DTC P1697
The PCM and the SMARTRA communicate by dedicated line. During this communication of PCM and SMARTRA the K line of PCM cannot be used for communication. The PCM 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 PCM hard ware.

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

DTC Detecting Condition:

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, PCM and KEY status.




Fig 1 : PCM has not matched with any Key yet.




Fig 2 : PCM Internal Failure.




Fig 3 : IG On with unmatched key.




Fig 4 : 2(two) Keys have been matched with PCM.

4. Is the communication possible between scan tool and Immobilizer system?

YES - If communication between SMARTRA and PCM is OK, Check PCM status of the current data. If PCM 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 other 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, PCM 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.
