Condition

When replacing any of the dual mode charge cord set components under warranty, you
must return the main cord set assembly and both grid plugs: (1) charge cord body, and
(2) swappable grid plugs.
Note: Dual Level Cord set suppliers have changed. Charge Cord Modules and
adaptors are not interchangeable between suppliers.
Note: It is not required to return the storage bag (if equipped). The new charge
cord set and grid plugs will not come with a new storage bag.
Note: Failure to return all components (minus the storage bag if equipped) may result in
a debit of the warranty claim. Charge cords are not to be replaced due to customer abuse
or failure to comply with charge cord instructions. Many charge cords are returned without any trouble found. Additional information is appreciated on the repair order as to why
the cord set is being replaced, such as the LED light status, which grid plug was being
used, etc.
Example: "Charge Cord Fault Detected" - White off / Flashing Red or "Charge Cord
Internal Fault Present - White off/ White off/ Solid Red, as referenced in the Plug-In
Charging Malfunction per Single Mode (voltage) Charge Cord Status Indicator Key in SI.

Cause

The product quality team requests that the module be returned along with the grid plug
the customer is using to be returned to perform proper root cause analysis on the
returned assembly.

Correction

Refer to SI procedures and other published bulletins to aid in cord set diagnosis for
known customer induced issues prior to replacing the cord set under warranty.
All charge cords are part of the Pre-Repair Authorization process for warranty repairs.
Please refer to Service Bulletin # 18-NA-306 for the pre-repair authorization process.
Note: Replacing a cord set for a customer induced condition may result in a debit of the
warranty claim. Warranty coverage is for manufacturing defects.
Note: The individual components are available to repair customer induced, non-warranty
conditions.

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.

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.
