Toyota Computer Integrated Relay Box BYPASS

[gtmech]

The immobiliser of this 1998 Toyota Camry is playing up which is inside this Computer integrated relay box. This is a car from Australia and does not have a Transponder key system, it only has remote control fob which you use to turn off the immobiliser aswell as unlock the car at the same time. Anyone know how to bypass the IMMOBILISER side of this box? There is a 93S46 inside but from dump it looks like just the coding data for the remote itself. Theres no way to IMMO OFF the engine ecu on this car as its to old, so anyone got any ideas? Cant disconnect box as controls the locking and everything aswell of course, wont allow the car to start. What a nightmare this job is turning out to be Thanks guys

Hi gtmech,
There is a cut to the efi relay.do a continuity check from the efi relay to the integration box.

Not to sure about wire colours.I think there is starter cut(should be thick wires) and there might be ignition cut also thick wires.

I have never seen a box like this but in our country toyotas that old had a setup like that

Remote fob send out a single a remote modual pick up take single and commands the ecu to work. Looking at the ecu board I see no ariel or receiver to pick that single. Do you see any ariel around the ignition or driver door lock? Early lexus had separate immo here in the usa maybe a cross breed. In simple term fob send signal car needs to retrieve that info.

sorry buddy, i dont understand what you mean. Are you saying these are the 2 immobilisation points? Ignition is not immobilised, the starter is immobilised and the ecu is also immobilised some how (havent checked where yet), probably fuel supply or injectors etc. So are you saying bridging the relay contacts would work to bypass it? I cant imagine it being so easy but of course you never do know

yes your right, maybe there is another box somewhere for the RF Receiver, i do not know but i do know that if you disconnect this box the car wont start and wont lock or unlock anymore either. No aerial around ignition switch, this car is NON-TRANSPONDER system, its a pile of s**t, no one in there right mind would want to steal it, why the car has an immobiliser i dont know, toyota could have saved money. Even the owner hates his car,

Does the engine light come on when you put the ignition on.If not Bridge pins on efi relay and check if engine light comes on
