Puma Defenders have a battery disconnect sequence?

Also I love your work!

Yeah mate.
1) Lock car.
2) Unlock car
3) Disconnect battery earth within 17s (according to fsm)
4) when you reconnect the key fob won't work. You need to start engine before you can use the fob. I think it need to recode itself or something... I'll dig up some info tonight .

Amendment to above- FSM recommends:
1) Disconnect the battery ground cable.
2) Loosen the nut.
3) Turn the ignition key to the run position.
4) Turn the ignition key to the off position.
5) Within 17 seconds of turning the ignition key to the
off position, release the battery ground cable from
the battery.


So locking / unlocking not necessary. Cycle between Run and Off key positions before disconnect within 17s.

I didn't know that. Lucky nothing bad happened when I did it.

I must admit to being guilty of knowing about it, but still ignoring it completely every time I disconnect the battery. Can't say I've ever had a problem with it.

Cheers,
Jon

I think the amendment needs an amendment.
Delete item 1 as this is a heading for the procedure. The procedure is:
1)Loosen the nut of the ground cable. (don't disconnect yet).
2)Turn the ignition key to the run position.
3)Turn the ignition key to the off position.
4)Within 17 seconds of turning the ignition key to theoff position, release the battery ground cable from the battery.
This is the procedure in the workshop manual.
