TECHNICAL SERVICE BULLETIN

Reference Number(s): LTB00432NAS2, Date of Issue: March 29, 2012

LAND ROVER:	2010 - Onwards Range Rover (LM)
SECTION:	501
AFFECTED VEHICLES:	Range Rover (LM) VIN: AA304426 - Onwards Model Year: 2010 - Onwards

NOTE: ISSUE '2'

CONDITION SUMMARY

Situation: The Deployable Side Steps may deploy after the vehicle has been parked in an unlocked condition of five (5) minutes or longer. The side steps will then remain in the deployed position until a door is opened and closed. This may be due to a low battery voltage condition causing the Running Board Control Module software logic to interpret a 'Locking state unknown' message incorrectly and deploying the side steps.

Action: In the event of a customer concern of the above, refer to the REPAIR PROCEDURE outlined below to update the Running Board Control Module software.
