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:
If “DTC Confirmation Procedure” has been previously performed, alw ays turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, touch “ERASE” on “SELF-DIAG RESU LTS” and then perform the following procedure to con-
firm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
3. Start engine and wait for at least 6 seconds.
4. If DTC is detected, go to CVT-241, " Diagnosis Procedure " .
