Thread: Nanocom Evo

I plugged it into the Puma this arvo and got a fault warning come up!!!! Apparently the EGR valve is stuck. Bugger.
How to unstick (I cleared the fault on the Nano but don't think it can physically unstick anything!) and will it do any damage/cause problems if I leave it til I come back off an trip?
Thank for your advices.
Alan.

@ATH,

Do you still hear the shut down self clean from the EGR valve, sounds like 5 x chukka chukkas? The thing to remember about the nanocom is that it will show both tested and non tested DTC's without differentiating between the two types. If the valve was stuck open the MIL would be lit and the engine would run rough and be quite smokey in the rear end. If it was an untested DTC it would have failed the self test once and be logged as such but after 40 ignition cycles without reoccuring it would be cleared from the logged list. The EGR related P0404 DTC's will appear often mainly because the valve doesn't move quickly enough for the EMS and a not tested DTC is therefore logged. A couple of examples below from my nanocom and Puma.

NANOCOM - PUMAENG.APP - PUMA ENGINE fault file

0404 - 72
Exhaust gas recirculation (EGR) control circuit

actuator stuck open

0404 - 73

They only mentioned it because there had been customer reports of issues with SD cards so they tried a number of them out.

I have just read this myself. Any one considering reflashing their ECU MUST read it.

I was reading that yesterday and was marveling that a thread on powering taken directly from AULRO could have been distilled in to such a ridiculous instruction to always use external power supplies.

At least one member has been told that external powering the nanocom would solve all their problems. Which of course it didn't. It doesn't take much thought to realise that if you have adequate voltage at the battery and all wiring and grounds between obd port and ecu are correct this will not help in the slightest.

It is quite possible to flash an ECU with only a full charged battery. I'd verify you can successfully read the existing map first. If you have trouble doing that, read the nanocom FAQ entry on OBD grounding issues and check the ECU and OBD port grounds.

PM update:

A NNN500030 ECU arrived by courier this afternoon, so I thought I'd put my money on the line: No external CTEK charger operating in power supply mode, no external power supply for the Nanocom. I didn't even put the battery on the charger overnight ( battery is less than 6 months old so I know it's fine).

Ssssscccccaaaaaaarrrrrrrrrryyyyyyyyyyyyy

In reality it was pretty boring. To be on the safe side I read the map file from the ECU and saved to sdcard. Then followed the map upload procedure: Turn the ignition on, turn the ignition off, wait 15 seconds, turn the ignition on again, then wait until you see the "writing map complete". The only thing I would note is don't try to skip the initial "turn the ignition on" or the write will fail. I know, I tried several times If you have the ignition on, turn it off and wait for 15 seconds before turning it on.

Flashing a TD5 ECU with a nanocom can and is indeed be but a walk in the park, as long at the instructions are followed to the letter. But as the results of not doing that can so easily result in very undesirable results we really do have to over emphasise things beyond reason.

I do understand but realistically it might be better to include a voltage check as a part of the instructions rather than a blanket admonition to use external supplies. The Nanocom does have the capability to check system voltages so perhaps it would be reasonable to indicate change over point between "OK", "Iffy - Recharge or use external supply" ranges in regard to battery voltages?

I think the issue is once the process has started, there's no safely stopping without massive issues requiring return to BBS.

It's just a 12v 2w power supply (well thats what I use) that I had laying around left over from some other long demised device.

I can see both sides here, but for the small price to pay for a power supply I think it is good insurance.

I want to get one, so if I just take my Nanocom to Jaycar and ask for a 12v 2w with a plug to fit, this will be ok yes? I assume the small round hole in the side of my N,Com is for power?
