Original publication
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

Service
Testing the battery
Follow Guided Fault Finding battery test plan.
Charging the battery
Connect the Midtronics INC-940 diagnostic charging station. Instructions for both Auto Mode and Manual Mode
follow.
AUTO MODE:
1. Connect the InCharge 940 positive cable clamp to the positive battery post.
2. Connect the negative cable clamp to the vehicle’s negative
battery cable downstream at the body attachment point
(Figure 1 and Figure 2).
Tip: This connection ensures J367 remains in the loop
so that it may provide battery charge data to the Gateway
(J533) as the J367 is clamped directly to the battery negative
post.

attachment point (white arrow), shown in an
