Galant L4-2.4L (4G69) (2004)
connector. Repair the wiring harness as necessary. The system should communicate with the front-ECU normally.
STEP 5. Check front-ECU connector A-12X for loose, corroded or damaged terminals, or terminals pushed back in the connector.
Q: Is front-ECU connector A-12X in good condition?
YES: Go to Step 6.
NO: Repair or replace the damaged component(s). Refer to Harness Connector Inspection. The system should communicate with the front-ECU
normally.
STEP 6. Check the ground circuit to the front-ECU. Measure the resistance at front-ECU connector A-12X.
1. Disconnect front-ECU connector A-12X and measure the resistance available at the relay box side of the connector.
2. Measure the resistance value between terminal 21 and ground.
-
The resistance should be 2 Ohms or less.
Q: Is the measured resistance 2 Ohms or less?
YES: Go to Step 8.
NO: Go to Step 7.
