Land Rover Discovery: 12 Volt Midtronics EXP-1080 JLR Diagnostic Battery Charger

PRINCIPLES OF OPERATION

For a detailed description of the battery system and operation, refer to the relevant Description and Operation section of the workshop manual REFER to: Battery and Cables (414-01 Battery, Mounting and Cables, Description and Operation).

INSPECTION AND VERIFICATION

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:

• 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 manufacturerapproved diagnostic system).
• When performing voltage or resistance tests, always use a digital multimeter that has the resolution ability to view 3 decimal places.

  For example, on the 2 volts range can measure 1mV or 2 K Ohm range can measure 1 Ohm. 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.

• 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.

1. Verify the customer concern
2. Visually inspect for obvious signs of mechanical or electrical damage

Visual Inspection

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
5. 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

Battery Label Example

Battery Test Types

The Midtronics EXP-1080 JLR diagnostic battery charger has three types of battery test available to the technician to select:

Battery Test

1.The BATTERY TEST should be used on any battery that has started its warranty life cycle. The battery is in use and fitted to a vehicle registered to an owner

PDI / Storage

2.The PDI / STORAGE test should be used on any battery that has not yet been entered into the warranty life cycle. The battery is fitted to a NEW vehicle, but the vehicle has not yet been sold/registered to an owner

Battery Storage

3. This BATT. STORAGE test should be used on any battery that has not yet been entered into the warranty life cycle. The battery is not in use and is a Parts Stock battery and has not yet been fitted to a vehicle

Battery Tester Results Table

Flooded Battery Care Point

If the vehicle is equipped with a flooded battery, ensure the replacement battery is a flooded battery of the same specification (cold cranking amperage (CCA), battery standard (EN/SAE) / amp hour rating (Ah)) as the original battery Under no circumstances should you fit a flooded battery to a vehicle that originally had an AGM battery, unless formally instructed by Jaguar/Land Rover

AGM Battery Care Point

If the vehicle is equipped with an absorbed glass mat (AGM) battery, ensure the replacement battery is a AGM battery of the same specification (cold cranking amperage (CCA), battery standard (EN/SAE) / amp hour rating (Ah)) as the original battery, unless formally instructed by Jaguar/Land Rover

DTC INDEX
