Service Bulletin 15-057 September 4, 2015 02271 Version 1 Product Update: HV Cell Voltage Sensor (CVS) Software AFFECTED VEHICLES Year Model 2014–15 Accord Hybrid Trim ALL VIN Range Check the iN VIN statues for eligibility BACKGROUND The cell voltage sensor may incorrectly interpret electrical noise from the inverter and motor circuits as a problem and cause the vehicle to switch to a fail-safe EV mode. Additionally, DTCs P0B3B, high voltage battery cell voltage sensor internal circuit malfunction and P0DA8, motor power inverter module voltage malfunction are often stored. If the vehicle switches to fail-safe EV mode while cruising at highway speed, the engine shuts off and the vehicle will experience a sudden loss of power as the fail-safe EV mode limits vehicle speed to a maximum of about 40 mph. If this occurs, the vehicle may be able to travel for up to 2 miles in fail-safe EV mode, at which time the HV battery will likely fully discharge. In reporting this situation, drivers may say that their vehicle stalled. CUSTOMER NOTIFICATION Owners of affected vehicles will be sent a notification of this campaign. Do an iN VIN status inquiry to make sure the vehicle is shown as eligible. Some vehicles affected by this campaign may be in your new or used inventory. Repair these vehicles before they are sold. CORRECTIVE ACTION Do the inspection and based on your results, update the vehicle or replace the HV battery. SOFTWARE INFORMATION NOTE: Unnecessary or incorrect repairs resulting from a failure to update the HDS or MVCI are not covered under warranty. MVCI Control Module (CM) Update: Application (FW) Version 3.01.42 or later Database Update 04-AUG-2015 or later HDS Software Version: 3.016.042 or later Before beginning the repair, make sure that both the HDS and the MVCI are updated as listed above. Do only the update listed in this service bulletin. Check that the MVCI indicates the applicable program ID listed below (or a later program ID) as the Available Update when the update begins. If the MVCI displays This vehicle does not need an update at this time during the update, the software for this service bulletin is already installed. For more information about updating the HDS, the MVCI, and vehicle systems, refer to Service Bulletin 01-023, Updating Control Units/Modules.

(No DTCs) 0.2 hr 15-057A 5ZF00 JT700 1K410-5K1-A03 1185B1 Do the inspection and update the CVS software. DTC and error codes were set, but they were cleared and the CVS software updated. 0.5 hr 15-057B 5ZF00 JT700 1K410-5K1-A03 1185B2 Do the inspection and the result was to replace the battery. File a separate warranty claim under normal warranty for replacing the HV battery. 0.5 hr 15-057C 5ZF00 JT700 1K410-5K1-A03 Skill Level: Repair Technician INSPECTION AND UPDATE PROCEDURE 1. Connect the HDS and check for DTCs. • • If DTC P0B3B or P0DA8 is not set, go to step 4. If DTC P0B3B and/or P0DA8 is set, do not clear the DTC(s). Save all the freeze data, then go to step 2. 2. Do the HV Battery Diagnosis. Refer to the job aid New Procedures for Servicing the High Voltage Battery. NOTE: The diagnosis displays the HV battery cell voltage failure information for sensor A, sensor B, and sensor C. The errors are 8 digits and appear as a series of 0s and 1s. 3. Check the list for the following failures: • • 00000000 00010000 00010100 If the three sensor failure results include 00010000 along with 00000000 and/or 00010100, write down the failure codes on the RO before clearing all set codes, then go to step 4. If the three sensor failure results do not have 00010000 or have any other codes not listed, write down the failure code(s) on the RO and save the HDS freeze data and the Cell Voltage Sensor Check data, then replace the HV battery. Refer to service information. You will need to file a separate warranty claim under normal warranty for replacing the HV battery. 4. Update the CVS software with the MVCI. Refer to Service Bulletin 01-023, Updating Control Units/Modules. This product update is complete. END Page 2 of 2
