1995 Poosible Immobilzer Problem?

[rdltd]

Hi,

I have a 1995 LS400, and recently the battery went flat ( as i was away for a month). When i came back i found the battery completely flat, could not use the plipper to open the doors, and used the key in the drivers door. When i opened the door the nothing happened. I then jumped the battery with another car at which point the indicators flashed constantly, and the alarm went off. I manually switched the alarm off under the bonnet using the alarm key, but the indicators continued flashing. On inserting the key into the ignition & turning the key i get nothing at all. the lights come on including the red immobilizer light.

I suspect the immobiliser is on but how do i disable it?

Any help would be much appreciated, and many thanks in advance for responses.

I do not know this will get rid of the problem, but I would get a trickle battery charger and hook that up for a day or so.

HI.

Did that, and tried a new battery, but no joy.

IS there any chance i can by pass the immobiliser?

See if it will reset by disconnecting the batt for 10 min or so. Of course, make sure the batt is fully charged.

no LS400 pre 97 had an actual engine immobilizer from the factory.

most likely, either the battery and/or the alternator is dead. the ALARM may have killed the motor since it was tripped but based on my experiences with the old '95 i had i doubt it.

check ur fuses.

I have a 1998 GS400 and I have the same problem as the original poster. I can't find a way to deactivate the inmobilizer. The altenator is working. The battery is brand new. And all the fuses and relays are working ok.

I actually managed to start the car a couple of times (reight after I disconnected and reconnected the battery), but overall the car wont start.

Is there a key combination insert/remove combination or a pedal press/depress combination that may disable the inmobilizer?

your car actually has an immobilizer unlike the OP, if it is indeed an immobilizer problem then no, you can't do anything with a combination of anything. you need to have the car serviced.
