General Description

ECM equipped with Immobilizer function has 4 different Immobilizer S/W(Smartra 2, Smartra 3, PIC and PIC2 START STOP BUTTON SWTICH). With initial IG ON, ECM decides what kind of ECM it is, so call, it is ECM auto-detection.

Immobilizer function is kept its SW Until neutralizing ECM.

DTC Description

ECM sets DTC P1610 if Non START STOP BUTTON SWITCH EMS is installed on vehicle equipped with START STOP BUTTON SWITCH Immobilizer.

Diagnostic Circuit Diagram
Monitor Scantool Data
■ Check DTC
1.

Connect GDS to Data Link Connector(DLC).

2.

Ignition "ON" & engine "OFF".

3.

Select "Diagnostic Trouble Codes(DTCs)"mode.

note

If Non START STOP BUTTON SWITCH immobilizer ECM is installed, Checking Current Data is not available. Because ECM will send Not O.K signal to GDS.

4.

Is the DTC P1610 present ?

▶ Substitute with a known-good ECM with START STOP BUTTON SWITCH immobilizer and check for proper operation.If the problem is corrected, replace ECM and then go to "Verification of Vehicle Repair" procedure.

▶ Fault is intermittent caused by poor contact in ECM's connector or was repaired and 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.

note

■ PIN code is programmed in Smart key ECM, 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 GDS (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 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.

Verification of Vehicle Repair

After a repair, it is essential to verify that the fault has been corrected.

1.

Connect GDS and check "No. of Key learnt, ECM status and Smartkey ECM status

2.

Selet "Diagnostic Trouble Codes(DTCs)" mode and then clear DTC

3.

Operate the vehicle within the enable condition and monitor the DTC on the GDS.

4.

Are any DTCs present ?

▶ Go to the applicable troubleshooting procedure.

▶ System is performing to specification at this time.
