DTC U1010 TRANSMISSION
CONTROL MODULE (CAN)
Description INFOID:0000000004305608
CAN (Controller Area Network) is a serial communication li ne for real time application. It is an on-vehicle mul-
tiplex communication line with high data communica tion speed and excellent malfunction detection ability.
Many electronic control units are equipped onto a vehicl e, 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 li ne) allowing a high rate of information transmission
with less wiring. Each control unit transmits/recei ves data but selectively reads required data only.
On Board Diagnosis Logic INFOID:0000000004305609
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “U1010 CONTROL UNIT(CAN)” with CONSULT-III is detected when TCM cannot
communicate to other control units.
Possible Cause INFOID:0000000004305610
Harness or connectors
(CAN communication line is open or shorted.)
DTC Confirmation Procedure INFOID:0000000004305611
NOTE:
