Condition

Some customers may comment on a Malfunction Indicator Lamp (MIL) illuminated and
the Driver Information Center (DIC) displays “Propulsion Power is Reduced” and the
battery will not charge above 30% State of Charge (SOC).
These are the remedial actions taken by the vehicle after diagnostic P0BBD fails.
Scan for DTCs and determine if P0BBD is present. If not, this bulletin does not apply.

Cause

There are some customer driving scenarios which may induce P0BBD without a true
battery cell problem.
Known cases occur at very low vehicles speeds and perhaps by applying the brake and
accelerator at the same time.
Other cases have been found to set during DC Fast Charging on certain models of
chargers.

Correction

Product Engineering has developed a programming solution for the customer driving
scenarios and the charging scenarios.
Important: Not all instances of P0BBD will be induced by the customer or charger, some
may require replacement of the battery pack.

Service Procedure
Important: Service agents must comply with all
International, Federal, State, Provincial, and/or
Local laws applicable to the activities it performs
under this bulletin, including but not limited to
handling, deploying, preparing, classifying,
packaging, marking, labeling, and shipping
dangerous goods. In the event of a conflict between
the procedures set forth in this bulletin and the
laws that apply to your dealership, you must follow
those applicable laws.
1. Using the Investigate Vehicle History screen in GM
Global Warranty Management system, determine if
the field action N212343881, N212343882,
N212345941, or N212345943 are applicable and
CLOSED for the vehicle being repaired.

Copyright 2024 General Motors LLC. All Rights Reserved.

• If field action N212343881, N212343882,
N212345941, or N212345943 are closed for the
vehicle being repaired, program the HPCM2.
Refer to K114B Hybrid/EV Powertrain Control
Module 2: Programming and Setup in SI.
Important: If a Service Programming System (SPS)
message indicating the same software and calibrations
are already present in the HPCM2, you must repair
and/or replace the battery pack. Refer to DTC P0BBD
procedure in service information (SI).
• The February 7, 2024 revision to the HPCM2
software is applicable to all Model Years.
• Any HPCM2 programmed before this date will
need to be programmed again to receive the
updated DC Fast Charge P0BBD solution.
⇒ This update does not affect any other aspect of DC
Fast Charge operation.

Important: N212345941, N212345943, N212343881
or N212343882 must be closed or the programming fix
will not take effect. SPS will check to see whether a
recalled battery has been replaced.
2. If N212343881, N212345941, N212345943 or
N212343882 is open/incomplete, perform that field
action to replace the battery.
Caution: Before downloading the update files, be sure
the computer is connected to the internet through a
network cable (hardwired). DO NOT DOWNLOAD or
install the files wirelessly. If there is an interruption
during programming, programming failure or control
module damage may occur.
• Ensure the programming tool is equipped with the
latest software and is securely connected to the
data link connector. If there is an interruption
during programming, programming failure or
control module damage may occur.
• Stable battery voltage is critical during
programming. Any fluctuation, spiking, over
voltage or loss of voltage will interrupt
programming. Install a GM Authorized
Programming Support Tool to maintain system
voltage. Refer to www.gmdesolutions.com for
further information. If not available, connect a fully
charged 12V jumper or booster pack disconnected
from the AC voltage supply. DO NOT connect a
battery charger.
• Follow the on-screen prompts regarding ignition
power mode, but ensure that anything that drains
excessive power (exterior lights, HVAC blower
motor, etc) is off.
• Please verify that the radio time and date are set
correctly before inserting USB drive into vehicle
for programming, otherwise an error will result.
• Clear DTCs after programming is complete.
Clearing powertrain DTCs will set the Inspection/
Maintenance (I/M) system status indicators to NO.

Bulletin No.: 22-NA-151

Important: The service technician always needs to
verify that the VIN displayed in the TLC left side drop
down menu and the top center window match the VIN
plate of the vehicle to be programmed prior to using
Service Programming System 2 (SPS2) for
programming or reprogramming a module.
• For the TLC application, service technicians need
to always ensure that the power mode (ignition) is
“ON” before reading the VIN from the vehicle’s
VIN master module and that they do not select a
VIN that is already in the TLC application memory
from a previous vehicle.
• If the VIN that shows up in the TLC top center
window after correctly reading the VIN from the
vehicle does not match the VIN plate of the
vehicle, manually type in the VIN characters from
the vehicle VIN plate into the TLC top center
window and use these for programming or
reprogramming the subject module with the
correct vehicle VIN and software and/or
calibrations.
• The Engine Control Module (ECM) is the master
module (for VIP vehicles) that TLC reads to
determine the VIN of the vehicle. If the VIN read
from the vehicle by TLC does not match the VIN
plate of the vehicle, the ECM also needs to be
reprogrammed with the correct VIN, software and
calibrations that match the vehicle’s VIN plate.
• The Body Control Module (BCM) is the master
module (for GEM vehicles) that TLC reads to
determine the VIN of the vehicle. If the VIN read
from the vehicle by TLC does not match the VIN
plate of the vehicle, the BCM also needs to be
reprogrammed with the correct VIN, software and
calibrations that match the vehicle’s VIN plate.

Important: Techline Connect screen shown above.
Important: If the same calibration/software warning is
noted on the TLC Summary screen, select OK and
follow screen instructions. After a successful
programming event, the WCC is located in the Service
Programming System dialogue box of the SPS
Summary screen. Record the WCC on the job card. No
further action is required. Refer to the Warranty
Information section of this bulletin.
1. Program the HPCM2. Refer to K114B Hybrid/EV
Powertrain Control Module 2: Programming and
Setup in SI.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
