P1696-PCM FAILURE EEPROM WRITE DENIED
For a complete wiring diagramRefer to Section 8W.
When Monitored:
Ignition on and battery voltage greater than 10 volts.
Set Condition:
An attempt to program/write to the internal EEPROM failed, also checks at powerdown.
Possible Causes
SRI MILEAGE INVALID
PCM
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING)
Diagnostic Test
1.SCAN TOOL DISPLAYS WRITE FAILURE
Ignition on, engine not running.
With the scan tool, perform the SRI Memory Test.
Does the scan tool display Write Failure?
Ye s>>
Replace and program the Powertrain Control Module per Service Information.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
No>>
Go To 2
2.SCAN TOOL DISPLAYS WRITE REFUSED
With the scan tool, perform the SRI Memory Test.
Does the scan tool display Write Refused?
Ye s>>
Go To 3
No>>
Go To 4
3.PCM REFUSED 2ND TEST
With the scan tool, perform the SRI Memory Test a second time.
NOTE: Retest the SRI Memory two more times.
Does the scan tool display Write Refused again?
Ye s>>
Replace and program the Powertrain Control Module per Service Information.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
No>>
Te s t C o m p l e t e .
4.SCAN TOOL DISPLAYS SRI MILEAGE INVALID
With the scan tool, perform the SRI Memory Test.
Does the scan tool display SRI Mileage Invalid?
Ye s>>
Update the mileage and retest the SRI Memory.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
No>>
