Battery, Mounting and Cables Land Rover Range Rover L322

Scheme 2

Diesel variants use a 90 Ah/950 A EN battery.

Gasoline variants use a 90 Ah/800 A EN battery, cold climate markets use a 90 Ah/950 A EN battery.

The battery is located in the engine compartment, on the passenger side. It sits in a tray and is secured with clamp plates and bolts.

The battery terminal posts allow for the battery cables to be connected with clamp type connections.

When removing the battery, ensure the alarm is disarmed and the ignition is switched off. Always disconnect the negative terminal first and then the positive. When refitting the battery, always fit the positive terminal first followed by the negative.

If the battery requires recharging, always use an approved constant current charger, designed for lead-calcium batteries. DO NOT use a fast charger, as permanent damage to the battery may occur.

Scheme 3

During production of the vehicle a transportation relay is installed on the battery positive terminal, to minimize battery drain during vehicle storage and delivery. The transportation relay provides a convenient method of disconnecting power from all of the electrical systems on the vehicle, but allows power to be easily restored to start and drive the vehicle during loading, unloading and storage.

To start the vehicle when a transportation relay is installed press the hazard warning switch, this activates the transportation relay to power up and allow's the engine to be started. If the ignition is turned on but the engine is not started the vehicle will return transportation mode after 15 seconds.

The transportation relay must be removed from the vehicle prior to customer handover.

JUNCTION BOXES

A number of junction boxes are used to distribute power throughout the vehicle. For more information on fuse ratings and circuits protected, refer to the Electrical Circuit Diagrams.

BATTERY JUNCTION BOX 2

The BJB 2 is mounted on the engine bulkhead, behind the battery.

BATTERY JUNCTION BOX

The BJB (battery junction box) is located in the engine compartment, on the RH (right-hand) side of the engine compartment. The BJB receives its main power supply from the battery via the CJB (central junction box) and contains fusible links, blade fuses and relays.

CENTRAL JUNCTION BOX

The CJB is located behind the glove box and receives its main power supply from the battery. The CJB contains fusible links, blade fuses and relays. The side of the engine compartment. The CJB also provides the main power supply to the BJB and the rear junction box.

REAR JUNCTION BOX

The rear junction box is located on the RH side of the luggage compartment, behind the side trim casing. The rear junction box contains blade fuses and relays, and receives its main power supply from the CJB.

PRINCIPLES OF OPERATION

For a detailed description of the battery system and operation, refer to the relevant Description and Operation instructions of the workshop manual. Refer to Battery And Cables - Description & Operation

INSPECTION AND VERIFICATION

1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical or electrical damage. Mechanical Electrical Generator Drive belt Drive belt tensioner Generator pulley Check the security of the generator fixings Generator Battery Battery connections Starter motor Harnesses and connectors Fuses Charge warning lamp function Engine Control Module (ECM)
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4. If the cause is not visually evident check for Diagnostic Trouble Codes (DTCs) and refer to the DTC Index.

DTC INDEX

Note. 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).

Note. When performing electrical 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.

Note. Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.

Note. 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.

For a list of Diagnostic Trouble Codes (DTCs) that could be logged on this vehicle, please refer to Section 100-00.
