YES
The failure is duplicated. Check for loose terminals and poor connections at the EPS control unit connectors. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting or substitute a known-good EPS motor/control unit , then recheck. If the symptom/indication goes away with a known-good EPS motor/control unit, replace the original EPS motor/control unit .
NO
Intermittent failure, the system is OK at this time. Refer to intermittent failures troubleshooting . If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.
