AFFECTED VEHICLE RANGE:

2010 Land Rover Range Rover (LM) V8-5.0L SC Page 159

NOTE:

Verify VIN in DDW to verify Service Action applicability prior to undertaking any repairs.

Range Rover (LM) VIN: AA310605 - AA314568 (specific VINs)

Model Year: 2010

CONDITION SUMMARY:

Situation:

A limited number of 2010 model year Range Rover vehicles memory seat Electronic Control Units (ECU) will hold the Controller-Area Network

(CAN) bus awake if the vehicle ignition system is switched on within three seconds of adjusting the seat, leading to a battery drain of approximately

2.5 Amps until the next ignition cycle. When the battery voltage goes below 8.5 volts the seat module goes off-bus. When the voltage recovers, the

application software is likely to lock up; this in turn will cause the CAN bus to stay awake, leading to a flat battery / non-start condition.

Action:

Retailers are required to HOLD all affected vehicles in the above VIN range that are in their control and refrain from releasing the vehicles for new

or used vehicle sale pending completion of the rework action detailed in this Technical Bulletin. Vehicles must not be released until successful

reconfiguration of the Driver's Seat Control Module. Affected vehicles in the hands of owners should be repaired at the next available opportunity.

At the time of customer appointment, ensure that all outstanding service campaigns for each individual vehicle are identified and allocate sufficient

time and resources to complete all campaigns. For cars in Retailer inventory, this Service Action should be performed in conjunction with the

vehicle Pre-Delivery Inspection (PDI).

PARTS:

No parts necessary

TOOLS:

IDS with IDS-DVD119_V8.03 or later and Calibration File 20 or later

Midtronics PSC-550 Vehicle Power Supply
