Check for short circuit of CAN communication line to
power circuit
1) Measure voltage at following connector terminals with
ignition switch turned ON.
• Between “E23-3” terminal of ECM connector and
vehicle body ground
• Between “E23-18” terminal of ECM connector and
vehicle body ground
Is each voltage 0 – 1 V?
Go to Step 11.
Repair short to power
supply of CAN
communication line
circuit referring to
“Precaution for CAN
Communication
System: in Section 00”.

Vehicle spec check
Is vehicle equipped with A/T?
Go to Step 12.
Go to Step 14.
12
DTC check in TCM (equipped with A/T)

switch turned OFF.
2) Check DTC P1778 in TCM (equipped with A/T).
Is it indicated?
Go to Step 13.
Substitute a known-
good ECM and recheck.
13
ECM circuit check
1) Disconnect connectors from BCM and TCM (equipped
with A/T) with ignition switch turned OFF.
2) Measure resistance at 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
:
?
Substitute a known-
good BCM (included in
junction block
assembly) and recheck.
Substitute a known-
good ECM and recheck.
14
Combination meter operation check
1) Check combination meter operation for seat belt warning
lamp by fastening and unfastening driver side seat belt
with ignition switch turned ON.
Is check result satisfactory?
Go to Step 15.
Substitute a known-
good BCM (included in
junction block
assembly) and recheck.
15
BCM circuit check
1) Disconnect connectors from combination meter with
ignition switch turned OFF.
2) Connect connectors to BCM.
3) Measure resistance at following connector terminals.
• Between “E46-1” and “G37-2” terminals of BCM
connector
• Between “E46-2” and “G37-2” terminals of BCM
connector
Is resistance below 1
:
?
Substitute a known-
good ECM and recheck.
Substitute a known-
good BCM (included in
junction block
assembly) and recheck.
