"ISSUE: A CUSTOMER MAY REPORT THAT THEIR PHONE, DISCONNECTS DURING OR AFTER PHONE CALLS, SHOWS AS PAIRED BUT NOT AVAILABLE, IS NOT SHOWING AS PAIRED BUT IS AVAILABLE, IS DIFFICULT TO PAIR, AUDIO FRAGMENTS WHEN STREAMING MUSIC AND/OR OTHER UNEXPECTED BEHAVIOR. CAUSE: THIS CAN BE A RESULT OF REDUCED PHONE POWER DUE TO THE FOLLOWING:\- • BATTERY LIFE SOFTWARE UPDATE ON THE CUSTOMERS DEVICE, • OTHER APPLICATIONS RUNNING IN THE BACKGROUND ON THE CUSTOMERS DEVICE \(SUCH AS GAMES, SOCIAL MEDIA APPS, SEARCHING FOR NUMEROUS PAIRED DEVICES\). • A BREAK IN THE LINE OF SIGHT FROM THE IAM TO THE CUSTOMER DEVICE \(E.G. DEVICE IN POCKET CAUSING ATTENUATION BY THE HUMAN BODY\). • ANOMALIES INTRODUCED WITH SOFTWARE UPDATES OF DEVICE THAT MAY REDUCE THE EFFECTIVENESS OF AUTHENTICATION BETWEEN THE CUSTOMER DEVICE AND THE VEHICLE. NOTE: THESE ISSUES ARE WELL DOCUMENTED ON OFFICIAL PHONE MANUFACTURERS “SUPPORT” WEB SITES."

"ISSUE INCORRECTLY CONFIGURED SEAT MODULES CAN CAUSE INCORRECT FUNCTIONING OF THE SEAT, OR BATTERY DRAIN ISSUES.

- [SSM66617](/bulletins/10097364.md), 2017-04-14, Service bulletin: ELECTRICAL SYSTEM:12V/24V/48V BATTERY; ELECTRICAL SYSTEM; EQUIPMENT:ELECTRICAL; ELECTRICAL SYSTEM:PROPULSION SYSTEM:TRACTION BATTERY. "ISSUE: A CUSTOMER MAY REPORT A CONCERN WITH A FLAT BATTERY OR POOR STARTING; WHEN TESTING THE BATTERY IT IS DETERMINED THAT A CHARGE IS REQUIRED. CAUSE: WHEN CHARGING A BATTERY \(BOTH PRIMARY AND SECONDARY\) WITH A BMS \(BATTERY MONITORING SYSTEM\) FITTED, THE EARTH FROM THE CHARGER MUST BE CONNECTED TO A SUITABLE CHASSIS OR ENGINE EARTH \(CHECK TOPIX FOR APPROPRIATE LOCATION\). THIS ALLOWS THE BMS TO SEE THE CURRENT GOING INTO THE BATTERY. HOWEVER WHEN USING A DIAGNOSTIC CHARGER FROM MIDTRONICS SUCH AS GR1, GRX GR8\(110 VOLTS\)THIS CONNECTION PROCESS CAN CAUSE AN INCORRECT BATTERY ANALYSIS DUE TO THE EXTRA RESISTANCE IN THE WIRING WHEN CONNECTED TO A CHASSIS OR ENGINE EARTH."
