Flash: MIL Illumination - Misfire Diagnostic Trouble Codes (DTC's) P0300, P0301, P0302, P0303, P0304
OVERVIEW:
This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM).
MODELS:
2002 - 2003 (ST) Sebring/Stratus Coupe
NOTE:
This information applies to vehicles equipped with a 2.4L engine (sales code EY7) and manual transaxle built prior to October 1, 2002 (MDH1001XX) or with an automatic transaxle built prior to September 1, 2002 (MDH0901XX).
SYMPTOM/CONDITION:
The Malfunction Indicator Lamp (MIL) may illuminate due to one or more of the DTC's shown. The DTC('s) may be intermittent and provide no symptoms other than MIL Illumination.
DIAGNOSIS:
Using the DRBIII(R) and CH8425 PCMCIA Diagnostic Card check for DTC's. If other DTC's are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If the condition or DTC's listed above are present or can be duplicated, perform the Repair Procedure.

REPAIR PROCEDURE
NOTE:
When first operating a brand new SRT, error messages will occur before PCM/TCM software is loaded into memory ("Download Error Reconnect/Retry" - will be displayed on the screen). Software must be downloaded from TechTOOLS before the SRT will be functional. This error will no longer display after the first download of vehicle software.
TechTOOLS TO SRT SOFTWARE DOWNLOAD PROCEDURE
1. Open the hood, install a battery charger and verify that charging rate provides approximately 13.5 volts.
2. Perform a module scan of the vehicle you are working on to determine the current level Part Number of the PCM/TCM. This part number will be needed at a later point in this procedure to help identify the correct software to download from TechTOOLS. The SRT or DRBIII(R) w/CH8425 PCMCIA card can be used to ID the controller.
3. Log on to DealerCONNECT and navigate to TechTOOLS located within the Service tab.
4. Connect the SRT to a vehicle using the vehicle interface cable (CH8432-2). The SRT receives power from the vehicle through the 16-way data link connector.
NOTE:
As an alternate power source, the Diagnostic and Reprogramming Tool (DART) power supply cable p/n OT237497 can be optionally used to power the SRT with the DRBIII(R)/CoPilot power supply. This option is useful when downloading software and taking the SRT to a remote location for vehicle reprogramming.
5. Connect the SRT to the DealerCONNECT client using the serial interface cable (CH8432-1). The SRT receives vehicle reprogramming files from TechTOOLS through this cable.
6. Use the "Device Options" tab found in TechTOOLS and select Com Port to SRT. Follow any screen prompts to RELAUNCH TechTOOLS as necessary.
7. Identify the vehicle by using the YME (Year/Model/Engine) selection in TechTOOLS.
NOTE:
TechTOOLS cannot automatically read vehicle information (VIN) from these models.
8. Select the "Show Updates" button in TechTOOLS.
9. TechTOOLS will list the part numbers and descriptions of software available for download into the SRT based on the YME you selected.
NOTE:
Software availability will always be referenced by a Service Bulletin.
10. Select the appropriate software (based on Part Number recorded in step 2) for download into the SRT.
11. Select the "Download to SRT" button in the TechTOOLS screen.
12. Follow any prompts seen on TechTOOLS or the SRT screen.
13. When the software download process to the SRT is complete, disconnect the SRT from the DealerCONNECT client.
NOTE:
The process just completed only programs the SRT with vehicle software.
SRT TO VEHICLE REPROGRAMMING PROCEDURES
Once the SRT is loaded with vehicle software, it can be taken to the vehicle(s) that require update based on applicable Service Bulletins.
NOTE:
The software that is loaded into the SRT will stay in memory indefinitely. This provides a means for reprogramming multiple vehicles over a wide time expanse without having to reload vehicle software into the SRT
1. Connect the SRT to the vehicle with the vehicle interface cable (CH8432-2). Connect both (16-way and 12-way) data link connectors to the vehicle. The SRT is powered by the 16-way data link connector and vehicle communication (reprogramming) occurs through the 12-way data link connector.
CAUTION:
Do not disconnect either data link connector until the reprogramming process is completed.
2. The SRT will boot up after connecting it to the vehicle data link connectors.
3. Follow all screen prompts until the reprogramming function is complete.
4. When the reprogramming function is complete, record the new part number for the Authorized Modification label.
5. After the new part number is recorded, turn off the ignition and remove the SRT from the vehicle.
NOTE:
The following step is required by law.
6. Type the necessary information on the "Authorized Modification Label" p/n 04275086AB and attach near the VECI label (Fig. 1).
POLICY:
Reimbursable within the provisions of the warranty.
