As part of GM’s ongoing quality improvement process, the High
Voltage Drive Motor Battery Pack is currently on restriction
through the GM Technical Assistance Center (TAC). Other internal
battery pack components not containing Lithium-Ion material can
be ordered through CCA without restriction. If a battery section is
required, please refer to the current version of bulletin: 18-NA236
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.

Correction:
PARTS RETENTION AND RETURNS UNITED STATES SERVICE AGENTS Only
All Li-Ion drive motor batteries need to be returned for possible refurbishment. DURING THE
LAUNCH PERIOD THE PRIMARYRETURN METHOD WILL BE THE WPC PROCESS. If the batteries
are not returned within 30 days, the dealer will be charged back the value of a replacement
battery. These charges are substantial. There are two different ways the Li-Ion drive motor
battery or battery section could be returned.
1. Oklahoma City Determination Center: If you do not receive a WPC special request within 3
days of completing the repair contact CCA Logistics CCA Logistics (810-866-9300)
[email protected]. It is expected that the majority of batteries will go
thru this process.
2. Warranty Parts Center (WPC): A Special Parts Return Request will be faxed or e-mailed to
you with proper shipping instructions/location. You must use the BOL that is sent to you.
Do NOT wait for the warranty claim to be processed before returning the failed used
drive motor battery. WPC guidelines below:
Do NOT send a battery back without a Special Parts Return Request.

Prior to calling TAC, please make sure to complete the CT6 Battery Exchange required
Information and diagnosis provided in the recommendations portion of this PI.
Performing the diagnosis and obtaining the required information will minimize the time spent
on the telephone and avoid the need for multiple calls to TAC.
Guidelines for honoring this exchange program are being strictly enforced.
To obtain a replacement drive motor battery, the servicing CT6 hybrid technician must provide
TAC with a detailed customer complaint, conditions, diagnostic trouble codes (DTC.S) and
other useful information as outlined below in the recommendations field.
Danger: Always perform the High Voltage Disabling procedure prior to servicing any High
Voltage component or connection. Personal Protection Equipment (PPE) and proper
procedures must be followed.
The High Voltage Disabling procedure will perform the following tasks:
1) Identify how to disable high voltage.
2) Identify how to test for the presence of high voltage.
3) Identify condition under which high voltage is always present and personal protection
equipment (PPE) and proper procedures must be followed
Before working on any high voltage system, be sure to wear the following Personal
Protection Equipment:
1) Safety glasses with appropriate side shields when within 50 feet of the vehicle, either
indoors or outdoors.
2) Certified and up-to-date Class "0" Insulation gloves rated at 1000V with leather protectors.
3) Visually and functionally inspect the gloves before use.
4) Wear the Insulation gloves at all times when working with the Drive Motor Battery
assembly, whether the system is energized or not.
Failure to follow the procedures exactly as written may result in serious injury or death.

Recommendations / Instructions

Please have a certified CT6 technician follow the diagnostic procedures below prior to
contacting 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 Hybrid Powertrain Control Module 2 (VICM) data when condition occurs. See
Latest version of PIP4902 for correct session logs data collection and procedure for emailing.
TAC may request that you e-mail the Session Logs to them. Do not clear codes prior to
capturing data and calling TAC.
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 and make
arrangements for ordering a part or an exchange battery assembly.
5. 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 identification number (BIN) needs to
be supplied to the TAC consultant prior to ordering the battery.
5.1 The battery has a battery identification tag that is located by the MSD of the battery.
Locate the tag and record the 16 digit battery identification number (BIN). The BIN is the
bottom most number on the label and it starts with a "T" indicator (See Photo Below). If the
battery is not out of the vehicle yet, you can find the BIN by installing the MDI and using GDS
2. Access the Battery Energy Control Module data list and look under the identification
information section and the sixteen digit number will be listed under the parameter: Hybrid/EV
Battery Pack Identification Number.

6. You will have to advise TAC if your dealer has a working fork-lift for loading and unloading
the battery pack assembly.
7. To remove the hybrid battery, you will need to obtain the EL-51865 Battery Pack Support
Fixture. To obtain this lift fixture, you will need to obtain the EL-51865 Battery lift fixture from
the GM loaner tool program. See bulletin: 16-NA-158 for additional information on the
GM loaner tool program.
NOTE: Make sure you get the battery pack tracking number from the Technical Assistance
Center before ordering the EL-51865 Battery Pack Support Fixture as there
is a 5 day rental period before the tool needs to be returned.

8. After verifying that the high voltage systems are disabled, remove battery assembly per SI
procedures.
9. Perform Hybrid Powertrain Control Module 2 (HPCM2) and the Battery Energy Control
Module reprogramming when replacing the new battery pack as well as check and reprogram
all electric propulsion
control modules with the latest calibrations. You will also need to perform a high voltage
DTC clear and a battery pack capacity learn which all can be found under battery replacement
in SI.
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 the Manual Service Disconnect (MSD) Insert. The MSD Insert can be removed from
the new service battery assembly and installed in the returned battery.
Note: The MSD lever should remain with the vehicle and not be returned with the battery
assembly.
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).

Storage Guidelines:
1) Store the Drive Motor Battery flat.
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.
