▶ Substitute with a known-good "EMS" and check for proper operation. If the problem is corrected, replace "EMS" and then go to "Verification of Vehicle Repair" procedure.

▶ Substitute with a known-good "EPS ECU" and check for proper operation. If the problem is corrected, replace "EPS ECU" and then go to "Verification of Vehicle Repair" procedure.

▶ Fault is intermittent and caused either by poor contact in connectors or wiring harness, or it has been repaired and EPS ECU memory is not cleared yet. Thoroughly check all connectors (and connections) for looseness, bending, corrosion, contamination, deterioration, and/or damage.

▶ Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.
