Supercede:
The Purpose paragraph in this bulletin has been revised to clarify the condition. Please discard all copies of bulletin 12227, issued September 2012.
This service update includes vehicles in dealer inventory and customer vehicles that return to the dealership for any reason. This bulletin
will expire at the end of the involved vehicle's New Vehicle Limited Warranty period.
Purpose
This bulletin provides a service procedure to reprogram the Keyless Entry Control Module on certain 2013 model year Cadillac ATS and XTS
vehicles. After closing the door, the vehicle will run checks for 2 seconds to determine if the RKE transmitter has been left in the vehicle. During this
two second time window, the outside door handle touchpad will not lock the doors when touched, and the door will not lock. The touchpad will
function normally after the 2 second window. The purpose of this calibration change is to reduce the time that the vehicle will not react to the door
handle touch pad (from approximately 2 seconds to about 1 1/2 seconds).

This service procedure should be completed as soon as possible on involved vehicles currently in dealer inventory and customer vehicles
that return to the dealer for any type of service during the New Vehicle Limited Warranty coverage period.
Vehicles Involved
All involved vehicles are identified by VIN in the Global Warranty Management System - Investigate Vehicle History Application. Dealership
technicians should always check this site to confirm vehicle involvement prior to beginning any required inspections and/or repairs. It is important to
routinely use this tool to verify eligibility because not all similar vehicles may be involved regardless of description or option content.
Additionally, a list of involved vehicles currently in dealer inventory is available on the "Service Update Bulletin Information" link under the
"Service" tab in GM GlobalConnect (US) or attached to the GlobalConnect message (Canada) used to release this bulletin. Customer vehicles that
return for service, for any reason, and are still covered under the vehicle's base warranty should also be checked for vehicle eligibility.
Parts Information
No parts are required for this service update.
Service Procedure
Do not attempt to order the calibration number from GM Customer Care and Aftersales. The calibration numbers required for this service procedure
are programmed into control modules via a Multiple Diagnostic Interface (MDI) with the calibration update. When using a MDI for reprogramming,
ensure that it is updated with the latest software version. Use TIS2WEB on or after 09/26/12 to obtain the calibration. If you cannot access the
calibration, call the Techline Customer Support Center and it will be provided.
For step-by-step programming instructions, please refer to SI and the Techline Information System (TIS) terminal.
1. Verify that there is a battery charge of 12 to 15 volts. The battery must be able to maintain a charge during programming. Only use an
approved Midtronics(R) PSC 550 Battery Maintainer (SPS Programming Support Tool EL-49642) or equivalent to maintain proper battery
voltage during programming.
2. Reprogram the keyless entry control module. Refer to SI and Service Programming System (SPS) documentation for programming
instructions, if required.
1. Connect the MDI to the vehicle.
2. Select J2534 MDI and Reprogram ECU from the Select Diagnostic Tool and Programming Process screen.
3. Select K84 Keyless Entry Control Module -- Programming from the Supported Controllers screen.
4. Follow the on-screen instructions.
3. Clear all diagnostic trouble codes (DTCs).
