Thread: I've nanocomed my gearbox

Hi Ghand2,
I have previously done exactly the same thing with my nanocom (also had the headlights flashing and the audiable alarm 'bong'ing'.. all very worrying indeed.

What I found were some parameters in the Valeo BCU - settings tab were changed. (all I wanted to do was enable speed lock however other settings had somehow changed and were written to memory when I clicked 'write setting'. each time I subsequently 'read' the Valeo BCU settings I was getting different values for some of the parameters...)

First thing, if you haven't already done so, upgrade your nanocom to v2.04, it apparantly fix's some communication errors (and hopefully the changing parameters I was receiving).

Next, go back into the Valeo BCU 'settings' tab (if using the PC interface) and read the settings. Check closely your transmission type, this will appear in TWO different fields i.e. "TRANSMISSION SUSPENSION" - 'Transmission' should be "AUTO" and

"INSTRUMENT PACK" - 'Transmission' should be "AUTOMATIC"

as stated, mine had changed to manual; changing back to automatic and writing the setting fixed my MS problem. Just check every other setting first before writing else you will end up with all sorts of other problems if like me, your nanocom changed some of these values prior to pressing the write button .

I hope this helps, PM me with your email if you like and I will send you a copy of my settings which you can check against.

I'd like to say how valuable this forum is & thanks to its creators & those who take the time to reply. With out this it was going to be a very expensive trucking execise to a distant dealer for a very simple problem.
When searching this problem on here I was advised these lights should be used as a battery indicator. Voltage tested @ 12.4 & rose to 14.4 quickly when started. The starter motor seemed to crank with plenty of energy. Due to this I tried all other solutions suggested in this thread without finding anything wrong. At wits end, went to town & brought the biggest 4wd battery I could fit in. Turned key & they still flashed. Started & they reset within seconds. What a relief! Thank you all.
I would say plugging the nanocom in with the ignition on was most likley the cause to trip it into limp mode. The battery needs to be near new condition to get a reset back out of it. Have downloaded firmwear 2.04 which is supposed to cure this, Geoff
