U0010Medium Speed CAN Communication Bus
- Generic OBD-II code · Network
- How the car detects it
- U0010 is the general fault code for the medium-speed CAN, a slower two-wire network that several makers run next to the fast powertrain bus. Saab/GM documents it as mid-speed GMLAN with (+) and (-) wires and a terminating resistor across them, Ford as MS-CAN; on the F-Super Duty an unplugged connector C408 interrupts it and takes climate control, front control panel and headlamp logic down with it. Code-specific users are Volvo and Mack: their aftertreatment module logs U0010-88 together with U0001-88 when chafed wiring cuts communication, with MIL and possible derate. Ford, by contrast, tells Transit technicians to ignore a U0010 in the rear camera module after BCM programming if the camera works. On passenger cars a fault here mainly costs comfort functions, not driveability.
