Troubleshooting
NOTE:
• Before performed trouble shooting, be sure to read the “Precautions of ECM Circuit Inspection: ”.
• When measuring circuit voltage, resistance and/or pulse signal at ECM connector, connect the
special tool to ECM and/or the ECM connectors referring to “Inspection of ECM and Its Circuits: ”.
• Upon completion of inspection and repair work, perform “DTC Confirmation Procedure” and
confirm that the trouble has been corrected.

DTC check
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Check ECM, TCM (equipped with A/T) and BCM for
DTC.
Is there any DTC(s) (other than DTC P1674, P1675, P1676,
P1678 in ECM, DTC P1774, P1775, P1777, P1778 in TCM
(equipped with A/T) and DTC U1073, U1001, U1100, U1101
in BCM)?
Go to applicable DTC
diag. flow.
Go to Step 3.
3
ECM, TCM (equipped with A/T), BCM and combination
meter connectors check
1) Check for proper connection at each ECM, TCM
(equipped with A/T), BCM and combination meter
connector terminals with ignition switch turned OFF.
2) If connections are OK, recheck ECM for DTC with
engine running.
Is there DTC P1674?
Go to Step 4.
Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection: in Section
00”
4
ECM power and ground circuit check
1) Check ECM power and ground circuit referring to “ECM
Power and Ground Circuit Check: ”.
Are they in good condition?
Go to Step 5.
Repair ECM power and/
or ground circuits.
5
DTC check in BCM and TCM (equipped with A/T) (bus
off)
1) Check DTC(s) in TCM (equipped with A/T) and BCM.
Is there DTC(s) P1774 in TCM (equipped with A/T) and/or
U1073 in BCM?
Go to Step 6.
Go to Step 7.
6
DTC check in ECM (bus off)
1) Disconnect connectors from ECM with ignition switch
turned OFF.
2) Check TCM (equipped with A/T) and BCM for DTC(s).
Is there DTC(s) P1774 in TCM (equipped with A/T) and/or
U1073 in BCM?
Go to Step 7.
Substitute a known-
good ECM and recheck.
7
DTC check in ECM
1) Connect connectors to ECM and disconnect connectors
from TCM (equipped with A/T) with ignition switch turned
OFF.
2) Check ECM for DTC.
Is there DTC P1674?
Go to Step 8.
Substitute a known-
good TCM (equipped
