start without loading a tun.. So what is it's purpose?

You should never attempt to flash the RR using the V2 - it won't work, its not supposed to work.
The RR should only be programmed using its direct USB connection and the RR Control Panel in the EFILive software.

[mr.prick]

The RR does not operate from PCM flash memory, even if equipped.

I had one without the flash memory option and a hard reset was not possible.
Remove & reinstall of the internal battery was the solution.

Have you contacted Moates?

PaulThen what does that description of button mean? What does it do? Why the write up of it being needed and all mine does is turn vehicle off?

Just trying to understand what it does.

Have you contacted Moates?No, the Roadrunner is working fine, just lost all updates and verify in EFI Live... will enable Lean Cruise but not disable until I turn off vehicle and restart...

So how would you know if you have or not have flash memory option?

[mr.prick]

Switching from emulation to flash kills the engine and it will not run until emulation is reselected.

Moates can tell you from the serial number as well.

[joecar]

Mike, good to see you post :cheers:

(haven't seen you here for a while).

Finally had some time to work on this again. Vehicle has been running OK, no DTCs. But things were just not right? Could enable some things but not disable, then at restart they were off? Some changes were not working or at least not responding like I expected.

Last week I verified tun and it was very quick to say OK...? Usually it takes a few times and a bar scrolls slowly... So I loaded another tun and it still verified...? I knew something was wrong!

So back to today... looked for DTCs and all is well. Read the tun, then compared it to one flashed in and got 2 differences? Dam, I can't find them, I'll have to look in the other PC tomorrow where I saved the corrupt tun, I thought they were D6001 and D6002, when I clicked on them it came up but compare was the same. Something about ROM?

I then read these instructions again, still did not work, just turned engine off! So I tried KOEO! The instructions do not state it has to be done KOEO!!! All the time I had tried with engine running and as soon as I hit the button the engine would die, so I never did get tun loaded.

Been asking here for awhile and even told everyone all it did was turn engine off?

Read these instructions. Do you see anywhere that it needs to be done Key On Engine Off? No. It's an emulator why would I think it needs to be done with engine off?

Well I don't know how long this has been like this but man does the truck run better! All changes now are on/off, and respond instantly and accurately, no more maybes?

Don't know what I found but I think there's a Unresponsive and a dead, maybe mine fell in corrupt tune? Just wish there was a way to tell? Or may just start doing this procedure on a regular basis? I know as soon as I notice any kind of glitch it will be done.

I also have a Moates AutoProm. Although it rarely happens as soon as I notice a glitch of any kind I stop emulation, reload tun (bin), verify and start emulation but never have to turn engine off.

When this started with the Roadrunner I instantly remembered the above instructions, but because they are not complete or accurate as to it must be done KOEO and not KOER it never worked!

Hope that helps someone else! :good:

[joecar]

So step 0 should be KOEO...?

[EagleMark]

Yes! :good:

[Highlander]

I had a roadrunner once that the flash portion worked..... AND you could flash it using efilive (the flash portion not the emulated portion) you could switch on the fly between the 2 and the car wouldn't die......

I don't know why was that eliminated.. sadly... RR died and Moates replaced it... Never again.
