Dual Battery System Grounding Related to Open 150A Underhood
PDC Fuse Array - MY 2025 RAM 1500 (DT)
Since the launch of the 2025 DT, there have
been a high number of open 150A fuse arrays in
warranty which has proven to be from a lack of

knowledge of how the dual batteries are
interconnected. There are 2 grounds (one from
each battery). See figure below:

From Fig. 1, note that if the ground from only
Point #1 is removed, then the Aux Battery will
still be feeding the system with 12V. The same
is true if only the ground from Point #2 is
removed; the Main battery will then continue to
supply power. This is why it is very important
to properly disconnect the battery grounds
PRIOR to performing any Electrical repairs
because any contact of the battery feed to
ground in the vehicle will most likely blow the
150A fuse in the underhood PDC.

are 300 amps or more which is typically from a
direct short to ground. Note that the maximum
amperage seen on the complete DT system is
only about 200. amps even with low state-ofcharge batteries.

The 150A fuse is designed to only blow around
200% of its rating in order to protect the wiring;
therefore, this fuse will not blow unless there

Below is a picture of an actual DT underhood
showing where the batteries are located in the
vehicle. The service procedure requires that
both grounds be disconnected at the Main and
Aux batteries and protect them from touching
any vehicle metal in order to fully disconnect
any battery power from the entire vehicle prior
to performing Electrical service. (See inside
RED circle)

If the 150A fuse is open during service and the
batteries are fully charged, no issue will appear
immediately. However, if the vehicle is started
and operated for a short time with several
loads turned on and then the vehicle is shut off,

the vehicle may not start again, or the main
battery may be drained enough to set a P2AF5
DTC alerting the technician that the main
battery is low and most likely the 150A fuse is
open.

Reverse Polarity Issue in IDCM, Updated Service Procedure for
Reverse Polarity - MY 2023 - 2024 Alfa Romeo Tonale (GC) / Dodge
Hornet (GG), Jeep Wrangler (JL), Jeep Grand Cherokee (WL), Jeep
Renegade (BV) / Jeep Compass (MV) - All Models and Variants
GENERAL INFORMATION
Please note that in the event of a Reverse
Polarity trigger coming on, this condition may
be due to the following causes:

1. Jump Starting the 12V Battery in the reverse
connection, resulting in reverse polarity
situation.

FCA CARIBBEAN WARRANTY OPERATIONS NEWSLETTER
VOLUME 10, ISSUE 8
The issue will be eliminated with following a
thorough service procedure since this is not a
warrantable issue. Not following the updated
service procedure will result in an IDCM failure,
which will induce and IDCM replacement.
During the Jump-Starting procedure, make sure
the B+ terminal of the battery is connected
correctly to positive clamp, and the GND is
connected to the negative clamp.

Please follow the Jump-Starting Standard
Procedure (JUMP STARTING), present in the
Link-E-Entry system.
Make sure that the Warnings and Caution
statements are read and followed thoroughly.
Please refer to the picture below (Red is
positive, black is negative):

NOTE: No DTCs are triggered as the Reverse Polarity protection is not a requirement in this IDCM.
