PRELIMINARY INFORMATION
Subject:

Delayed Rear Door Power Lock Actuation When Using Passive Remote Entry Function
(Middle East and Korea Only)

Models:

2013 Cadillac CTS Sedan and Wagon with RPO ATH, XL8
Built Prior to March 15, 2013

Condition/Concern
System Design: The Passive Entry Lock Control system is designed so that when the operator approaches a
locked vehicle with the keyless entry transmitter, the remote control door lock receiver will detect the keyless entry
transmitter and when an exterior door handle is pulled, the keyless entry control module will command the door to
unlock and unlatch allowing the door to be pulled open.
Customer Concern: Some customers may comment the rear door locks have a delayed activation when using the
Passive Entry Lock Control system. When pulling on the rear door outside handle, the unlock function may be
delayed for as long as 20 seconds.

Recommendation/Instructions
An updated software calibration has been released to address this condition. Reprogram the Remote Control Door
Lock Receiver (RCDLR) module using the Service Programming System (SPS). This will require contacting your
local technical support center to open a case and obtain a Vehicle Configuration Index (VCI) number.
BEFORE beginning the programming/reprogramming event, please refer to the Programming/Reprogramming
Checklist section in this bulletin.
1. Verify the battery voltage is more than 12 volts but less than 16 volts before proceeding with reprogramming.
(or use programming when needed). The battery must be fully charged BEFORE reprogramming a control
module.
2. During reprogramming, the battery voltage must be maintained within the proper range of 12-15.5 volts.
CONNECT the approved Midtronics ® PSC 550 Battery Maintainer (SPS Programming Support Tool (EL-49642)
to the vehicle or the GR8 (EL50313) in the power supply mode.
⇒ If the above recommended tools are not available, DO NOT connect a battery charger to the vehicle.
CONNECT a fully charged 12V jumper or booster pack that is disconnected from the AC voltage supply.
Notice: It is essential that the TIS terminal, MDI, Tech 2 ® and/or Scan Tool are updated with the latest
software available.
3. Verify that the devices being used are updated with the latest available software version BEFORE beginning
the reprogramming event.
4. BEFORE beginning reprogramming you MUST refer to Control Module References in SI for the appropriate
Programming and Setup procedures.
5. If a wireless connection will be used for reprogramming, a secure service department connection MUST be
used. DO NOT use any public WiFi connection from the customer lounge.
6. Reprogram the RCDLR module using the Service Programming System (SPS) with the latest calibrations
available on TIS2WEB. Refer to the SPS procedures in SI.

Programming/Reprogramming Checklist
•
•
•
•
•

Turn OFF or disable any electrical system, accessory or component that may put an additional electrical load
on the vehicle battery during reprogramming.
Only program a module when you have been instructed to by Service Information (SI), a Bulletin or a Techline
operator.
You MUST refer to Control Module References in SI for the appropriate Programming and Setup procedures.
Thoroughly review the Service Programming System (SPS) in SI BEFORE reprogramming any module.
Some modules will require specific additional programming setup events to be performed BEFORE
reprogramming. Refer to Control Module References for the appropriate Programming and Setup procedures
in SI.

•

Capture and record the Engine Oil Life Remaining information. Record the Engine Oil Life Remaining as a
percentage (%).
• Follow all on-screen instructions in SPS. Verify that the ignition switch is in the proper position.
• If a wireless connection will be used for reprogramming, a secure service department connection MUST be
used. DO NOT use any public WiFi connection from the customer lounge.
• DO NOT run other programs on the computer while reprogramming.
• Use the approved Midtronics® PSC 550 Battery Maintainer (SPS Programming Support Tool EL-49642) or the
GR8 (EL50313) in the power supply mode.
• DO NOT disturb the vehicle, programming device(s) or operate any of its features during reprogramming.
• Some modules will require specific additional programming setup events to be performed AFTER
reprogramming. Refer to Control Module References for the appropriate Programming and Setup procedures
in SI.
• Use a Scan Tool to reset the Engine Oil Life Remaining information to the previous percentage (%) that was
recorded before starting the reprogramming event.
• Verify that all DTCs are cleared after performing the reprogramming event.
• In the event of an interrupted or unsuccessful reprogramming event, document the SPS Error. DO NOT cycle
the ignition. DO NOT replace the ECM. Refer to: PI0592A: Service Programming System (SPS) Errors in SI.
• If further assistance is required call Techline at 1-800-828-6860 (English) or 1-800-503-3222 (French).
