DTC P1695 EMS MEMORY ERROR

Component Location:

GENERAL DESCRIPTION
This DTC is defined as not only ECM have inconsistent data of EEPROM for number of keys taught, user password state and invalid write operation to EEPROM but ECM can not recognize the unique PIN code during Key Authentication.

DTC DESCRIPTION
This DTC is defined as that ECM, indicator or scantool have some problem.

DTC Detecting Condition:

Schematic Diagram:

MONITOR SCANTOOL DATA
1. Check program for scantool is no problem and the latest version.
2. Ignition "ON" & Engine "OFF".
3. Connect Scan tool and clear the DTCs.




4. If the DTCs are retrieved again, monitor "CURRENT DATA" to check No. of Learnt key, ECM and KEY status.
5. Are both Key and ECM status learnt?

YES
- Fault is intermittent caused by poor contact in the SMARTRA (BCM)'s and/or 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.

NO - Go to "Component Inspection" procedure.

COMPONENT INSPECTION
1. Check ECM
1. Ignition "ON" & Engine "OFF".
2. Perform the Neutral, Teaching, and Password teaching/changing mode.
3. Are both neutral and teaching mode completed?

YES - 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.

NO - 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:
1. Don't forget to prepare for the PIN of the vehicle before removing ECM from the vehicle.
2. Remember that substituting with a known-good ECM should be followed "The things to remember before repair (1)" in "Reference Data in General Information".
(In case of faulty ECM, it has to be replaced with "VIRGIN" or "NEUTRAL" ECM.)

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.
