DTC U1010 TRANSMISSION CONTROL MODULE (CAN)PFP:31036
DescriptionUCS006KU
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 LogicUCS006KV

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “U1010 CONTROL UNIT(CAN)” with CONSULT-II is detected when TCM cannot
communicate to other control units.
Possible CauseUCS006KW
Harness or connectors
(CAN communication line is open or shorted.)
DTC Confirmation ProcedureUCS006KX
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “TRANSMISSION” with
CONSULT-II.
3. Start engine and wait for at least 6 seconds.
