Range Rover Evoque: Central Junction Box (CJB)
CAUTIONS:
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
When probing connectors to take measurements in the course of the pinpoint tests, use the adaptor kit, part number 3548-1358-00
NOTES:
If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the warranty policy and procedures manual (section B1.2), 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 a current 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 diagnostic trouble codes 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
Where an 'on demand self-test' is referred to, this can be accessed via the 'diagnostic trouble code monitor' tab on the manufacturers approved diagnostic system
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 central junction box, for additional information refer to the relevant Description and Operation section.
For additional information, refer to: Communications Network (418-00 Module Communications Network, Description and Operation) / Communications Network (418-00 Module Communications Network, Description and Operation).

Dsc warning lamp
The amber DSC warning lamp in
the instrument panel illuminates
briefly when the ignition is
switched on and extinguishes when the engine
is started.
If the lamp flashes while driving, the DSC
system is active. If the lamp illuminates
continuously while driving, there is a fault with

Disabling dsc
Safety may be reduced by
inappropriately disabling DSC. In the
majority of driving situations, and
particularly on-road, it is
recommended that you do not disable
DSC.
In some driving conditions it may be
appropriate to disable DSC to improve traction.
These conditions include:
