Starting The Application - Auto Stop/Start Health Check Service Instruction

NOTE:

Performing any of the actions listed above can cause the fuel adaptions to be cleared, this will cause a short term inhibit condition for the Auto Stop/Start system and is a known and expected vehicle reaction. Normal Auto Stop/Start functionality will return when the fuel adaption has completed
Should a customer express this concern, while there are a number of inhibit conditions possible the fuel adaption is the most likely following a very recent repair by a retailer. The stop start health check is the only guided diagnostic used by Jaguar Land Rover to confirm which if any inhibit condition is present when a vehicle is presented to a retailer
This guided diagnostic is a health check which displays any Stop/Start system inhibits present. It will not diagnose anything as the various system inhibits are a normal function of the Stop/Start system. To resolve and clear all other Stop/Start inhibits that are present - follow the instruction below
