306 XRDT Immobiliser Problems?

Hi,
I own a `94 xrdt, i have been away for 5days and i have come back to
start my car and i get ignition (no crank on engine) then the
headlights flash and the dash led flashes, i have never seen this led
flash before so i presume its a problem with my immob.
The immobilser is the standerd 306 key fob remote, but the remote
buttons do not work so therefore i have been locking it from door
locks.
I have never encountered this problem before.
Any ideas?!?

I am also after a fuse chart layout diagram for the fuse box under the
steering column.
Thanks.

 

Or use the `behind the rear seat` immobiliser reset trick.

3 door or 5 door?
if 5 door the ecu is under the osf seat
if 3 door its behind the osr trim(next to pass seat)
in both cases check the connectors
if there is a two pin connector thgen simply connect the two wires and your
car will start
as for the alarm remove it and have an aftermarket one fitted (or DIY)

 

if it has deadlocking

 

I'm sure the XRDT has?

Jim

 

i concur but its still a variable
also in my experience these alarms are so unreliable its still worth
removing and by passing

 

I haven't had any major problems - I was merely commenting that the
immobilser can be reset simply by disconnecting and reconnecting two
connectors inside the back of the rear seat.

most likely case is that the immobiliser kicked in after low battery
voltage.
if you always used the key locks and not the remote then you would
never activate immobiliser.
make sure you have plenty of power in battery then put ignition onto
second position and press ultrasonic button on right hand side of
steering cowling within 5 seconds. this will deactivate alarm and
immobiliser.
indicators will flash when applied correctly.

 

That button on the side of the cowling was not plugged in, nor can i
see where it plugs, i cant see the battery voltage being low as it has
a new bosch battery on it, maybe i disturbed an ignition lead while
lowering the cowling? i cant seem to make it happen again, it would
just be nice what caused it, otherwise it could come back anytime.

 

if you’re headlights flash then there is definetly a plug there for
the switch.
just a case of finding it.
it is the only way of disarming alarm/immobiliser without bypassing
extreme cases the wiring is corroded at n/s/f wing
