Service Bulletin2017-07-31. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM:12V/24V/48V BATTERY. Service bulletin - Each replacement high voltage lithium ion battery assembly order includes the loan of a special tool kit that includes the tools required for the battery replacement procedure. The battery and the kit are shipped on a two-level rack, which disassembles into tables to be used as work spaces.

A15-0572017-07-28. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY; ELECTRICAL SYSTEM. Service bulletin - 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.
DLR MSG - RFP -2017-06-21. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY. "DEALER MESSAGE - AMERICAN HONDA (AHM) IS INVESTIGATING CERTAIN 2013-2014 ACCORDS WITH A CUSTOMER COMPLAINT OF CHECK CHARGING SYSTEM MESSAGE DISPLAYED ON MID AS WELL AS HAVING THE DTC B1192 (GAUGE CONTROL MODULE LOST COMMUNICATION WITH BATTERY SENSOR ECU) STORED. TO FULLY UNDERSTAND THE CAUSE OF THIS CONDITION, AHM WOULD LIKE TO COLLECT SPECIFIC PARTS FROM THE VEHICLE IN CERTAIN CONDITION PRIOR TO YOU ATTEMPTING A REPAIR OF ANY KIND."
AER15070A2017-06-21. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY; ENGINE. "ENGINEERING REQUEST - AMERICAN HONDA (AHM) IS INVESTIGATING CERTAIN 2013-2014 ACCORDS WITH A CUSTOMER COMPLAINT OF CHECK CHARGING SYSTEM MESSAGE DISPLAYED ON MID AS WELL AS HAVING THE DTC B1192 (GAUGE CONTROL MODULE LOST COMMUNICATION WITH BATTERY SENSOR ECU) STORED.

PU - A15-0572017-06-19. Service bulletin. ELECTRICAL SYSTEM:12V/24V/48V BATTERY; ELECTRICAL SYSTEM; ENGINE. "SERVICE BULLETIN - 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."
DLR MSG - HONDA2017-06-19. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE; ELECTRICAL SYSTEM:12V/24V/48V BATTERY. "DEALER MESSAGE - TODAY, SEPTEMBER 4, 2015, AMERICAN HONDA IS ANNOUNCING A PRODUCT UPDATE FOR 6,786 ACCORD FHEV VEHICLES TO UPDATE THE HIGH PRESSURE BATTERY CELL MONITORING SYSTEM (CVS). BASIC PROBLEM THE CVS SOFTWARE MAY NOT BE SUFFICIENTLY TOUGH AGAINST ELECTRICAL NOISE FROM THE INVERTER AND MOTOR CIRCUITS. THIS MAY CAUSE THE VEHICLE TO DEFAULT TO A FAIL-SAFE EV-ONLY MODE, REDUCING POWER OUTPUT."
