3. Check Smart key status if DTC is retrieved.
4. Is the Smart key PCM/ECM learnt status? YES Fault is intermittent caused by poor contact in Smart key PCM/ECM and/or PCM/ECM's connector or was repaired and Smart key PCM/ECM 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-587144-S25068888332013112200000) " procedure. NO Go to " «COMPONENT INSPECTION»(ref-587144-S42718579792013112200000) " procedure.

Component Inspection

1. Check Smart Key PCM/ECM Inspection

Scheme 217

1. IG KEY "ON" & Engine "OFF".
2. Neutralize smart key PCM/ECM with GDS.
3. Perform key teaching procedure for smart key PCM/ECM with GDS. CAUTION: Pin code must be prepared to Neutralize Smart Key PCM/ECM and to perform key teaching procedure
4. Is the neutralization of Smart Key PCM/ECM, Engine PCM/ECM and key teaching normal? YES Fault is intermittent caused by poor contact in Smart Key PCM/ECM and/or PCM/ECM's connector or was repaired and Smart key PCM/ECM 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-587144-S25068888332013112200000) " procedure. NO Substitute with a known-good Smart Key PCM/ECM and check for proper operation. If the problem is corrected, replace Smart Key PCM/ECM and then go to " «VERIFICATION OF VEHICLE REPAIR»(ref-587144-S25068888332013112200000) " procedure. NOTE: PIN code is programmed in Smart key PCM/ECM, Transponder. If the Smart key PCM/ECM is not registered with PIN, key teaching process is not proceeded. Registering PIN is available after Smart Key PCM/ECM is neutralized. Neutralization of Engine PCM/ECM is available with GDS (Registering PIN code) If the virgin engine PCM/ECM is installed on vehicle, Engine PCM/ECM is automatically programmed PIN code by Smart Key PCM/ECM. 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 PCM/ECM Learning Before learning procedure for Smart Key PCM/ECM should be registered PIN code first. In case of replacing Smart Key PCM/ECM, All of the keys should be newly registered again. In case that Smart Key PCM/ECM 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.

Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness and terminal connections. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found? YES Repair as necessary and go to " «VERIFICATION VEHICLE REPAIR»(ref-587144-S15912838742013112200000) " procedure. NO Go to " «SIGNAL CIRCUIT INSPECTION»(ref-587144-S03208001682013112200000) " procedure.
