Service bulletin SSM66617

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

"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."
