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 - Intermittent failure, system is OK at this time. A low battery can cause this problem. Ask the customer if there has been any recent trouble starting the engine.
