Yes
No
1
Was “A/T System Check” performed?
Go to Step 2.
Go to “A/T System
Check: ”.
2
Check DTC
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Check DTC in ECM, TCM and BCM.
Is there any DTC(s) (other than DTC P1674, P1675, P1676,
P1678 in ECM, DTC P1774, P1775, P1777, P1778 in TCM
and DTC U1073, U1001, U1100, U1101 in BCM)?
Go to applicable DTC
diag. flow.
Go to Step 3.
3
Check TCM for CAN communication error
1) Check DTC in TCM.
Is there DTC P1774?
Go to “DTC P1774:
Control Module
Communication Bus
Off: ”.
Go to Step 4.
4
Check ECM and TCM connectors
1) Check for proper connection at each ECM and TCM
connector terminals with ignition switch turned OFF.
2) If connections are OK, recheck TCM for DTC with
engine running.
Is there DTC P1777?
Go to Step 5.
Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection: in Section
00”.
5
Check TCM power and ground circuit
1) Check for TCM power and ground circuit referring to
“TCM Power and Ground Circuit Check: ”.
Is it in good condition?
Go to Step 6.
Repair TCM power and/
or ground circuits.
6
Check DTC for ECM
1) Check DTC P1674 in ECM.
Is it indicated?
Go to “DTC P1674:
CAN Communication
(Bus Off Error): in
Section 1A”.
Go to Step 7.
7
Check CAN communication line circuit continuity
1) Disconnect connectors from ECM and TCM with ignition
switch turned OFF.
2) Measure resistance at the following connector terminals.
• Between “C37-13” terminal of ECM connector and
“C34-17” terminal of TCM connector
• Between “C37-12” terminal of ECM connector and
“C34-7” terminal of TCM connector
Is each resistance below 1
:
?
Go to Step 8.
Repair open or high
resistance CAN
communication line
circuit referring to
“Precaution for CAN
Communication
System: in Section 00”.
8
Check CAN communication line circuit insulation
1) Measure resistance between “C34-17” and “C34-7”
terminals of TCM connector.
Is resistance infinity?
Go to Step 9.
Repair insulation of
CAN communication
line circuit referring to
“Precaution for CAN
Communication
System: in Section 00”.
9
Check CAN communication line circuit ground short
1) Measure resistance at the following connector terminals.
• Between “C34-17” terminal of TCM connector and
vehicle body ground
• Between “C34-7” terminal of TCM connector and
vehicle body ground
Is each resistance infinity?
Go to Step 10.
Repair shorted to
ground of CAN
communication line
circuit referring to
“Precaution for CAN
Communication
System: in Section 00”.
