Electrical - Battery Low/Dead For No Apparent Reason

No: LTB00391 (ISSUE 1)

14 JULY 2011

SECTION: 415

FLAT BATTERY

AFFECTED VEHICLE RANGE:

LR2 (LF) w/Navigation only VIN: 8H000212 - Onwards

Model Year: 2008 - Onwards

CONDITION SUMMARY:

Situation:

The vehicle's battery may be flat, for no apparent reason, after the vehicle is parked overnight or similar period of non-use. This may be caused by

the Infotainment Control Module not shutting down correctly if the following conditions occurred at the time of ignition OFF and exiting the vehicle:

1. Customer viewing the Navigation system map; and

2. Customer engaged in an active Bluetooth(R) telephone call.

If both of these conditions are encountered, a quiescent draw of approximately 1.5 amps on the battery may be induced, leading to the flat battery

situation.

Action:

In the event of a customer concern of the above and after ensuring proper electrical system checks have been carried out as referenced in the Land

Rover Battery Care Manual, refer to the Repair Procedure outlined below to update the Infotainment Control Module software.

PARTS:

No parts necessary
