Frelander 2. Manual — part 458
• NOTE: The fusible links are mounted on the inboard side of the BJB behind a series of removable covers.
The CJB is mounted behind the glovebox and receives its main power supply from the BJB. In addition to containing blade
fuses, the CJB is the main controller for a number of vehicle systems. These functions are outlined in the relevant sections
of this manual.
The AJB is located beneath the luggage compartment carpet, adjacent the spare wheel well. The AJB is a modular design,
and comprises up to 3 individual elements depending on vehicle specification. The AJB contains blade and J-case fuses,
and relays to distribute electrical power to systems used at the rear of the vehicle. The AJB receives its main power supply
from the BJB.

Starter fuse
Incorporated in the cable between the battery and the starter motor/generator is a CAL3 starter fuse. The fuse is mounted
adjacent the battery positive terminal and is integral with the cable assembly. In the event of fuse failure, the complete
cable assembly must be replaced.
Wire Color Codes
New wire color codes have been introduced in the Electrical Circuit Diagrams. These new codes are shown in the table
below.

Tracer wire color codes are separated from the main wire color code by a hyphen, thus BU-RD equates to a blue wire with a
red tracer. For more information, refer to the Electrical Circuit Diagrams and the Electrical Library.
POWER MODES
The CJB controls the power supplies for the various vehicle functions. There are 9 power modes available which are used
by various systems to determine the operating condition of the vehicle. Only 3 of these modes will be noticeable to the
driver and technicians as follows:
Power mode 4 - Accessory
Power mode 6 - Ignition
Power mode 9 - Engine crank.
Transport Mode
All new vehicles will be delivered from the factory in transport mode. Transport mode replaces the traditional transit relay
and inhibits a number of electrical systems and features to eliminate quiescent drain from the battery during delivery.
When the vehicle is in transport mode 'transp' will be displayed in the instrument cluster odometer.
To remove the vehicle from transport mode, the Land Rover approved diagnostic system must be connected during the
Pre-Delivery Inspection (PDI). For more information, refer to the PDI manual.
Stop/Start Vehicles - From 2010 MY
Component Location
The TD4_e is the first Land Rover fitted with an intelligent ‘Stop/Start’ system; the following components have been
introduced to support the Stop/Start vehicle.

Absorption glass mat battery
Absorption Glass Mat Battery
To counteract the extreme power consumption of a Stop/Start system, a high-performance battery based on Absorption
Glass Mat technology has been introduced. The battery owes its superiority over a conventional battery to the ‘absorbent
glass mat’ which is a fine fibreglass mat compressed between the lead plates.
For additional information, refer to:
Starting System
(303-06C Starting System - TD4 2.2L Diesel, Vehicles Built From:
01-03-2009, Description and Operation).
Battery Monitoring System
Optimal battery health is a fundamental factor in the correct operation of the Stop/Start system, therefore to calculate and
communicate the battery status a Battery Monitoring System (BMS) module is introduced.
For additional information, refer to:
Starting System
(303-06C Starting System - TD4 2.2L Diesel, Vehicles Built From:
01-03-2009, Description and Operation).
Voltage Quality Module
During an engine Stop/Start cycle the Voltage Quality Module (VQM) maintains the vehicle’s electrical systems by
supplying a support voltage around the vehicle's electronic components during an engine restart. This allows crucial vehicle
systems to continue uninterrupted when there is a sudden draw of current from the battery.
