Applicable to the following vehicles
Jaguar
XJ / X351 10MY onwards
Jaguar XF / X250 13MY onwards
Jaguar F-Type / X152 All
Issue
The Remote Function Actuator (RFA) also known as the Keyless Vehicle Module (KVM), may fail to correctly download software on occasions. This can result in SDD reporting that the RFA is Off Bus by displaying a RED cross in the networks integrity screen and SDD not being able to recover the module.
Cause
This may be as a result of low battery voltage or a break in continuity of diagnostic connection during the download or a corrupted software download file.
Action
Symptom Driven Diagnostics (SDD) now contains a service application from DVD137 P7 onwards that can be used to recover the (RFA) where a download has previously failed. You are required to remove and refit Body Control Module (BCM) Fuse 17, note this must be done during the start of the Software Download process at the point where SDD displays “Starting SWDL Job”. This will provide you with a 10 second window to complete this process. If successful, SDD will receive a response from the RFA and continue with the Software Download process. If not successful the first time, repeat the above process again until successful.
Note
Modules returned for this issue and found to recover when tested may be returned as No Fault Found (NFF) & accounts debited accordingly.

JLR Symptom Driven Diagnostics (SDD) for Independent Repairers: Diagnostic Software / Module programming subscriptions – without security access – can be purchased via TOPIx (From the User ID – Options Menu – Programming subscriptions – click add). Module programming – with security access – is necessary to program the IPC, BCM, ECM (PCM), KVM, as well as keys. Licensed locksmiths and independent repairers must be active members of the National Automotive Service Task Force (NASTF) Vehicle Security Professional (VSP) registry and will need to purchase a subscription to Independent Module Programming with Security Access to program these components. Currently we are only able to support yearly module programming subscriptions with security access. SDD will only support Jaguar vehicles built from 1995 MY onward.
