SB-10043894-6014 File in Section: Service Bulletin Bulletin No.: Date: PI0701 March, 2012 PRELIMINARY INFORMATION Subject: Windshield Defroster Operation Models: 2010-2011 Chevrolet Equinox (U.S. and Canada) 2010-2011 GMC Terrain (U.S. and Canada) Equipped with HVAC System RPOs C68 or KA1 Condition/Concern Some customers may comment that it is difficult to set the temperature when in defrost mode. This condition may be caused by the existing HVAC control module calibration lacking temperature sensitivity. Recommendation/Instructions An updated software calibration has been released to address this condition. 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 HVAC System Control 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, TAC 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).
