1. Check for continuity between ECM/PCM connector terminal E16 and body ground.

Is there continuity ?

YES | - | Repair short in the wire between the ECM/PCM (E16) and the EPS control unit.■
NO | - | Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM, then recheck. If the symptom/indication goes away with a known-good ECM/PCM, replace the original ECM / PCM .■
