Well I'm back from the TT and now need to sort my 1100s Hypermotard that failed to get me there! While riding along a duel carriageway in Wales after covering about 150 miles it suddenly cut out and ground to a halt. The engine light is on and showing error codes 10.2, 11.2,12.2 and 13.2. These are coils down to earth and injection fault codes. It was fitted with a quick shifter which I removed at the side of the road to see if that was causing the problem, but this made no difference. So my question is, where shall I start looking for the problem?
So I've been fishing about under the tank.There appears to be nothing wrong with the coils, injectors or wiring to them I've found the plug with the 3 yellow wires from the regulator has one connector thats gone a bit green and the cable is overheated. I've yet to manage to get the plug apart to clean the contacts as it stuck together, but it measured a high resistance through it. Could this possibly be the cause of my woes? If this is the cause how do I go about clearing the fault codes or will they clear themselves once I sort the problem?
Try a new pump/injector/coil relay. Cheap part that causes no end of problems. Once sorted the codes will clear.
Do you have links for those relays....while ive not had the issue with mine it'd be nice to keep those kind of spares handy...
This would fit the bill https://www.ebay.co.uk/itm/13418248...gyq9EtCRF2&var=&widget_ver=artemis&media=COPY
Cheers Chris - so there are 3 over the bike for those roles (had the engine out of mine a few years back) but never noticed them?
Eventually found time to have a quick look at my bike ( it's been ridiculously busy here) I cut out the burnt connector and soldered the wires. Fitted new relays, but unfortunately the same fault continues, engine warning lamp and error codes 10.2, 11.2,12.2 and 13.2. Any ideas where to look next?
all you can do now is study all ignition/engine running related items, and start with loom runs and connectors looking for light corrosion, it only takes a small amount to throw up a code and possibly stop the system from progressing to the engine churn sequence due to the tiny current involved. If all else fails then you start to think of corrosion within the dashboard unit and/or the ECU. Does the fuel pump prime? The "injector fault" code on one or both of my 3 bikes was always a red-herring due to poor continuity or low battery charge, and a good charge and check of battery lead connections would eventually extinguish this. Sometimes connector checking and spraying with contact cleaner was necessary.
I've had a similar issue on mine...one of the battery terminals vibrated loose. Everything died and the dash lit up like a Christmas tree. Not helped by the battery sitting on a shelf on the fuel tank with no rubber strap to keep it fixed in place.
Well, I finally found some time to look at my bike. Went through all the connectors, cleaned any that were at all dirty and greased them all. Tested again and still the same. Now the interesting bit. When I fitted the exhaust valve delete pipe, cat delete and induction bell mouths and filters, I had CJS to remap the “racing” ecu that came with the Termi exhausts. I still have the standard ecu. I fitted this ecu and it only comes up with error codes for the missing exhaust valve. So is it the remapped racing ecu that is faulty or will the standard ecu only show the missing exhaust valve and not the coil and injector faults until the engine has run?
It is possible your remapped ECU has faulty coil/injector drivers. Your original ECU can be cloned to your remapped one, or, if you source a secondhand ECU that also can be cloned to. Which version ECU is fitted M3C or IAW5AM?
Well Chris at CJS very kindly took a copy of the map on my faulty ECU and put it on my standard ECU (for free and covered the postage back to me) I've just fitted it and everything seems to be working great . Just need it to stop raining and I can give it a test ride.
