Galant L4-2.4L (4G69) (2004)
Q: Does the resistance measure1 kOhm or more?
YES: If the resistance measures 1 kOhm or more, go to Step 16.
NO: If the resistance measures less than 1 kOhm, go to Step 13.
STEP 13. Check A/C-ECU connector C-10 <manual air conditioning system (low)> or C-15 <manual air conditioning system (middle) or
automatic air conditioning system> for loose, corroded or damaged terminals, or terminals pushed back in the connector.
CAUTION: The strand end of the twisted wire should be within 10 cm (4 inches) from the connector. For details refer to Service Precautions/Vehicle
Damage Warnings.
Q: Is A/C-ECU connector C-10 <manual air conditioning system (low)> or C-15 <manual air conditioning system (middle) or automatic air conditioning
system> in good condition?
YES: Go to Step 14.
NO: Repair the damaged parts.
STEP 14. Check the CAN_L and H lines (communication lines only) between joint connector (3) and the A/C-ECU for a short circuit. Measure
the resistance at joint connector (3) C-02.
CAUTION: A digital multimeter should be used. For details refer to Service Precautions/Vehicle Damage Warnings.
CAUTION: The test wiring harness should be used. For details refer to Service Precautions/Vehicle Damage Warnings.
