Hello all , I am after some assistance with error codes on my 2013 MTS 1200 S , i have had recurring error codes on my bike in recent times , used Melcodiag do read codes please see first batch below. I checked all connections relating to air temp sensor and also the connections to my front abs sensor including the fractured wire issue which is well known. Then reset the codes , went for a ride and for the first 30 minutes no errors at all , then at precisely the same time the check engine light and abs lights returned while riding down hill and braking lightly , please see the image blow of the single error flagged when i rechecked using Melcodiag when i got home . Any assistance would be appreciated , other than this the bike performs faultlessly other than the abs being disabled and an annoying ABS fault error being constantly displayed . Kind regards , Bolt
Cost me about £800 for new abs sensors and had to get codes cleared by dealer as only Ducati can issue the code.
Code C101B Possible Causes Faulty Vacuum Pressure Sensor Vacuum Pressure Sensor harness is open or shorted Vacuum Pressure Sensor circuit poor electrical connection |Code C101B Description The Anti-Lock Brake System (ABS) Module monitors the Vacuum Pressure Sensor. The ABS Module sets the OBDII code when the Vacuum Pressure Sensor is not to factory specifications Maybe some help. Not specific Ducati . Generic fault code.
C error codes are normally associated with wheel rotational speed errors. I have a list of Ducati DTC codes but C101B isn’t listed . However in standard OBDII language C101 is an ABS error. The fact your ABS warning light is on and ABS appears to have been deactivated would seem to confirm this. Forgive me if it seems I’m ‘teaching my grandmother to suck eggs’ but there are 2 sensors, one on the front wheel and one on the back wheel which, via a magnetic pulse effect, measure the rotational speed of each wheel. The readings from the front and rear sensors are continuously monitored by the BBS and/or ECU on the bike. The slightest variation in the signal output from one compared to that from the other will cause the ABS or traction control computers to do their thing. However, if there’s a difference in electrical outputs when there shouldn’t be then it will trigger the fault code. I think you may have a wheel sensor that’s on its way out.
Thank you for assistance all, the speedo is still working fine do based on this the front sensor may be the culprit? Thank you Bolt
