Product Update: New Software to Help Prevent IMA Battery Deterioration (Supersedes 10-034, dated February 1, 2011, to revise the information marked by the asterisks)
REVISION SUMMARY
*Under WARRANTY CLAIM INFORMATION, the flat rate time was changed because the MVCI updates control modules more efficiently.*
BACKGROUND
American Honda is announcing a product update to help prevent IMA battery deterioration.
Frequent stop-and-go driving with A/C use, especially during warm weather, can keep the IMA battery in a low state-of-charge (SOC). Over time, this may cause battery deterioration and eventual failure.
CUSTOMER NOTIFICATION
Owners of affected vehicles will be sent a notification of this product update. An example of the customer notification is at the end of this service bulletin.
To verify vehicle eligibility, check for at least one of these items:
^ The customer has a notification letter.
^ The vehicle is shown as eligible on a VIN status inquiry.
In addition, check for a punch mark below the fifth character of the engine compartment VIN. A punch mark in that location means this product update has already been completed.
Some of the vehicles affected by this product update may be in your used vehicle inventory. These vehicles must be updated before they are sold or leased. To see if a vehicle is affected by this campaign, do a VIN status inquiry before selling it or returning it to a service customer.
Should an unrepaired vehicle that was in inventory, or that came in for service after this service bulletin was issued, cause an injury or property damage because of the campaigned item, the dealership will be solely responsible to the damaged party, and will be required to defend and indemnify American Honda for any resulting claims.
CORRECTIVE ACTION
NOTE:
If any system indicator lights indicate a problem when the vehicle arrives, troubleshoot and repair as necessary before doing this product update.
Update the PGM-FI software and the IMA battery software with the HDS. Then, if needed, update the A/T (CVT) software.
NOTE:
This software update is needed even if the vehicle was repaired using Service Bulletin 09-058, Low-Charged IMA Battery Causes Low Power When Accelerating As with the previous software update, the new software increases the IMA battery rate of charge, which helps to prevent early battery deterioration.
SOFTWARE INFORMATION
HDS Software Version:
2.022.101 (July 2010) (aqua) or later.
Control Module (CM) Update:
Database Update 02-JUL-2010 or later.
The updated PGM-FI, IMA battery, and A/T (CVT) software program IDs and P/Ns are shown below. If the HDS is loaded with the latest software, and it displays No Update Needed during the update, the software for this service bulletin is already installed.
NOTE:
* ^ When using HDS software version 2.024.007 or later, with a CM update of 19-NOV-10 or later, you must input a three-character code when updating the IMA battery software. For more information and a list of codes, refer to Service Bulletin 10-083, IMA Battery Software and Hardware Updates.*
^ An update may be available for the IMA motor system, but it is not needed for this product update.
WARRANTY CLAIM INFORMATION
NOTE:
This product update ends on July 30, 2013.
After that, any applicable warranty would apply.
Failed Part: P/N 1K100-RMX-A07
Defect Code: 5KC00
Symptom Code: R4200
Skill Level: Repair Technician
REPAIR PROCEDURE
NOTE:
After you do the software update(s), the IMA system will have the following differences. All of them are normal operating characteristics:
^ When at an auto idle stop, the engine restarts sooner. It also now restarts with only two bars displayed on the IMA battery level gauge.
^ Even with up to four bars displayed on the IMA battery level gauge, auto idle stop may not occur.
^ The IMA system reserves battery power to ensure enough power is available to start the vehicle from a stop and for initial acceleration. This reduces the IMA assist as the vehicle speed increases. This change increases the battery's stored energy and overall performance.
^ The IMA battery level gauge more accurately indicates the battery's state-of-charge. Customers will also notice that the level bars stay in the middle of the gauge much longer.
1. Use the HDS to update the PGM-FI software. If needed, also update the IMA battery software and the A/T (CVT) software. For updating information, refer to Service Bulletin 01-023, Updating Control Units/Modules.
NOTE:
Three DTCs may be stored after the software is installed. These DTCs can be erased only after all updates (PGM-FI, A/T (CVT), and IMA battery) are completed. For more information on the three DTCs, refer to Service Bulletin 09-026, 2006-09 Civic Hybrid, 2010 Insight New DTCs U0301, U0302, and U0312.
2. Do the CKP pattern learn procedure with the HDS:
^ In the ADJUSTMENT MENU of the HDS, select CRANK PATTERN.
^ Select CRANK PATTERN LEARNING, and follow the screen prompts.
3. 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 have cycled twice).
^ Let the engine idle for 10 minutes.
4. If you updated the CVT software, select START CLUTCH FEEDBACK LEARN in the HDS, and follow the screen prompts to calibrate the start clutch pressure control.
5. If needed, use the HDS to clear all DTCs from all systems.
6. Center-punch a completion mark below the fifth character of the engine compartment VIN:
^ Slide open the FRAME NUMBER door on the center cowl cover.
^ Use a long punch to reach the VIN.
