Condition

As part of our ongoing quality process e ective as of 11/11/2021, the Drive Motor
Battery is being placed on an approval process through the General Motors
Technical Assistance Center (TAC). The dealership must contact TAC to establish a
case number and authorization to order the battery pack. TAC will then provide
guidance if internal components should be replaced or if the complete pack should
be replaced. U.S.: If a battery pack it is to be replaced, the dealer would then contact
the Battery Service Center (BSC) to order the Drive Motor Battery Pack with an
approved TAC Case number and order ID. Canada: If a battery pack is to be
replaced, TAC will order the Drive Motor Battery Pack through York Electronics in
Oshawa.
New battery approval will be reviewed and authorized by TAC.

Cause

Engineering will be reviewing all cases

NOTE: Please contact the GM Technical Assistance Center (TAC) @ 877-446-8227 (U.S.) or in Canada 1-800-2637740 (English) or 1-800-263-7960 (French) to review case details.
Use SI procedures to determine whether a pack is needed. GM TAC can provide guidance to repair or replace.
Warranty claims will be audited to ensure the minimum number of parts were replaced to repair the vehicle.
Please note the information required at the time of ordering is contained under Parts Information later in this
document. Batteries are on exchange, and new or refurbished material will be provided at or above the capacity
of the battery being removed.
Material will arrive within 72 hours of ordering. For any delays or backorders, please contact the GM Battery
Service Center by calling 1-833-33 GM BSC (1-833-334-6272) for the current status of your order.

Important: United States: To ship the hybrid battery, the Service Department/Technician will need to obtain the
EL-53076 for removing the Coolant from the battery from the GM Special Tool Loan Program. Refer to Service
Bulletin #16-NA-158: U.S. Dealer Special Tool Loan Program for additional information. Obtain the battery pack
tracking number from the GM BSC or TAC before ordering the EL-51865 Battery Pack Support Fixture as there is
only a 5-day rental period before the tool needs to be returned.

Parts Retention and Returns (United States Service Agents ONLY)
All exchanged Li-Ion drive motor batteries are required to be returned for possible refurbishment. If the batteries
are not returned within 30 days, the dealer will be charged back the value of a replacement battery pack. These
charges are substantial.
Important: Li-Ion batteries are hazardous material. GM requires that at least one person be hazmat certi ed per
servicing dealer. Additional resources for hazardous material shipping can be found as part of appendix G in the
latest version of Service Bulletin # 99-00-89-019. A compromised (damaged) battery is hazardous waste and must
be discharged according to SI procedures for damaged packs. All hazardous materials and hazardous waste must
be shipped in accordance with all local, state, and federal laws.
There are two di erent ways the Li-Ion drive motor pack could be returned, normal exchange or WPC special
parts return request.

Normal Exchange (Core) Return
For most pack replacements, contact CCA Logistics at: [email protected] to arrange a pickup. Ship to
the address on the return Bill of Lading included with the service pack.
DO NOT wait for the warranty claim to be processed before returning the failed used drive motor battery. This
exchanged part is GM's material and is not claimed under the warranty labor operation.
Place a copy of the repair order with the pack to be returned. Failure to return a copy of the repair order with the
shipment may result in a debit. Attach the completed return shipping tag to the Drive Motor Battery Pack cocoon.
DO NOT return the battery pack in any container other than the container (cocoon) that the service battery was
delivered in. The removed unit must be returned complete in the original exchange shipping container.

Canadian Failed Battery Returns
All lithium ion batteries and battery sections that are removed from the vehicle need to be returned to the
appropriate core return center. Refer to GM Global Connect for the latest GM Canada Parts Bulletin relating to
procedures for return of EV Batteries or Sections. This can be found under Parts Bulletins & Resources located in
the application section of the Parts Department page.
Canadian Dealers DO NOT return batteries to an Electronic Service Center (ESC) or to the Warranty Parts Center
(WPC).
Note: If the battery or sections are not returned within 30 days of receipt of the exchange component, the entire
transaction will be debited, and the dealer will also be charged the value of a replacement battery.

Recommendations / Instructions
Please have a certi ed High Voltage Technician follow the diagnostic procedures below while contacting GM TAC
1. If DTCs are present and procedure gives direction to remove internal components; stop, capture GDS2 Session
Log stored data, and test drive vehicle with GDS and MDI, and capture a snap shot of the BECM data when
condition occurs. See Latest version of PIP4902 for correct session logs data collection and procedure for
emailing. TAC will request that you e-mail the Session Logs to them. Do not clear codes prior to capturing data
and calling TAC.
U.S. dealers: PIP5632E can also be used to attach the session logs to the TAC case through the DCM portal.
2. If DTCs are not present, refer to "Symptoms - Hybrid Controls " in SI.
3. If any diagnostic procedure gives direction to remove internal components, stop and call TAC, internal
components should not be removed at this time.
4. Upon review of the diagnosis, TAC will establish a case reference number with approval for the dealer to order
Lithium Ion material directly from the GM Battery Service Center (BSC). Canadian dealers the battery will be
ordered for you
5. After verifying that the high voltage systems are disabled, remove battery assembly per SI procedures.
6. Prior to contacting TAC, check with your parts personnel for the parts department hours of operation (including
Saturdays if open) and the name of the parts contact that will be handling the battery pack. This information

along with the battery identi cation number (BIN) and the 4-digit battery capacity number will need to be
supplied to the BSC prior to ordering the battery.
6.1 The battery pack capacity is located in the BECM under hybrid/electric Vehicle battery pack Capacity data
list. We are looking for the Total Energy storage Capacity in AH
6.2 The battery has a battery identi cation tag that is located on the rear of the battery. Locate the tag and record
the 16-digit battery identi cation number (BIN).
Note: The exchange unit will be shipped without coolant. Follow SI procedure for proper coolant and ll
procedures. Low coolant or wrong coolant could result in internal battery damage
After the Battery has been removed from the vehicle (see service manual procedure), and before placement into
the shipping cocoon, prepare the battery for return by performing the following:
1) Install Coolant plugs (2) in coolant lines. Coolant plugs can be removed from the new service battery assembly
and installed in the returned battery. . Note: As part of the battery removal process, all coolant should be drained
from the drive motor battery using the EL-53076.
In order to properly prepare the used battery for shipping and to ensure safe shipment, all of the above steps
must be followed.
Danger: The high voltage (HV) battery must be protected when outside of the vehicle. This is why the battery must
be immediately placed in the original shipping container (cocoon/crate).

Storage Guidelines:
1) Store the Drive Motor Battery at.
2) Store the Drive Motor Battery in an environmentally protected area.
3) Maintain the Drive Motor Battery at room temperature.
4) Protect the Drive Motor Battery from exposure to liquids.
5) Protect the Drive Motor Battery from physical damage.
6) Store the Drive Motor Battery in a limited-access area.
Danger: Failure to follow these guidelines may result in serious injury or death
