DUAL BATTERY MODULE (DBM)
The DBM (dual battery module) is located at the rear of the right wheel arch in the luggage compartment, adjacent to the
GWM (gateway module) and the RJB (rear junction box). The DBM is attached to a bracket, which is attached to a second
bracket secured to the vehicle body.
The DBM is connected by two hardwired connections to the DBJB (dual battery junction box). The DBM uses these two
connections to apply battery voltage to the contactor coils in the DBJB. A LIN bus connection from the GWM passes contactor operation signals to the DBM which operates the contactors as applicable.
The GWM will also instruct the DBM to apply charging to the secondary battery via a LIN bus message. The GWM instructs the
DBM of the charging current required for the secondary battery and the DBM applies the requested stabilized current to the
secondary battery via a dedicated connection direct to the secondary battery.
The DBM diagnoses the coils of the contactors and will report a fault via the LIN bus to the GWM.
The DBM receives a fused power supply from the RJB. www.JagDocs.com

Diagnosis and Testing
Principles of Operation Published: 10-Mar-2014
For a detailed description of the battery system and operation, refer to the relevant Description and Operation section of the
workshop manual. REFER to: Battery and Cables (414-01 Battery, Mounting and Cables, Description and Operation).
Inspection and Verification
CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not
guarantee confirmation of a fault and may also cause additional faults in the vehicle being checked and/or the donor vehicle.
NOTES:
Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the scan
tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional information
read by the manufacturer-approved diagnostic system).
When performing electrical voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal
places, and with an up-to-date calibration certificate. When testing resistance, always take the resistance of the DMM leads
into account.
Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may be the
cause. Always check for loose connections and corroded terminals.
1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical or electrical damage.

3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to
the next step.
4. If the cause is not visually evident check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.
5. Check DDW for open campaigns. Refer to the corresponding bulletins and SSMs which may be valid for the specific
customer complaint and carry out the recommendations as required
