Component Inspection

Check Smart Key ECM (Integrated in IPM) inspection
1. IG KEY "ON" & Engine "OFF"
2. Neutralize smart key ECM (Integrated in IPM) with scantool.
3. Perform key teaching procedure for smart key ECM (Integrated in IPM) with scantool.

CAUTION:
Pin code must be prepared to Neutralize Smart Key ECM and to perform key teaching procedure.








Fig.1) neutralization
Fig.2) Key Teaching
4. Is the neutralization of Smart Key ECM, Engine ECM and key teaching normal?






NOTE:
PIN code is programmed in Smart key ECM (integrated in IPM), Transponder, ESCL, PDM and FOB.
1. If the Smart key ECM is not registered with PIN, key teaching process is not proceeded
2. Registering PIN is available after Smart Key ECM is neutralized.
3. Neutralization of Engine ECM is available with scantool (Registering PIN code)
4. If the virgin engine ECM is installed on vehicle, Engine ECM is automatically programmed PIN code by Smart Key ECM
5. Registering PIN code is only possible for virgin or neutralized status.
It is possible to access to All of the learning procedure only with scantool. And, FOB key must be inserted in FOB holder in order to proceed learning procedure.
(There is only one menu for registering Smart key on the scantool that makes registering all of the component.In case of replacing each module, New registration should be done with scantool)
IPM Learning
1. Before learning procedure for FOB Key, PDM or ESCL, IPM should be registered PIN code first.
2. In case of replacing IPM, All of the keys should be newly registered again.
3. In case that IPM receives 3 times with wrong PIN, It is not allowed for neutralization and Key Teaching for 1 hour.4. If the battery is discharged while neutralization or Teaching, Timer will start again from begining.
Therefore, it is avoidable to wail for 1 hour.
PDM Learning
1. It is O.K for registering PDM just one time. And, it is available for PDM to neutralize and re-teach with same PIN code.
2. In case that Power supply is shut off to ESCL right before first FOB key is registered, Every component status is moved to right before power shot off and previous PIN is used for communication with PDM and IPM
ESCL Learning
1. 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.
