Hey all.... been using the forum for a short while now as a non memeber! great forum!!!

anyways i had my 156 jtd 2.4 for just over a month now and i have started getting immobilser probs!
it just says code
i checked the dredded antenna and it reads 4.9 ohms (is that good???????)

can any1 help me and see what else i should check... im shure i read somewere that the battery helps... but its got anuff power to turn the engine over so i guess its anuff to power the immobiliser...

Try the wiring into the relay blocks in front of the battery - on my JTD corroded wiring there caused the "code" problem the day after I bought it. Could be the relay itself, but unusual - usually the wiring into the relay mounting block which may be faulty even if it looks OK...official guidance is to "stress" the connections - the wires may come away in your hands......

Test the voltage to the immobilser box when you run the starter and see if you have
more then 10V otherwise the immobilser box don't work properly and you may have imobeliser problems, starter motor turns the engine over but draws a lot of power and the battery provides less power now when it is cold, so it can happen that you get so much voltage drop to the immobilser box so that the immobilser is not functioning properly, a well charged / (new) battery usually helps.

the fault will probably be minor and cheap, finding it is your issue.

you need an auto electrician if you cannot do it yourself
