Galant V6-3.8L (6G75) (2005)
STEP 45. Check the CAN_L line (communication line only) between the SRS-ECU connector and the intermediate connector for a short
circuit. Measure the resistance at intermediate connector C-22.
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.
1. Disconnect intermediate connector C-22 and SRS-ECU connector C-121, and measure the resistance at the male side of intermediate connector
C-22 (at floor wiring harness side).
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 intermediate connector terminal 23 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 by referring to DIAGNOSTIC ITEM 16.
NO: If the resistance measures less than 1 kOhm, repair the wiring harness between intermediate connector C-22 and SRS-ECU connector.
