PCM Update With Automatic Transmission Replacement
(Supersedes 03-070, dated July 23, 2003, to update the information marked by asterisks)
REVISION SUMMARY
*Under WARRANTY CLAIM INFORMATION, the flat rate time was changed.*
BACKGROUND
An updated PCM software has been developed that can improve driveability and durability under certain, very specific driving conditions. Although small, there is a possibility that these driving conditions contributed to the transmission's failure. For that reason, the PCM should be updated when installing a remanufactured transmission.
CORRECTIVE ACTION
After installing a remanufactured transmission, update the PCM software.
WARRANTY CLAIMS INFORMATION
The normal warranty applies.
Operation Number: 125517
*Flat Rate Time: 0.3 hour*
Failed Part: P/N 37820-RAA-A54
Defect Code: 091
Contention Code: B02
Skill Level: Repair Technician
REPAIR PROCEDURE
1. Install the remanufactured transmission.
2. If not already done, load the October 2003 or later IN network CD onto the IN master terminal. Loading instructions were included along with the CD's mailing.
3. Make sure the vehicle's battery is fully charged. Low voltage, or turning off the ignition switch, can cause permanent PCM damage.
4. Update the PCM with the HIM (see service bulletin 01-023, Using the Honda Interface Module to Update Control Units/Modules).
5. Connect the Honda Diagnostic System (HDS) to the vehicle's data link connector (DLC). Use the HDS to clear any body electrical codes that may have been set during the PCM update.
6. Cycle the ignition switch to LOCK (0), and then to ON (II). Use the HDS to see if the body electrical codes have returned.
^ If the codes have returned, do the appropriate troubleshooting procedure(s) in the 2003-04 Accord Service Manual, then go to step 7.
^ If the codes are gone, go to step 7.
7. Do the idle learn procedure:
^ Make sure all electrical accessories (A/C, radio, lights, etc.) are off.
^ Start the engine, and let it run until it reaches normal operating temperature (the cooling fans cycle twice).
^ Let the engine idle for 10 minutes.
