P1697

GENERAL DESCRIPTION

The ECM and the SMARTRA communicate by dedicated line. During this communication of ECM and SMARTRA the K line of ECM cannot be used for communication. The ECM controls the communication either to SMARTRA or to other devices(e.g. scanner) on K line by switching of a multiplexer and specific communication procedures. The multiplexer is a part of ECM hard ware.

DTC DESCRIPTION

This DTC indicates that ECM received invalid tester message / unexpected requests from tester or ECM Locked by timer (e.g. exceeding the maximum limit of twice ignition On or teaching trials).

DTC DETECTING CONDITION





MONITOR SCANTOOL DATA

1. Ignition "ON" & Engine "OFF".
2. Connect Scan tool and clear the DTCs.
3. If the DTCs are retrieved again, monitor "CURRENT DATA" to check No. of Learnt key, ECM and KEY status.
















Fig 1 : ECM has not matched with any Key yet.
Fig 2 : ECM Internal Failure.
Fig 3 : IG On with unmatched key.
Fig 4 : 2(two) Keys have been matched with ECM.
4. Is the communication possible between scan tool and Immobilizer system?
YES
If communication between SMARTRA and ECM is OK, Check ECM status of the current data.
If ECM status is "Lock", Please wait for one hour with IG Key "ON" and then go to " Verification of Vehicle Repair" procedure.

NOTE:
Disconnecting battery or others manipulation can not reduce this time. After connecting the battery the timer starts again for one hour.

NO
Check DLC cable connection between Scanner and DLC. And, update the scan tool program card with latest version. Finally try communication between scan tool and Immobilizer system.
If problem still continues, Substitute with a known-good scan tool and check for proper operation. If the problem is corrected, 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 scan tool and monitor CURRENT DATA to check No. of Learnt key, ECM and KEY status.
2. Select Diagnostic Trouble Codes(DTCs)" mode and Clear the DTCs.
3. Are any DTCs present?
YES
Go to the applicable troubleshooting procedure.
NO
System is performing to specification at this time.
