Immobiliser not turning off

The Aus delivered cars had their immobilsers fitted locally so the international guides are no help.It's been a while since I've had to bypass an 8...

from memory you can join the two green wires which have red terminals coming from ignition switch area to over ride, also you can fit jumper wire into relay under dash . this dual relay is fitted to central lock as well i think it is a clear looking relay plate.

Thanks for the help.

Tim is correct all Aus models are after market.

The module is in one or 2 places.

The central locking receiver unit is behind the glove box.

I have posted the part number on this site to replace the Australian Aftermarket units with ones available from the US.

You will also need a matching fob.

You can fit a bypass relay to remove the immobilizer it lives under the foot well on the drivers side.

Thanks for the help. I’ll launch into it tomorrow.

So it turns out the previous owner must have had the same issue. While removing the covers under the tearing wheel to get to the relays I found someone had installed a key switch into the wiring at some stage. Naturally I didn’t have the key but I wired in a toggle switch instead and I could turn off the immobiliser. Now have the old girl starting but it won’t idle some some cleaning of the throttle body and IAC is next on the list. Thanks for the help.

Remove it all and put a 3545333 relay in.

Behind the glovebox install the key less entry if you want.

You can upgrade the 3545333 relay with a genuine immobilizer relay... think there are 2 types.

tedse21

I will thanks again for the advice. Much appreciated.

Once the stater relay is solved these are the keyless entry parts

Receiver part no. 3545654 FCC cwt5654r

Fob part no. 3545653 fcc. CWT5653T

Are a matching set.

It also appears

Receiver part no. 9148645 fcc no.CWTTFWB1G

Fob part no. 9148646 fcc no. CWTTFWB1G

That’s great info. Thanks very much for your help. I will get into that ASAP.

Hey guys, sorry to bump the thread.

Planning to sell mum's Volvo as she's too old to drive nowadays.

Car has been sitting for a few months so the battery is invariably dead. NRMA came by and couldn't get it running again due to the immobiliser (eventually got it started but battery isn't charging or holding charge), so have been investigating that until I bumped across this thread. NRMA mentioned that the immobiliser may be charging a backup battery, which has been draining the actual battery up until this point.

Anyway, short story - my question is related to the relay.

I found a 'relay' near the brake pedal with four wires coming out of it. Is this the relay I need to replace with 3545333? and will this essentially disable the immobiliser in the car?

Thanks for the help in advance.

Can you take a closer look at the relay and read the part number? Or other identifying marks. Or post a photo if you can.

jamesinc hey mate,

Yep see attached. Is it the yellow plug?

jamesinc update - pulled these out of these relays which seem to be the right ones

I have the relay mentioned above on order from Poland but I do want to just get the car started. Goddamn what a headache.

jamesinc

Yeah that transparent relay mount has dealer fitted written all over it 🤣

OldVolvo95

jamesinc bahaha, yeah that's what I thought when I saw it. Presumably the 3545333 relay will sit where the pink socket is?
