YES Fault is intermittent caused by poor contact in Smart key ECM/PCM and/or ECM/PCM's connector or was repaired and Smart key ECM/PCM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to " «VERIFICATION OF VEHICLE REPAIR»(ref-536166-S02271175522013031400000) " procedure.

- Check Smart Key ECM/PCM Insepction IG KEY "ON" & Engine "OFF". Neutralize smart key ECM/PCM with GDS. Perform key teaching procedure for smart key ECM/PCM with GDS. CAUTION: Pin code must be prepared to Neutralize Smart Key ECM/PCM and to perform key teaching procedure Is the neutralization of Smart Key ECM/PCM, Engine ECM/PCM and key teaching normal? YES Fault is intermittent caused by poor contact in Smart Key ECM/PCM and/or ECM/PCM's connector or was repaired and Smart key ECM/PCM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.

NO Substitute with a known-good Smart Key ECM/PCM and check for proper operation. If the problem is corrected, replace Smart Key ECM/PCM and then go to " «VERIFICATION OF VEHICLE REPAIR»(ref-536166-S02271175522013031400000) " procedure. NOTE: PIN code is programmed in Smart key ECM/PCM, Transponder, ESCL. If the Smart key ECM/PCM is not registered with PIN, key teaching process is not proceeded. Registering PIN is available after Smart Key ECM/PCM is neutralized. Neutralization of Engine ECM/PCM is available with GDS (Registering PIN code) If the virgin engine ECM/PCM is installed on vehicle, Engine ECM/PCM is automatically programmed PIN code by Smart Key ECM/PCM. Registering PIN code is only possible for virgin or neutralized status. All Learning procedure is able to do with a scan tool in the vehicle's ignition key off state. Smart Key ECM/PCM Learning Before learning procedure for ESCL, Smart Key ECM/PCM should be registered PIN code first. In case of replacing Smart Key ECM/PCM, All of the keys should be newly registered again. In case that Smart Key ECM/PCM receives 3 times with wrong PIN, It is not allowed for neutralization and Key Teaching for 1 hour. If the battery is discharged during neutralization or Teaching, Timer will start again from beginning. Therefore, it is avoidable to wait for 1 hour. ESCL Learning It is O.K for registering ESCL just one time. And, it is available for ESCL to neutralize and re-teach with same PIN code.
