This is special function that engine can be started for moving to an area where the key learning is processed with twice IG ON. This function is only performed in condtion that Engine EMS, Smart key ECM (integrated in IPM), Transponder, PDM and ESCL are all virgin status.
Engine can be started by the sequence.
■ Ignition ON with no cranking , Ignition OFF, Ignition ON with cranking within a time interval
■ The following timing conditions have to be fulfilled for successful start :
- Engine EMS, Smart key ECM (integrated in IPM), Transponder, PDM and ESCL are all virgin status
First Ignition ON more than 0.5 seconds and less than 1.5 seconds.
Ignition OFF time is limited by the minimum of 0.2 seconds and the maximum of 1.5 seconds.
Ignition ON
The number of engine starts by "twice ignition on" is limited. The maximum value is 32 times regardless of cranking.
DTC P1699 is set if twice ignition ON exceeds maximum limit over 32 times.
Item | Detecting Condition | Possible Cause |
Enable Conditions | ● IG ON | ● Exceed the maximum limit of Twice IGN ON |
Detecting time | ● Exceed the maximum limit of Twice IGN ON (Over 32 times) |
IG KEY "ON" & Engine "OFF"
Connect GDS and select immobilizer system (Not PIC or Smart key System)
Only just Check Engine status parameter.
This menu is only for checking the ECM status. Just ignore the Rest of others parameter.(This is only way to check ECM status although selected menu system is different)
Fig 1) It shows that ECU is learnt status(Just ignore rest of others parameter)
Is the ECM status displayed "Lock" ?
 | ▶ Wait for 1 hour until ECM status is unlock with IG ON. After ECM status is unlock, perform the key teaching procedure. Finally, go to 'Verification of Vehicle Repair"procedure. |
 | ▶ Fault is intermittent caused by poor contact in Smart Key ECM and/or ECM's connector or was repaired and Smart key 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" procedure. |
■ PIN code is programmed in Smart key ECM, Transponder, ESCL, PDM and FOB.
If the Smart key ECM is not registered with PIN, key teaching process is not proceeded.
Registering PIN is available after Smart Key ECM is neutralized.
Neutralization of Engine ECM is available with GDS (Registering PIN code)
If the virgin engine ECM is installed on vehicle, Engine ECM is automatically programmed PIN code by Smart Key ECM.
Registering PIN code is only possible for virgin or neutralized status.
■ It is possible to acess to All of the learning procedue only with GDS.
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 GDS that makes registering all of the component. In case of replacing each module, New registration should be done with GDS)
Smart Key ECM Learning
1. Before learning procedure for FOB Key, PDM or ESCL, Smart Key ECM should be registered PIN code first.
2. In case of replacing Smart Key ECM, All of the keys should be newly registered again.
3. In case that Smart Key ECM 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 wail for 1 hour.
PDM Learning
1. It is O.K for registering PDM just one time. And, it is available for PDM to neutrailze 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 shut off and previous PIN is used for communication with PDM and Smart key ECM
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.
After a repair, it is essential to verify that the fault has been corrected.
Connect GDS and check "No. of Key learnt, ECM status and Smartkey ECM status
Selet "Diagnostic Trouble Codes(DTCs)" mode and then clear DTC
Operate the vehicle within the enable condition and monitor the DTC on the GDS.
Are any DTCs present ?
| ▶ Go to the applicable troubleshooting procedure. |
| ▶ System is performing to specification at this time. |
