YES | - | Update the ECM if it does not have the latest software, or substitute a known-good ECM, then recheck. If the symptom/indication goes away with a known-good ECM, replace the original ECM. ■
NO | - | Repair open in the wire between DLC terminal No. 7 and ECM connector No. 2 terminal No. 31. After repairing the wire, check for a DTC with the HDS and go to the indicated DTC's troubleshooting.■
