For the Service Engine Soon light or traction control lamp concern check the X2 connector of the under hood fuse block for poor pin retention.
PIC5804A2017-08-15. Service bulletin. UNKNOWN OR OTHER. This Preliminary Information communication advises the technician of steps to take if Pandora is inoperative or experiencing intermittent operation. 1. Verify Pandora is installed on the device. 2. Make sure the device is Bluetooth connected and paired to Cadillac CUE. 3. Make sure stations have been created in Pandora on the device. 4. Launch Pandora by selecting the Pandora Icon on the Integrated Center Stack and allow a few moments for the App to start on the device. 5. Make sure the Bluetooth volume on the device is turned up or on. Pandora volume is controlled by the device since it is a Bluetooth application. 6. Pandora is controlled by the devices connection and data signal. If the device has a poor data signal Pandora may not play. 7. If Pandora is successfully working, the device should display "Accessory". 8. Apple devices must be connected via USB to the vehicle to launch Pandora. Customers can use the "Bluetooth" input under the media selection to stream audio but will not have full control of the device using the radio. 9. Some Android phones require a setting in Pandora to allow Pandora to access automotive audio. Launch Pandora on the phone, in Pandora select settings in the upper right hand corner of the screen, select "advanced" and make sure "Bluetooth for Automotive" is checked and enabled. 10. If all of the above tips have been verified, and the message "No Internet Connection" is displayed on the Integrated Center Stack screen, CUE is not picking up the devices internet connection. Ensure that the device has adequate battery life and a good data signal. Check to see if Pandora can be heard through the device itself. If Pandora is playing through the handset device, try repairing the device and/or switching to a different audio screen and coming back to Pandora. 11. If Pandora is installed on a phone and a media device is also connected, such as an IPod that is hardwired to the vehicle, there may be confusion.

On 1500 series trucks and all sport utility vehicle with regular production option code IO3 radio the ambient air temperature sensor is hard wired to the engine control module and then the signal goes on high speed local area network to the body control module from there on low speed local area network to the radio. On 1500 series trucks and all sport utility vehicle with regular production option code IO4, IO5, or IO6 the ambient air temperature sensor is hard wired to the engine control module and then the signal goes on high speed local area network to the body control module from there on low speed local area network to the radio then Most 50 Bus to the Human Machine Interface. On 2500/3500 series trucks production option code IO3 radio the ambient air temperature sensor is hard wired to the instrument panel cluster and then the signal goes on low speed local area network to the radio. On 2500/3500 series trucks production option code IO4, IO5, or IO6 radio the ambient air temperature sensor is hard wired to the instrument panel cluster and then the signal goes on low speed local area network to the radio then Most 50 Bus to the Human Machine Interface.
PIT5379A2017-08-15. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. This Preliminary Information communication provides information to the technician about vehicles that may have a content theft alarm sounding for no apparent reason. Technician may use all published Service Information diagnostics and has not found the cause of the unwanted content theft alarm sounding. Technician should use Global Diagnostic System 2 to review the Body Control Module parameters for "Content Theft Deterrent Trigger History". This is a list of triggers that can cause a content theft alarm sounding. Driver door Passenger door, Left rear door, Right rear door, Rear closure, Tonneau Cover, Hood, Ignition Voltage, Intrusion, Inclination, Telematics enhanced service alarm, Battery reconnect detected, Unauthorized Pulse Width Modulated change, Security Indicates Tamper, and Glass Breakage. If the trigger is an Intrusion inspect for items hanging from the rear view mirror, solar powered dancing characters. When the trigger is a Glass breakage inspect the two rear quarter-panel windows and also in the liftgate glass. The quarter panel windows are attached to the body harness with a connector that looks similar to a 9 volt battery connector inspect them to be fully seated in on the glass. When the trigger is Ignition Voltage/Battery reconnect detected during a cold ambient temperature remote vehicle start event technician should call GM General Motors Technical Assistance Center for further assistance.
PIT5076E2017-08-15. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. This Preliminary Information communication advises the technician to insure that global diagnostic service 2 diagnostic packages are up to date prior to learning the steering angle sensor for a diagnostic trouble code C710 symptom code 71 set in the electronic brake control module or the power steering control module.

Check the body control module ground at the G218 location. The front dash insulator mat may be trapped between the ground eyelet and the body stud. Remove the round nut and eyelet and cut the front dash insulator mat away from the ground stud so it no longer interferes with the ground stud and reinstall the eyelet and ground nut.
PIT54042017-08-15. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL; SUSPENSION. This Preliminary Information communication provides information to the technician on the steps to diagnose and repair vehicles that may have a buffeting vibration and/or drone type noise, exhaust tone change, and/or body pressure booming. The concern may be most noticeable while the engine is operating in 4-cylinder Active Fuel Management mode in the 1,100-1,400 RPM range. If the noise is excessive it may excite the roof sheet metal and compound the issue, if this concern is found refer to the latest version of PIT5318. If the concern is qualified to be present during V4 mode operation, but is deemed to be normal by comparing to a like vehicle, then no further repairs should be made, as this is a normal characteristic. If the concern is qualified to be present during V4 mode operation, but is deemed excessive by comparing to a like vehicle then continue with the direction in the Preliminary Information. Vehicles equipped with the 6.2 liter engine and noise cancellation, the noise cancellation may not be working or working incorrectly this can be the cause of the issue. Technician should inspect for aftermarket audio components, objects blocking the microphones or speakers, Diagnostic Trouble Codes B0560, B1277, B127C, or B127D. By the technician pulling the fuse for the amplifier the noise cancellation will be disabled if the noise improves there may be an issue with the noise cancellation system. Technician should inspect the exhaust system also. Exhaust should be checked when it is hot and cold while the vehicle is in neutral, forward and reverse gear. Inspect the exhaust system for loose and/or missing fasteners, heat shields damaged, joints and/or couplings not properly seated, bracket and/or insulator mounting concerns, inadequate clearance to body and/or chassis components, improper alignment, disconnected and/or missing insulators, cracked, dry-rotted, and/or oil-soaked insulators, stretched, twisted, broken, torn, and/or collapsed insulators, and bent, twist
