Fault code 25140 - internal control module error
« on: June 11, 2013, 04:35:22 PM »
This is a fault code that has come up and wondered if it is related to the bike completly cutting out with no lights nothing while riding.

We have replaced the electronic fuel pump and the main relay but this still happens on occasion

Did a search and found that code mentioned several times.
This is one of the good replies:

Hi Jos
Yes I have had this fault code and posted about this approx 16 months ago.

In my case it was on a 2006 R1200RT and what happened was that the brake failure would light up and there was then no servo power to the brakes - so you squeeze harder - then the system rebooted or whatever and full braking power was suddenly applied.  This is positively lethal especially when it happens on one of those twisty mountain passes in Italy.

Cure for me was to remove the multiconnector from the servo unit (the big one on the RHS).  Thoroughly clean all contacts and put together again.  The fault has not returned and this connector gets cleaned annually.  Removing this connector when the ignition is switched on induces this fault code.

And don't ask BMW about this because they couldn't give a stuff.

Hope this helps

2000 F650-GS

Pls see the Forum rules...

especially rules 5 & 6...

post a full AutoScan and we can see what we can do...

best,

hi guys
I agree with Haakom first step clean contacts and clear fault codes take the bike for a ride applying brakes at various strengths and run a auto scan again.

Ahh, ok, you will see that non of the fault codes are currently present... and that an undervoltage fault was logged on the ZFE.. undervoltage has all kinds of issues on ABS... just ask the guys with the older ABS units... and the internal control module error has more detail... Comms start fail... possibly due to low voltage...?

the fault listed in the subject, is in the ABS.. and has nothing to do with the Engine controller.. hence replacement of fuel pump electronics and main relay are of no consequence in this matter...

if the matter is actually the occasional cutting out of the bike.. that has nothing to with the comms start timeout in the ABS...

best,
Stephan

Thanks Stephan - it was just a guess if it may be related

ok, So I take it you're after the occasional cutting out of the bike...

Any chance you can replicate this?  what is really handy is to log the realtime values - naturally best if you could do this continuously so it is already logging once it cuts out... however, if you can not, then second best is to log immediately after the cut-out..

we've had a similar issue once with a BMW tech contacting us and gloating about GS-911... and once we asked him to explain, he told us that they had a 1200RT that had been into the shop with the occasional cutting out... and it's been in and out od the shop 4 or 5 times.. and the customer is not a happy camper.. the tech got his dealership to buy a GS-911, and logged all the test rides he did...

And then on one test ride the bike stalled...  couldn't get it started again...

plotting the data he first found that the injection time was ridiculously long... (remember, normal injection time is 2-5ms and just over 10ms for serious enrichment) - Note how much fuel the ECU is commanding near the end...(of course impossible) see below...


Now remember that this is what the ECU calculated it to be, so there must be a reason the ECU wants to inject this much fuel...  So he looked further.. and found this when looking at the cylinder head temperature sensor value....


now looking at this, you can see that it was a nice summer day in Europe, with in the high 20's (Celsius) and the Cylinderhead Temperature rises to around 90 degC... whereafter it start doing some funnies, until it eventually drops to -40 degC and oscillates between that and operating temperature...

The kicker is of course that this is an intermittent foult on the sensor... thus after it cools down, it works just fine... and every time they test it at the dealership... it works just fine...

Anyway.. the tech replaced the Cylinderhead Temperature Sensor... and the customer has not been back for that stalling problem since...

NOTE: I'm not saying this is your problem... it is however a great example of how GS-911, and especially logging the real-time values, can help to identify a tough intermittent problem...

best,
Stephan

This is impressive. Excellent troubleshooting !!
