Condition

When replacing the dual mode charge cord set under warranty, you must return the main
cordset assembly and the grid plug the customer was using: (1) charge cord body, and
(2) swappable grid plug used by the customer as they are requested by the GM Warranty
Parts Center (WPC). Note: Failure to return both components 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. (It is no longer necessary no return the Grid plug the customer is not
using).

Correction

Refer to SI procedures and other published bulletins to aid in cordset 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.

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.
