SUBJECT:
PCM REPROGRAMMING FOR
HIGH SPEED MISFIRE (DTC P0300-P0306)
This TSB supercedes TSB-03-13-004, issued February 2003, to include manual transmission models, a new reprogramming database and MUT-III reprogramming procedures.
PURPOSE
Due to incorrect PCM software parameters, the MIL ("SERVICE ENGINE SOON" light) may come on and Diagnostic Trouble Code(s) P0300 through P0306 may set when driving over 70 mph (113 kph) at wide open throttle. Typically, this condition occurs in cold ambient temperatures when the transaxle is shifting from 2nd to 3rd gear. To eliminate this condition, reprogram the PCM as described in this bulletin.
AFFECTED VEHICLES
2003-04 Eclipse GTS and Eclipse Spyder GT and GTS models equipped with V6 variable induction engine (both A/T and M/T)
PROCEDURE
CAUTION
BATTERY VOLTAGE (AS MEASURED AT THE BATTERY POSTS WITHOUT ELECTRICAL LOAD) MUST BE 12.4V OR HIGHER IN ORDER TO REPROGRAM THE PCM.
1. Check the underside of the hood to verity that there is no label previously installed to indicate that this TSB reprogramming has already been done.
2. Verify that the vehicle's PCM part number is listed in the table in Step 10.
a. Verity whether the PCM ROM ID is the same as the ROM ID listed in the table in Step 10. If the ROM ID is the same as or higher than the ROM ID in the table, the PCM has already been reprogrammed for this concern.
3. Use the MUT-III to erase all DTCs set in the PCM.
4. Verify that your MUT-III has the most current version of the reprogramming database:
a. Select "Special Function", then select "ECU Reprogramming."
b. Select "Database File Display". The database version is displayed in the top right corner of the screen. Make sure the database version is N04031 or greater.
c. If the database version is less than N04031, go to Step 5.
d. If the database version is N04031 or greater, go to Step 8.
5. Turn the ignition key to OFF and disconnect the MUT-III.
6. Gather the following reprogramming equipment:
- MUT-III / STV Reflash Update CD 3/04 or later
- Memory Card 128 MByte Compact Flash MB991853
- Memory Card Adapter PCMCIA MB991939
- Engine Compartment/Control Module Labels p/n MSSF-024G-00
7. Install Update CD 3/04 in the MUT-III laptop. Follow the CD installation instructions
8. Transfer the reprogramming data from the laptop to the memory card.
9. Remove the memory card from the laptop and install it in the VCI. Connect the VCI to the vehicle.
10. Reprogram the PCM, using automatic reprogramming. For reprogramming details, refer to TSB-03-00-015.
It will take up to 20 minutes to complete the reprogramming.
NOTE:
If the message ECU at Current Level of VCI appears, the PCM did not reprogram Verify that the ROM ID is the same as the ROM ID listed in the table.
^ If the ROM ID is the same as the ROM ID in the table or higher, the PCM has been reprogrammed for this concern.
^ If it is not, verify that the correct database update is in the MUT-III and was transferred 10 the memory card, and that the memory card is properly installed in the VCI.
CAUTION
DO NOT DISTURB THE HARNESS CABLES OR CONNECTIONS. INTERRUPTION DURING THE PROGRAMMING PROCESS COULD CAUSE THE PCM TO LOSE DATA OR PREVENT FUTURE PCM REPROGRAMMING.
NOTE:
After reprogramming is completed, the new ENG ROM ID and new A/T ROM ID will display alternately with the message "Turn IG SW OFF" every four seconds. Note this information. Verify that the new PCM part number and ROM IDs are the same as those listed in the table.
11. Using a ball-point pen, enter the appropriate PCM part number, vendor number, ROM ID #, this TSB number TSB-04-13-003), your dealer code, and the current date on the Engine Compartment Label (part no. MSSF-024G-00).
12. Carefully remove all dirt and oil from a vacant area near the VECI label on the underside of the hood, and affix the Engine Compartment label.
