For a complete wiring diagram Refer to Section 8W.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 CausesPCMAlways perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING).1. SCAN TOOL DISPLAYS A WRITE FAILUREWith a scan tool, perform the SRI Memory Test.Does scan tool display Write Failure?YesReplace and program the Powertrain Control Module per Service Information.Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE) NoGo To 22. SCAN TOOL DISPLAYS A WRITE REFUSEDWith the a scan tool, perform the SRI Memory Test.Does the scan tool display Write Refused?YesGo To 3NoGo To 43. PCM REFUSED 2ND TESTWith a scan tool, perform the SRI Memory Test a third time.Retest the SRI Memory two more times.Does the scan tool display Write Refused again?YesReplace and program the Powertrain Control Module per Service Information.Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE) NoTest Complete.4. SCAN TOOL DISPLAYS SRI MILEAGE INVALIDWith a scan tool, perform the SRI Memory Test.Does the scan tool display SRI Mileage Invalid?YesUpdate the mileage and retest the SRI Memory.Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE) NoGo To 55. COMPARE SRI MILEAGE WITH ODOMETERCompare the SRI Mileage stored with the Instrument Panel Odometer.Is the mileage within the specified range displayed on the scan tool?YesTest Complete.NoUpdate the mileage and retest the SRI Memory.Perform the POWERTRAIN VERIFICATION TEST.
