P1696-EEPROM MEMORY WRITE DENIED/INVALID

For a complete wiring diagram Consult Diagrams/Electrical.

- When Monitored:
Continuously with the ignition on.

- Set Condition:
An attempt to program/write to the internal EEPROM failed. Also checks at powerdown. One Trip Fault. Three good trips to turn off the MIL.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Initial Inspection and Diagnostic Overview.

Diagnostic Test

1. SCAN TOOL DISPLAYS A WRITE FAILURE
With a scan tool, perform the SRI Memory Test.
Does scan tool display Write Failure?

Yes

- Replace and program the Powertrain Control Module.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test

No

- Go to 2

2. SCAN TOOL DISPLAYS A WRITE REFUSED
With the a scan tool, perform the SRI Memory Test.
Does the scan tool display Write Refused?

Yes

- Go to 3

No

- Go to 4

3. PCM REFUSED 2ND TEST
With a scan tool, perform the SRI Memory Test a third time.

NOTE: Retest the SRI Memory two more times.

Does the scan tool display Write Refused again?

Yes

- Replace and program the Powertrain Control Module.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test

No

- Test Complete.

4. SCAN TOOL DISPLAYS SRI MILEAGE INVALID
With a scan tool, perform the SRI Memory Test.
Does the scan tool display SRI Mileage Invalid?

Yes

- Update the mileage and retest the SRI Memory.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test

No

- Go to 5

5. COMPARE SRI MILEAGE WITH ODOMETER
Compare the SRI Mileage stored with the Instrument Panel Odometer.
Is the mileage within the specified range displayed on the scan tool?

Yes

- Test Complete.

No

- Update the mileage and retest the SRI Memory.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test
