Affected Vehicles
Condition
Battery testing and charging for vehicles equipped with a Battery Data Manager (BDM - J367).
Technical Background
When the InCharge 940 is used as a battery charger in auto mode, it performs a battery condition test and may prematurely fail the battery if the charging
takes place at the jumper posts in the engine compartment. This is due to the added resistance in the system between the battery and jumper posts. When
the InCharge 940 is used as a battery charger in manual mode, the battery condition test is not performed.
Production Solution
Not applicable.
