Campaign - Temporary Torque Reduction
SERVICE UPDATEBulletin No.: 11093
Date: March 24, 2011
Subject: 11093 - Service Update for Inventory and Customer Vehicles Temporary Torque Reduction - Reprogram Transmission Control Module (TCM) - Expires with Base Warranty
Models:
2011 Cadillac SRX
Equipped with Turbo HFV6 Engine (LAU) and 6-Speed Automatic Transmission (MXE)
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 TCM on certain 2011 model year Cadillac SRX vehicles equipped with a turbo HFV6 engine (LAU) and a 6-speed automatic transmission (MXE). On these vehicles, a drop in engine torque can occur for 4 seconds while trying to accelerate with 30-40% throttle from a stop on slippery surfaces. This new calibration will eliminate this condition.
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 (GMVIS2) 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) and TIS2WEB 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 03/17/11 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 transmission control module. Refer to SI and Service Programming System (SPS) documentation for programming instructions, if required.
1. Connect the MDI to the vehicle. Connect the MDI to programming terminal with a cable (USB or LAN).
2. Select J2534 MDI and Reprogram ECU from the Select Diagnostic Tool and Programming Process screen.
3. Select TCM Transmission Control Module-Programming from the Supported Controllers screen.
4. Follow the on-screen instructions.
3. Clear all DTCs.
