DTC U1010 TRANSMISSION CONTROL MODULE (CAN)
DescriptionINFOID:0000000001703471
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent malfunction detection ability.
Many electronic control units are equipped onto a vehicle, and each control unit shares information and links
with other control units during operation (not independent). In CAN communication, control units are con-
nected with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission
with less wiring. Each control unit transmits/receives data but selectively reads required data only.
On Board Diagnosis LogicINFOID:0000000001703472
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “U1010 CONTROL UNIT(CAN)” with CONSULT-III is detected when TCM cannot
