A few other people have had similar issues that turned out to be a faulty, or improperly shimmed, crankshaft position sensor.
I googled P0351, and found numerous articles that said that the ECU (not just Ducati) will throw this code when "the ECM detects a problem in the spark timing 1 circuit, it will set DTC P0351." This happens when the ECU detects a problem with the primary coil, not simply a broken circuit, even though that may be the cause. The code is thrown when 80 cycles have occurred without a signal from the primary coil circuit.VDSTS plugged in and it states p0351 "Open Circuit" so it doesn't appear to be the cps. Since I switched the coils, its not that. The only other things are wiring (seems to check out) and lastly the ecu.
Anyone know how to pull a pin from the ecu connector safely? I want to try to bypass the grey/blue with another wire.
I found a really odd problem with my 02 ST4s.Have you tried turning it over in the dark and looking for arcs?
Secondary coil failure and the issue with the lights sounds like a bad ground somewhere.I found a really odd problem with my 02 ST4s.
At high speed, 80mph+, when I'd come up behind a cage on the motorway, if I flashed him with the high beams a few times, it would often drop onto one cylinder. The horizontal cylinder would go. My independent Ducati guy said coils. So I fot a secondhand coil off that eGhay (from a 916) and the problem has never resurfaced.
Strangest bit was, it took me a few goes to work out that it would continue to run on one cylinder until I switched the lights off altogether, then switched 'em back on again, hey presto, from 498cc, back to 996cc!
I may sound like a broken record, and you are free to ignore me, but hear me out.no, it isn't in the cps. The cps is completely separate for the 59m and has its own error code.
In this case the error means that the circuit that goes from the 12v relay power through the brown/white wire to the coil and then back on the grey/blue wire is not making it for some reason, or that the ecu is unable to lift said circuit. You are correct though the lifting breaks the ground and the HV stored in the coil then is transferred to the sparkplug because it is grounded.
so if the brown/white cable is broken somehow, the white/blue cable, the coil, the cable isn't connected properly or the ecu is busted this error should show up. The CPS should not be involved.
