Test at (1) Disconnect front-ECU connector A-08X and measure the resistance available at the relay box side of the connector. (2) Measure the resistance value between terminal 31 and ground. • The resistance should equal 2 ohms or less. Q: Is the measured resistance 2 ohms or less? YES : Go to Step 8. STEP 7. Check the wiring harness between front-ECU Q: Is the wiring harness between front-ECU connector A-08X (terminal 31) and ground in good condition? connector(s) may have loose, corroded or damaged STEP 8.
