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 (central junction box) 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 0 - Ignition off
- Power mode 4 - Accessory
- Power mode 6 - Ignition
- Power mode 7 - Engine running
- Power mode 9 - 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. Transport mode also inhibits some electrical loads when the engine is running to ensure that the battery is never discharged while the engine is running.
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 System Component Location
Absorption Glass Mat Battery
To counteract the extreme power consumption of a Stop/Start system and/or the Park Heat feature, 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 fiberglass mat compressed between the lead plates.

Battery Monitoring System (BMS)
The BMS was introduced due to fuel economy benefits, battery life optimization and enhanced diagnostics.
Moreover, optimal battery health is a fundamental factor in the correct operation of the Stop/Start system. Therefore, the BMS calculates and communicates the battery status.For additional information, refer to Starting System

BMS Plate
The BMS plate is a metal plate that is bolted on top of the BMS unit on the battery negative terminal. The plate is used to secure the battery negative cables and the ECM (engine control module) earth to the battery negative terminal.
Voltage Quality Module
During an engine Stop/Start cycle the Voltage Quality Module (VQM) maintains some of 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. For additional information, refer to Starting System
