General Information - Diagnostic Trouble Code (DTC) Index DTC: Rear
Junction Box (RJB)
Description and Operation

Rear Junction Box (RJB)


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.
NOTES:


If a control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the Warranty
Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installation of a new
module/component.


Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan tool to
the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system).


When performing voltage or resistance tests, always use a digital multimeter accurate to three decimal places, and with
an up-to-date calibration certificate. When testing resistance always take the resistance of the digital multimeter 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.


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.

The table below lists all Diagnostic Trouble Codes (DTCs) that could be logged in the Rear Junction Box (RJB). For additional
diagnosis and testing information, refer to the relevant Diagnosis and Testing section in the workshop manual.
For additional information, refer to: Communications Network (418-00 Module Communications Network, Diagnosis and Testing).

WARNING: Moving parts can cause severe injury, keep clear of moving parts, never place your hands or any part of your
body near to moving parts


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:


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.


If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual, or determine if any prior approval programme is in operation, prior to the installation

System Operation
Electrical power for the charge air coolant pump is supplied from the intercooler water pump relay in the power distribution box.
When the intercooler water pump relay is energized, it connects power from the battery, via the BJB (battery junction box)
and CJB (central junction box), to the charge air coolant pump. Operation of the intercooler water pump relay is controlled by
the ECM (engine control module). The intercooler water pump relay is energized continuously while the ignition is in power
mode 6.

When the charge air coolant pump is running, coolant flows from the pump outlet through the charge air coolers, the charge air
radiator and back to the pump inlet. Supercharger Cooling Flow Diagram

HEADLAMP POWERWASHERS

The headlamp powerwash is activated when the driver requests windshield washer operation. The CJB receives the driver request via a CAN bus message from the instrument cluster. The CJB then checks for an exterior lights active signal and that a low washer fluid level signal is not present.

The CJB outputs a control voltage to a headlamp powerwash pump relay located in the EJB. The relay is energized by the CJB for a pre-determined period to allow the headlamp telescopic washers to operate.

The CJB monitors the driver washer requests and only operates the headlamp powerwash on every fourth request for windshield washer operation, provided that 10 minutes have elapsed since the last headlamp powerwash operation. The
powerwash sequence is reset when the headlamps or the ignition is switched off.


NOTE: If a low fluid reservoir level is present the CJB prohibits headlamp powerwash.
RAIN/LIGHT SENSOR

On receiving a request for automatic windshield wiper operation, the CJB interprets LIN bus messages received from the rain sensor. The rain sensor provides LIN bus messages with values ranging from 0 to 7.
A signal value of 0 is interpreted by the CJB as the windshield is dry. A signal value from 1 to 5 is interpreted by the CJB as a small amount of water hitting the windshield. In this instance, the CJB initiates a slow wipe. A signal value of 7 is interpreted by the CJB as a large amount of water hitting the windshield. In this instance, the CJB initiates a fast wipe. NOTES:


The CJB will only change a fast wipe routine to a slow wipe routine if the rain sensor value is lower than 7.

A = Clean and dry windshield; B = Wet and dirty windshield
