CONDITION SUMMARY

SITUATION:

An issue has been identified on certain Land Rover vehicles within the listed Affected Vehicle Range where, due to a Connected Diagnostic Services (CDS) software issue, the Powertrain Control Module (PCM) may switch off within 5-10 minutes of a drive cycle while the vehicle is in motion. Should the PCM switch off, the engine will cut out with no warning. Driver assistance systems such as brake boost and power assisted steering will continue to operate absent of engine operation.

Engine cut-out without warning while driving may pose an increased risk of a crash.

ACTION:

Retailers are required to HOLD affected new vehicles that are within your control and refrain from releasing the vehicles for new vehicle sale pending completion of the procedure(s) detailed in this Technical Bulletin. Unsold vehicles should have this performed as part of the Pre-Delivery Inspection (PDI) process but must have it completed prior to vehicle handover to the customer.

Affected vehicles in the hands of customers will be updated with Software Over The Air (SOTA) as detailed below. If a customer requests assistance in completing the SOTA update, they may visit an authorized retailer to have this completed and the required software update performed.

The software update to the PCM will be performed through SOTA and so an authorized retailer visit is not required unless the vehicle is already at the retailer, or a customer wishes for the retailer to perform the update.

SROS

NOTE: If the customer requests to have the software update completed using Pathfinder, the option has been created to enable the retailer/authorized repairer to submit a claim. Option codes should only be claimed if the SOTA cannot be completed.
