P1692

Component Location





General Description

When driver inserts key and IGN "ON", Immobilizer informs status of system and result of Authentication by blinking of immobilizer lamp on instrument cluster. through Authentication procedure immobilizer lamp keep lighting up till engine starts. In normal status. Immobilizer lamp lights up for 30sec Right after ignition "ON". If there's any fault in immobilizer system or in Authentication, lamp blinks 5 times after ignition "ON"

DTC Description

The ECM sets DTC P1692 if there's short circuit in immobilizer lamp circuit.

DTC Detecting Condition





Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness and terminals.
Faults can also be caused by interference from other electrical systems, and mechanical aor chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found?
YES
> Repair as necessary and go to "Verification Vehicle Repair" procedure.
NO
> Go to "W/Harness Inspection" procedure.

Contol Circuit Inspection

Check for open in harness
1. IG KEY OFF
2. Connect SMARTRA connector and disconnect PCM connector
3. IG KEY ON & Engine "OFF"
4. Measure voltage between harness side immobilizer lamp terminal of PCM

Specification : Batt.


5. Is the measured voltage within specifications
YES
> Go to "Component Inspection" procedure
NO
> Check for open or short in harness. Repair as necessary and go to "Verification of Vehicle Repair" procedure.

Visual / Physical Inspection

1. Check immobilizer lamp circuit
(1) Ignition "ON" & Engine "OFF"
(2) Check if immobilizer lamp operates properly.

NOTE:
** Right after ignition "ON", Immobilizer lamp lights up for 30sec.
If lamp blinks 5 times after ignition "ON", there's any fault in immobilizer system.

(3) Is immobilizer lamp operates properly?
YES
> 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
> Go to "Component Inspection" procedure.

Component Inspection

Check immobilizer lamp
1. IG KEY OFF
2. Connect SMARTRA connector and disconnect PCM connector
3. Ground harness side immobilizer lamp terminal of PCM with wire
4. IG KEY ON & Engine "OFF"

Specification : Immobilizer lamp "ON"


5. Is the Immobilizer lamp "ON"?
YES
> Substitute with a known-good ECM and check for proper operation.
If the problem is corrected, replace ECM and then go to "Verification of Vehicle Repair" procedure.

NOTE:
** ECM substitued for old one must be in "Virgin" or "Neutral" status and Pin code is requied to Neutralize ECM and to Register transponder key

NO
> Check that fuse has blown off and harness between ECM connector and Battery is in normal condition. And. 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.

Verification of Vehicle Repair

After a repair, it is essential to verify that the fault has been corrected.
1. Connect scantool and selet "Diagnostic Trouble Codes(DTCs)" mode and then clear DTC.
2. Operate the vehicle and monitor the DTC on the scantool.
3. Are any DTCs present?
YES
> Go to the applicable troubleshooting procedure.
NO
> System is performing to specification at this time.
