Occasionally when driving on potholed roads, the flashers/hazards come on.

The Disco keeps driving, no problems. But hazards stay on until I stop, turn of engine, and click to position II, off, then restart.

What is going on? If it was the inertia switch, wouldn't the fuel pump get shut down?

Thoughts?

Ive had the same thing happen. Curious to hear what they say...

 

From the owner's manual....

pg. 15 - Doors unlock and hazard lights start to
flash when vehicle is in motion.


The inertia switch has been triggered. Stop the
vehicle and turn the starter switch off and on
again. Central door locking will be inhibited for
5 minutes. If fault continues, consult your Land
Rover dealer.

or....

pg. 17 - Door locking cut-off switch
An inertia switch, operational only with the
starter switch in position ’II’, prevents the
doors from centrally locking (or if the doors
are locked, will unlock them) in the event of an
accident or sudden impact.
When the inertia switch operates, the central
door locking is inhibited and hazards flash for
a minimum of 30 seconds or until the system
is reset by turning the starter switch on and
off, twice.

 

I did figure out how to reset. But I am trying to figure out what is actually wrong with the inertia switch. It looks like a new one is only $35, but don't want to just start slapping in new parts if there is something else going on.
