Hi Members,
For almost 6 months now, we've had a Range Rover Sport 2007 with non start issue. The car start at times and most times doesn't, only ignition on nothing not even cranking. When refuses to start all hazards lights keep flashing even after removing key from ignition. We usually disconnect battery give it time maybe hours to a day then try to start and yes it starts or sometimes fails and keep trying till it starts.
PCM had code:
P1623-00 Immobilizer Code Word/ID Number Write Failure- No sub type information
Bought new key and programmed, bought a new alternator as suspected to be the problem & changed and programmed two different instrument clusters but still nothing. Programmed BCM as new control unit using SDD but still problem persist.
What could be issue and how to resolve it. Any help will be highly appreciated.
Regards.
