Galant L4-2.4L (4G69) (2004)
CAUTION: Strictly observe the specified wiring harness repair procedure. For details Service Precautions/Vehicle Damage Warnings.
Q: Do all the resistances measure 2 ohms or less?
YES: If all the resistances measure 2 ohms or less, power supply to the powertrain control module may be suspected. Diagnose the engine. Refer
to MFI diagnosis. See: Testing and Inspection/Symptom Related Diagnostic Procedures/Inspection Procedure 2
NO: If either of the resistances measures more than 2 ohms or all the resistances measure more than 2 ohms, replace the ABS-ECU.
STEP 27. Using scan tool MB991958, diagnose the CAN bus line (Disconnect ABS-ECU connector A-02, and check the ABS-ECU system).
1. Disconnect ABS-ECU connector A-02.
2. Turn the ignition switch to the "ON" position.
3. Diagnose CAN bus lines, and check if the MUT-III screen is as shown in the illustration.
4. Turn the ignition switch to the "LOCK" (OFF) position.
5. Check ABS-ECU connector A-02.
Q: Does the MUT-III screen correspond to the illustration?
YES: If the MUT-III screen corresponds to the illustration, go to Step 28 .
NO: If the MUT-III screen does not correspond to the illustration, refer to diagnostics item 9: Check the CAN_L and H lines for a short circuit.
STEP 28. Check the CAN bus lines between intermediate connector C-29 and the ABS-ECU. Measure the resistance between intermediate
connector C-29 and ABS-ECU connector A-02.
