P1696

P1696-EEPROM MEMORY WRITE DENIED/INVALID

For a complete wiring diagram refer to: Electrical Diagrams

When Monitored
Continuously with the ignition on.

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

Possible Causes
- PCM

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding.

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 per Service Information.
Perform 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 per Service Information.
Perform 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 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 POWERTRAIN VERIFICATION TEST. Powertrain Verification Test
