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, TCM and BCM connectors
1) Check for proper connection at each ECM, TCM and
BCM connector terminals with ignition switch turned
OFF.
2) If connections are OK, recheck TCM for DTC with
engine running.
Is there DTC P1778?
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 BCM
1) Check DTC U1073 in BCM.
Is it indicated?
Go to “DTC U1073 (No.
1073): Control Module
Communication Bus
Off: in Section 10B”.
Go to Step 7.
7
Check CAN communication line circuit continuity
1) Disconnect connectors from TCM and BCM with ignition
switch turned OFF.
2) Measure resistance at the following connector terminals.
• Between “C34-17” terminal of TCM connector and
“E46-1” terminal of BCM connector
• Between “C34-7” terminal of TCM connector and
“E46-2” terminal of BCM connector
Is each resistance below 1
:
?
Go to Step 9.
Go to Step 8.
8
Check ECM internal circuit
1) Disconnect connectors from BCM with ignition switch
turned OFF.
2) Measure resistance at the following connector terminals.
• Between “E23-3” and “C37-13” terminals of ECM
connector
• Between “E23-18” and “C37-12” terminals of ECM
connector
Is resistance below 1
:
?
Repair open or high
resistance CAN
communication line
circuit referring to
“Precaution for CAN
Communication
System: in Section 00”.
Substitute a known-
good ECM and recheck.
9
Check CAN communication line circuit insulation
1) Disconnect connectors from BCM with ignition switch
turned OFF.
2) Measure resistance at the following connector terminals.
• Between “E23-3” and “E23-18” terminals of ECM
connector
• Between “C37-13” and “C37-12” terminals of ECM
connector
Is resistance infinity?
Go to Step 10.
Repair insulation of
CAN communication
line circuit referring to
“Precaution for CAN
Communication
System: in Section 00”.
