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 tested and/or the donor vehicle.
1. Verify the customer concern.
2. Visually inspect for obvious signs of damage and system integrity.

NOTE: Particular attention should be paid to the following items where DTCs may not be logged:

Check for contamination (e.g. dirt, grime, frosting, ice) around the blindspot monitoring sensors and clear.

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 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.


Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.


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.


When carrying out repair/diagnosis of the system, on removal of the front or rear bumper inspect the sensor connectors
to ensure they were correctly latched and check fly leads for signs of chaffing or trapped wires.


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

6 Instrument Cluster 7 Rear Junction Box (RJB) CONTROL DIAGRAM - DUAL BATTERY SYSTEM VEHICLES



Item Description 1 Battery Monitoring System (BMS) control module 2 Tandem Solenoid Starter (TSS) motor 3 Generator 4 Engine Junction Box (EJB) 5 Engine Control Module (ECM) 6 Anti-lock Brake System (ABS) control module 7 Transmission Control Module (TCM) 8 Central Junction Box (CJB) 9 Gateway Module (GWM) 10 Dual Battery Module (DBM)

is operated to crank the engine. The GWM is connected to the ABS (Anti-lock Brake System) control module via the high speed
CAN bus. With the vehicle stationary and the engine off after an ECO engine stop, when the driver releases the brake pedal
the ABS control module senses the reduction in brake pressure. This change of brake pressure state is sent as a high speed
CAN message which is received by the GWM and the ECM. The GWM reacts within 105ms to instruct the DBM via the LIN bus
to operate the two contactors in the DBJB to supply the sensitive loads from the secondary battery and supply the TSS motor
direct from the primary battery.

When the engine is running and the generator is supplying power to the vehicle systems, the GWM again instructs the DBM to
operate the two contactors in the DBJB to supply all vehicle systems from the primary battery and the generator and to isolate
the secondary battery.

Secondary Battery Charging

The DBM also controls the charging of the secondary battery. The GWM contains electrical load management software and
monitors both batteries for their state of charge. The primary battery is monitored by the BMS control module which is
connected to the DBM via the LIN bus. The DBM communicates the primary battery condition to the GWM via a LIN bus
connection. The GWM sends a signal to the DBM via the LIN bus to instruct it to apply charging from the generator to the
secondary battery when required. The contactor 2 is closed by the DBJB to complete the secondary battery circuit, and the
generator output is applied to the secondary battery to charge it.

The generator output is controlled by the GWM which monitors and controls the electrical load management system. The
generator is connected to the GWM by a LIN bus allowing the GWM to control the output of the generator to maintain electrical
system load requirements and battery charging.

Electrical Load Management

The electrical load management is controlled by the GWM and the BMS control module.

The GWM will monitor the vehicle system power loads before and during an ECO engine stop.

Before an ECO engine stop, the GWM will transmit a signal to system control modules on the CAN bus to request a power save
on all electrical loads and set a minimum electrical value override. The GWM monitors the vehicle electrical loads and will
inhibit a ECO engine stop until the load current is at a value low enough to be supported by the secondary battery.
If the electrical loads cannot be reduced sufficiently, the GWM will inhibit the ECO engine stop.

When the engine is stopped after an ECO engine stop, the GWM will continue to monitor the primary battery state of charge.
If the primary or secondary battery voltage falls below 11.0V, a level which will result in degraded starting performance or
possible primary battery damage, the GWM will initiate an engine start.
System Inhibits

The ECO stop/start system is inhibited if the dual battery system is not be capable of preventing electrical loads on the
vehicle being subject to unacceptably low voltage levels during ECO stop/start operations due to a fault.

ECO stop/start inhibit monitoring of the primary battery is performed by the BMS control module. If the primary battery voltage
is too low to support an ECO stop/start, then the BMS control module will send a message to the GWM on the LIN bus to
suspend ECO stop/start.

The GWM monitors the secondary battery and the dual battery system components. Any fault found will cause the GWM to
inhibit ECO stop/start and the GWM will record a DTC (diagnostic trouble code).

Fault Diagnosis

The GWM performs passive and active diagnostics on the dual battery system to determine the status of the system
components.

Passive diagnostics can detect faults in the DBJB and can check for stuck open or closed contactors and failure of DBM
contactor command signals.

Active diagnostics is a routine to test the capability of the contactors to respond to open or close command signals sent from
the GWM to the DBM. This routine also checks the FET's (Field Effect Transistors) activate as required. (Refer to Dual Battery
Junction Box below for description of FET operation)

The GWM will also check the dual battery system components for faults in a controlled environment when the generator is
providing a charging output. This will ensure that the detection of a fault will not result in sensitive electrical loads being
subjected to low voltage which may occur during an ECO stop/start with a fault present.

The GWM will illuminate the charge warning indicator in the instrument cluster if fault is detected in the dual battery system
which will result in a degraded power supply.

If a fault is detected the GWM transmits a CAN message to inhibit ECO stop/start operation. In some cases it will record a
DTC, display a warning message in instrument cluster and also illuminate charge warning indicator.
