Stability Control & HDC Not available. Gear Box Fault. Relay Clicking on a L494.
 

Relay Clicking on the Passenger Cargo Side. Stability Control & HDC Not available. Gear Box Fault.


For the past 2 weeks. The clicking is worst in the morning, or if the car has been sitting for a while. Then lesser amount of clicking when moving from a Stop Sign or Traffic Lights.

The Relay Clicking sound comes from the Passenger Cargo Fuse Box Side of Range Rover Sport L494.



Some codes Readings:

U0402-92 Invalid data received from transmission failure.
U 3003-17 (2E) Battery Voltage - General Electrical Failure- Circuit Voltage Above Threshold (Note: the Main battery is about 8 months old)

I cannot locate the Start/Stop Battery supposedly next to Rear Fuse Box in that same cargo compartment.

U0001-81 (2E) High-Speed CAN Communication bus

U0028-87 (2E) Vehicle Communication Bus A

B1412-96 (AF) Quiescent Relay Box Component Failure (This Fault is over a year old)

Thanks for your help.
