recommended, it is not required by GM for Service
Management to be involved in a request.

Overview

To download and utilize the App:

The PRA process uses the Certified Service Mobile
Toolbox (CSMT) App to submit an authorization request
prior to replacing any of the components listed above
under warranty. The dealer utilizes the App to submit
details and photos of the condition to GM for review.
Once the request is reviewed, a decision of accepted
(warrantable), rejected (non-warrantable) or rework
(more information required) is returned to the dealer via
device push notification, as well as being
documented in Global Warranty Management (GWM).
The dealer is provided a pre-authorization number for
each request and must include the pre-authorization
number on approved warrantable claims.

1. Search for the CSMT (Certified Service Mobile
Toolbox) within your device’s app store.

Note: The decision is only made on the component
itself (warrantable or non-warrantable). Dealers are still
responsible for claim compliancy as per Service
Policies & Procedures Manual.
The intent of the PRA process is to pre-screen product
concerns while the customer is on the service drive to
determine if the customers’ concern is warrantable.
This provides up-front GM collaboration with the dealer
on warranty/non-warranty decisions. If the determination is not warranty, the dealership has an opportunity to immediately communicate this to the customer
and provide an estimate for the repair.
Pre-Repair Authorization Tool
The Certified Service Mobile Toolbox (CSMT) App is
required to process Pre-Repair Authorization (PRA)
requests covered in this bulletin. Once the App is
downloaded to your mobile device, simply click on the
“PRA” category in the left-hand menu to create and
submit your request.
The CSMT App is free and available for use on select
Android™ and Apple® operating systems including
tablets and iPads. The app can be found and
downloaded from the Google Play™ Store (Android)
and App Store (Apple). Please note that with the large
variety of phones and operating systems, not all
functionalities will appear/operate the same on all
devices.
Current operating system (OS) requirements are as
follows:
Apple (iPhone): iOS versions 15.6 and higher
Android: OS versions 8.1 and higher
If your device is not compatible, check to see if there
are system updates available. Apple and Android
devices unable to update to a compatible system will
no longer be able to access or use the CSMT app.
Users may want to consider upgrading to a compatible
device.
The CSMT App may be used by any member of the
dealer’s service department team as determined
necessary by Service Management. Although it is

This pointed to where the concern was, which makes it easy to view and see the customer’s concern.

5156563

This dealer provided a close-up view of the front and back of the mirror. What is good about these photos is
they are close enough for us to be able to determine if there is any type of impact damage on either side.
Also, the mirrors are clean and the angle the photos are taken does not give a reflection that obstructs the
view of the mirrors.
