SUBJECT:
PCM REPROGRAMMING FOR DTC P0133
This TSB supercedes TSB-03-13-003, issued February, 2003, which should be discarded. This TSB contains new PCM reprogramming database numbers.
PURPOSE
Due to incorrect parameters in the Powertrain Control Module (PCM) software, the "SERVICE ENGINE SOON" light may come on and set DTC P0133 (oxygen sensor slow response). To eliminate this condition, reprogram the PCM as described in this bulletin.
AFFECTED VEHICLES
2001-2002 Diamante
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 verify 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 shown.
a. Verify whether the ROM ID is the same as the ROM ID listed in the table. 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 N04101 or greater.
c. If the database version is less than N04101, install the latest reflash database. Then go to Step 5.
d. If the database version is N04101 or greater, go to Step 7.
5. Turn the ignition key to OFF and disconnect the MUT-III.
6. Gather the following reprogramming equipment:
- Memory Card 128 MByte Compact Flash MB991853
- Memory Card Adapter PCMCIA MB991939
- VCI unit MB991824
- MUT-III main harness B MB991911 (red)
- "Engine Compartment/Control Module" Labels p/n MSSF-024G-00
7. Transfer the reprogramming data from the laptop to the memory card.
8. Remove the memory card from the laptop and install it in the VCI. Connect the VCI to the vehicle.
YOU MUST DISCONNECT THE MUT-III LAPTOP
9. Select "1 Automatic rpg." 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 or higher than the ROM ID in the table, the PCM has been re programmed for this concern.
^ If it is not, verify that the correct database update is in the MUT-III and was transferred to 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.
The table lists the PCM part numbers, ROM IDs, and corresponding vendor numbers that will display after reprogramming.
a. 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 p/n and ROM IDs are the same as those listed in the table.
10. Using a ball-point pen, enter the appropriate PCM part number, vendor number, ROM ID #, this TSB number (TSB-04-13-009), your dealer code, and the current date on the Engine Compartment/Control Module Label (part no. MSSF-024G-00).
11. 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.
12. Affix the Control Module label to the PCM.
