Bulletin No.: PIT5564A Published date: 07/5/2017 Preliminary Information PIT5564A SIR MIL With DTC's B0012 B0013 B0014 B0015 B0019 B0020 B0021 and/or B0022 (Aftermarket USB/Phone Charger) Models Brand: Model: Model Years: VIN: from Engine: to Transmissions: Cadillac Escalade 2007 - 2017 All All All All Chevrolet Avalanche 2007 - 2013 All All All All Chevrolet Silverado 2007 - 2017 All All All All Chevrolet Suburban 2007 - 2017 All All All All Chevrolet Tahoe 2007 - 2017 All All All All GMC Sierra 2007 - 2017 All All All All GMC Yukon 2007 - 2017 All All All All Holden VF/WN 2014 - 2017 All All All All Involved Region or Country North America Some owners may comment of an intermittent SIR MIL. When checking for DTC's, any of the following Condition may be set: B0012, B0013, B0014, B0015, B0019, B0020, B0021, and/or B0022. In most cases, it will have symptom codes for both high and low loop resistance (0D - Loop Resistance Above Threshold and 0E Loop Resistance Below Threshold). This concern could be caused by interference from an aftermarket USB and/or phone charger plugged into the 12 volt power outlet. Below is a screen print of the scan tool displaying the resistance of an air bag deployment loop. - 1 is with only a USB charger plugged into the center console 12 volt power outlet and slight Cause resistance changes can be seen. - 2 is when a phone was plugged into the USB charger and the deployment loop resistance is fluctuating up and down greatly. This fluctuation up and down is why many cases will have both symptoms codes for the loop resistance being above and below threshold (0D and 0E). - 3 is with everything unplugged from the 12 volt power outlet and the resistance is very steady, as it should be. Correction: If, after following normal diagnostics and the root cause is not found, inspect the vehicle and/or question the customer if they are using any type of USB/phone charger/etc. As in the example above, the scan tool was used to monitor the suspect air bag loop resistance while using/operating the aftermarket item plugged into the 12 volt power outlet. If the concern is intermittent and/or can not be duplicated, ask the owner to refrain from using anything that is being plugged into the 12 volt power outlets and see if the issue goes away. Shown below is one example of a USB charger that has caused this type of concern. Version History Version 2 Modified 7/5/17 Updated model years. © 2016 General Motors. All Rights Reserved.
