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”.

Step Action Yes No
1DTC check
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Turn ON ignition switch and check DTC.
Is there DTC U0073 and/or U0140?Go to applicable DTC
diag. flow.Go to Step 2.
2Electric load signal circuit check
1) Start engine and select “Data List” mode on scan tool.
2) Check electric load signal under following conditions
respectively.

position: OFF
Blower speed selector turned to 3rd position or
more: ON
Blower fan signal (Automatic A/C model)
Blower speed selector OFF or 1st position: OFF
Blower speed selector turned to 3rd position or
more: ON
Radiator fan signal
Engine coolant temperature is lower than 100 °C
(212 °F): OFF
Engine coolant temperature is higher than 100 °C
(212 °F): ON
Electric load signal
Engine running, rear defogger switch, small light or
headlight switch OFF: OFF
Engine running, rear defogger switch, small light or
headlight switch ON: ON
Is check result satisfactory?Electric load signal
circuit is in good
condition.Check defective signal
circuit.

Inspection of HVAC Control Module and Its CircuitS6RW0D7224029
HVAC control module and its circuits can be checked at HVAC control module wiring couplers by measuring voltage.
CAUTION!
HVAC control module can not be checked by itself. It is strictly prohibited to connect voltmeter to
HVAC control module with couplers disconnected from it.

Voltage Check
1) Remove HVAC control module referring to “HVAC Control Module Removal and Installation”.
2) Check voltage at each terminal.
NOTE
As each terminal voltage is affected by the battery voltage, confirm that it is 11 V or more when ignition
switch is ON.
