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