Hi guys, the old girls been running a bit rough lately so i downloaded the JPdiag, M3C9 software and hooked it up. I seemed to be getting some inconsistent TPS readings but eventually was happy with that . The APS however was showing 0 no matter what. I removed the APS and the 2 small rubber pipes (without having to dismantle ANYTHING on the bike) and checked everything. I couldn't get any variable resistances and the pipes were all sound ,so i WD'd the plug and reffitted .
The APS now shows D1 . The bike does seem to run smoother ( still pops n bangs on trailing throttle through the Baffless Termis) and still shows D!. Doesnt alter with throttle position. Question: Anybody know what D1 means please. TIA
