Is the neutralization of Smart Key ECM/PCM, Engine ECM/PCM and key teaching normal ?
 | ▶ 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" procedure. |
 | ▶ 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" procedure. |
■ PIN code is programmed in Smart key ECM/PCM, Tansponder, ESCL.
1. If the Smart key ECM/PCM is not registered with PIN, key teaching process is not proceeded.
2. Registering PIN is available after Smart Key ECM/PCM is neutralized.
3. Neutralization of Engine ECM/PCM is available with GDS (Registering PIN code)
4. If the virgin engine ECM/PCM is installed on vehicle, Engine ECM/PCM is automatically programmed PIN code by Smart Key ECM/PCM.
5. Registering PIN code is only possible for virgin or neutralized status.
■ All Learning procedure is able to do with a GDS in the vehicle's ignition key off state.
Smart Key ECM/PCM Learning
1. Before learning procedure for ESCL, Smart Key ECM/PCM should be registered PIN code first.
2. In case of replacing Smart Key ECM/PCM, All of the keys should be newly registered again.
3. 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.
4. If the battery is discharged during neutralization or Teaching, Timer will start again from begining.
Therefore, it is avoidable to wait for 1 hour.
ESCL Learning
1. It is O.K for registering ESCL just one time. And, it is available for ESCL to neutrailze and re-teach with same PIN code.
