PCM - Sags/Hesitations/Erroneous DTC #2E
NO: 18-30-98GROUP: Vehicle Performance
DATE: Sep. 4, 1998
SUBJECT:
Sags/Hesitation/Stumble
Or Erroneous DTC $2E
MODELS:
1998 (JA) Stratus/Breeze
NOTE:
THIS INFORMATION APPLIES TO VEHICLES EQUIPPED WITH A 2.0L ENGINE.
SYMPTOM/CONDITION:
1. Sags, hesitation, or stumble after a cold start in ambient temperatures of -7° to 30°C (20° - 86° F). This condition may persist for up to a minute into a drive cycle and is attributed to high driveability index (DI) fuel. See Technical Service Bulletin 14-08-97 for more detail on Driveability Index.
2. Erroneous DTC $2E - EGR SYSTEM FAILURE.
3. Potential I/M (Inspection/Maintenance) emissions failure due to high HO/CO readings.
DIAGNOSIS:
Using the Mopar Diagnostic System (MDS) or the Diagnostic Scan Tool (DRB III(R)) with the appropriate Diagnostic Procedures Manual, verify all engine/transmission systems are functioning as designed. If Diagnostic Trouble Codes (DTC's) are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If DTC $2E is present for no apparent reason or any of the other symptoms have been experienced, perform the Repair Procedure.
NOTE:
WHENEVER A POWERTRAIN CONTROL MODULE (PCM) IS REPLACED DUE TO FAILURE, THE SOFTWARE OF THE REPLACEMENT CONTROLLER SHOULD BE VERIFIED FOR THE LATEST REVISION LEVEL. USE THE FLASH PROCEDURE TO UPDATE REPLACED CONTROLLERS AS NECESSARY.
EQUIPMENT/PARTS REQUIRED:
1 CH6OOO Scan Tool (DRB III(R))
1 CH7035 General Purpose Interface Bus Cable (GPIB)
1 CH7OOO/7001 J1962 Cable
1 04669020 Label - Authorized Software Update
NOTE:
THE MDS AND DRB III(R) ARE REQUIRED TO PERFORM THIS REPAIR AND THE SYSTEM MUST BE OPERATING WITH RELEASE 21 OR HIGHER AND TIL CD RELEASE 1167 OR HIGHER MUST BE INSTALLED.
REPAIR PROCEDURE:
This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software (calibration changes).
1. Connect the MDS (Mopar Diagnostic System) and DRB III(R) (Scan Tool) to the vehicle and power them up.
2. Use the arrow keys and select # 2 MDS DIAGNOSTICS on the DRB III(R) MAIN MENU Screen.
3. Use the arrow keys and select DIAGNOSTIC MENU on the MDS, then press NEXT MENU.
4. Use the arrow keys and select VEHICLE CONTROLLER PROGRAMMING on the MDS, then press NEXT MENU.
5. Use the arrow keys and select PROGRAMMING OF ALL OTHER CONTROLLERS USING MDS & DRB III(R) on the MDS, then press NEXT MENU.
6. Follow the steps presented on the MDS and DRB III(R) which will allow the DRB III(R) to obtain the current part number of the PCM.
7. The MDS will display the part number of the PCM on the vehicle and the appropriate replacement part number, then press NEXT MENU to begin programming.
If the PCM on the vehicle has already been updated or programmed, a NO UPDATES AVAILABLE message will be displayed. Check the part number of the PCM on the vehicle and compare it to the part number displayed. If the PCM has already been updated, then another condition exists that will require further diagnosis and repair.
8. The MDS and DRB III(R) will prompt for any operator action needed during the remainder of the programming process.
NOTE:
THE FOLLOWING STEPS ARE REQUIRED BY LAW.
9. Type the necessary information on the "Authorized Software Update Label" p/n 04669020 (Figure 1). Attach the label to the PCM and cover the label with the clear plastic overlay.
10. Type the necessary information on the "Authorized Modification Label" p/n 04275086 and attach the label near the VECI Label (Figure 2).
11. If the repair was made due to symptom 2, verify the repair by running the EGR MONITOR and checking for 1 trip faults. If 1 trip faults are recorded, further EGR diagnostics will be required.
POLICY: Reimbursable within the provisions of the warranty.
