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.

SSM-66637	2016-09-02. Service bulletin. "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 OR 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."
