DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
WARNING!
• When performing a road test, select a place where there is no traffic or possibility of a traffic
accident and be very careful during testing to avoid occurrence of an accident.
• Road test should be carried out with 2 persons, a driver and a tester, on a level road.

1) Connect scan tool to DLC with ignition switch OFF, if available.
2) Clear DTC in TCM memory.
3) Start engine.
4) Keep engine running at idle speed in “P” range for 10 seconds or more.
5) Check DTC.

DTC U0073: Control Module Communication Bus OffS6RW0D5104051
Refer to “Troubleshooting for CAN-DTC in Section 1A”.
DTC U0100: Lost Communication with ECM / PCM “A”S6RW0D5104052
Refer to “Troubleshooting for CAN-DTC in Section 1A”.
Inspection of TCM and Its CircuitsS6RW0D5104044
TCM and its circuits can be checked at TCM wiring connectors by measuring voltage, pulse signal and resistance.
CAUTION!
TCM cannot be checked by itself, it is strictly prohibited to connect voltmeter or ohmmeter to TCM with
connector disconnected from it.

1) Remove TCM (1) from vehicle referring to “Transmission Control Module (TCM) Removal and Installation”.
2) Connect TCM connectors (2) to TCM.
3) Check voltage and/or pulse signal at each terminal of connectors connected using voltmeter (3) and oscilloscope
(4).
NOTE
• As each terminal voltage is affected by battery voltage, confirm that it is 11 V or more when ignition
switch is ON.
• Voltage with asterisk(*) cannot be measured by voltmeter because it is pulse signal. Check it with
oscilloscope if necessary.
