Chrysler Sebring, Stratus sedan, Sebring Convertible. Manual — part 225
Symptom List:
P1603-PCM INTERNAL DUAL-PORT RAM COMMUNICATION
P1604-PCM INTERNAL DUAL-PORT RAM READ/WRITE INTEG-
RITY FAILURE
P1607-PCM INTERNAL SHUTDOWN TIMER RATIONALITY
Test Note:
All symptoms listed above are diagnosed using the same tests.
The title for the tests will be P1603-PCM INTERNAL DUAL-
PORT RAM COMMUNICATION.
When Monitored and Set Condition:
P1607-PCM INTERNAL SHUTDOWN TIMER RATIONALITY
When Monitored:
During cold start.
Set Condition:
Compares shut down time to coolant temperature.
POSSIBLE CAUSES
FUSED IGNITION SWITCH OUTPUT (OFF-RUN-START)
PCM INTERNAL FAULURE
TEST
ACTION
APPLICABILITY
1
Turn the ignition off.
Disconnect the PCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Turn the ignition to run.
Using a 12-volt test light connected to ground, probe the Fused Ignition Switch
Output (Off-Run-Start) cavity C1-12 circuit at the appropriate terminal of the special
tool #8815.
NOTE: If the test light illuminates, wiggle the wiring harness to ensure that
the problem is not an intermittent wiring problem.
Does the test light illuminate brightly?
All
Yes
→ Replace the Powertrain Control Module in accordance with the
Service Information.
Perform POWERTRAIN VERIFICATION TEST VER - 1.
No
→ Check all related fuses. Repair the Fused Ignition Switch Output
circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 1.

Symptom List:
P1696-EEPROM MEMORY WRITE DENIED/INVALID
P1697-EMR (SRI) MILEAGE NOT STORED
Test Note:
All symptoms listed above are diagnosed using the same tests.
The title for the tests will be P1696-EEPROM MEMORY
WRITE DENIED/INVALID.
When Monitored and Set Condition:
P1696-EEPROM MEMORY WRITE DENIED/INVALID
When Monitored:
Ignition key on continuous.
Set Condition:
An attempt to program/write to the internal EEPROM failed. Also checks
at powerdown.
P1697-EMR (SRI) MILEAGE NOT STORED
When Monitored:
Ignition key on continuous.
Set Condition:
An attempt to program/write to the internal EEPROM failed. Also checks
at powerdown.
POSSIBLE CAUSES
DRB DISPLAYS WRITE FAILURE
DRB DISPLAYS WRITE REFUSED 2ND TIME
DRB DISPLAYS SRI MILEAGE INVALID
COMPARE SRI MILEAGE WITH ODOMETER
TEST
ACTION
APPLICABILITY
1

Does the DRBIII
t display Write Failure?
All
Yes
→ Replace and program the Powertrain Control Module in accor-
dance with the Service Information.
Perform POWERTRAIN VERIFICATION TEST VER - 1.
No
→ Go To 2
2
With the DRBIII
t, perform the SRI Memory Test.
Does the DRBIII
t display Write Refused?
All
Yes
→ Go To 3
No
→ Go To 4

3
With the DRBIII
t, perform the SRI Memory Test a second time.
NOTE: Retest the SRI Memory two more times.
Does the DRBIII
t display Write Refused again?
All
Yes
→ Replace and program the Powertrain Control Module in accor-
dance with the Service Information.
Perform POWERTRAIN VERIFICATION TEST VER - 1.
No
→ Test Complete.
4
With the DRBIII
t, perform the SRI Memory Test.
Does the DRBIII
t display SRI Mileage Invalid?
All
Yes
→ Update the mileage and retest the SRI Memory.
Perform POWERTRAIN VERIFICATION TEST VER - 1.
No
→ Go To 5
5
Compare the SRI Mileage stored with the Instrument Panel Odometer.
Is the mileage within the specified range displayed on the DRBIII
t?
All
Yes
→ Test Complete.
No
→ Update the mileage and retest the SRI Memory.
Perform POWERTRAIN VERIFICATION TEST VER - 1.
