Galant L4-2.4L (4G69) (2004)
1. Disconnect powertrain control module connector B-19 and combination meter connector C-101, and measure the resistance at the harness side of
data link connector C-125.
2. Turn the ignition switch to the "LOCK" (OFF) position.
CAUTION: Disconnect the negative battery terminal. For details refer to Service Precautions/Vehicle Damage Warnings.
3. Disconnect the negative battery terminal.
4. Measure the resistance between data link connector terminal 14 and body ground.
OK: 1 kOhm or more
Q: Does the resistance measure 1 kOhm or more?
YES: If the resistance measures 1 kOhm or more, diagnose CAN bus lines thoroughly. Refer to "Diagnostic Item 16".
NO: If the resistance measures less than 1 kOhm, go to Step 30.
