How to Erase Self-diagnostic Results
1. If the ignition switch stays ON after repair work, be sure to turn ignition switch OFF once. Wait for at least
5 seconds and then turn it ON again.
2. Perform "Diagnostic Procedure Without CONSULT-III" .
3. Turn ignition switch OFF. (The se lf-diagnostic results will be erased.)
11th judgement flicker is longer than others.
Line pressure solenoid valve circuit is short-circuited or discon-
nected.
⇒ Go to AT- 1 3 3
. 12th judgement flicker is longer than others.
CAN communication line is damaged.
⇒ Go to
AT- 8 7
.
Lamp turns off.
Transmission range switch, overdrive control switch, closed throt-
tle position signal or wide open throttle position signal circuit is dis-
connected or TCM is damaged.
(Because overdrive control switch signal, closed throttle position
signal and wide open throttle position signal are input via CAN
communication line malfunction may continue after self-diagno-
sis.)
⇒ Go to AT- 2 0 4 , "
TCM Self-Diagnosis Does Not Activate" .

U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000005928107
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 communica tion 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 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 LogicINFOID:0000000005928108
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “U1000 CAN COMM CIRCUIT” wit h CONSULT-III or 12th judgement flicker without
CONSULT-III is detected when TCM cannot communicate to other control units.
Possible CauseINFOID:0000000005928109
Harness or connector
(CAN communication line is open or shorted.)
DTC Confirmation ProcedureINFOID:0000000005928110
CAUTION:
If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at
least 10 seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode for “TRANSMISSION” with CONSULT-III.
3. Touch “START”.
4. Wait at least 6 seconds or start engine and wait for at least 6 seconds.
5. If DTC is detected, go to AT-89, "
Diagnosis Procedure".
WITH GST
Follow the procedure “WITH CONSULT-III”.
WITHOUT CONSULT-III
1. Turn ignition switch ON.
2. Wait at least 6 seconds or start engine and wait at least 6 seconds.
3. Perform self-diagnosis. Refer to AT-82, "
Diagnosis Procedure without CONSULT-III".
4. If DTC is detected, go to AT-89, "
Diagnosis Procedure".
