ISSUE ‘4’ CHANGES ARE HIGHLIGHTED IN GRAY

SECTION:  205

‘Transmission Fault’ Displayed with DTC P186D Stored

AFFECTED VEHICLE RANGE:

CONDITION SUMMARY:

Situation:  The driver warning message ‘Transmission Fault Stop Safely’ may be displayed in the instrument cluster message center, Diagnostic Trouble Code (DTC) P186D and possibly P080A / P0806 may be stored in the electronic rear differential control module, and the Dynamic Suspension may lower.  These issues may be caused by the Electronic Torque Managed (ETM) rear differential motor being energized while the motor brake is still partially engaged, resulting in mechanical wear of the motor assembly which may lead to a stuck actuator and DTC P186D.

NOTE:  After the new differential motor has been installed, it is imperative that the new software is downloaded to the Rear differential control module.  Failure to carry out this instruction will result in a future repeat repair.  Once the new software has been downloaded, the software stored in the Rear differential control module should show 7H42-4C045-A(D) or a higher alphabetical character for vehicles pre-2010MY and 9W83-4C045-A(D) or a higher alphabetical character for vehicles 2010MYonwards. 

 NOTE:  To complete the repair the new software must be downloaded and the on demand self test (ODST) concluded.  SDD will run the ODST automatically as part of the software download to the Rear differential control module; follow all on-screen instructions to ensure the ODST is successfully completed.  The ODST configures the Rear differential control module to ensure that it knows where the clutch biting point is internal to the axle assembly.  After the ODST has completed successfully, clear DTCs and perform an ignition cycle; read DTCs and confirm none are present.  If DTCs remain, follow normal SDD diagnostic procedures.

Action:  In the event of a customer concern of the above, refer to the Repair Procedure outlined below to replace the rear differential locking motor assembly and update the Rear differential control module software.

PARTS:

 NOTE:  Rear differential motor service kit part number LR032711 may be used only if LR032712 (remanufactured component) is not available. 

TOOLS:

IDS with latest IDS DVD; software first available on IDS-DVD125_V5.03 and Calibration File 66

Land Rover-approved Midtronics Vehicle Power Supply

Refer to Workshop Manual for any other required special tools

WARRANTY:

 NOTE:  Repair procedures are under constant review, and therefore times are subject to change; those quoted here must be taken as guidance only. Always refer to DDW to obtain the latest repair time.

DDW requires the use of causal part numbers.  Labor only claims must show the causal part number with a quantity of zero.

Normal warranty policy and procedures apply.
