90 Camry Security System Disable

[Mike C.]

I own a 1990 Toyota Camry which is equipped with a Fujitsu Ten (Toyota)
Vehicle Security System. I recently lost the only keyless remote that
came with the car and have had no luck finding a replacement. The alarm now
goes off when the door is opened and won't let the car start (had to disconnect the battery). Even if a replacement remote were available it would probably cost more
than the alarm system is worth to me. As such, I decided to simply remove the security system but it is sophisticated enough to disable the starting circuit when the ECU is
unplugged. I have tried to obtain service information on the system
from Toyota to no avail. They show the ECU part number in their system
but that's it. I have the factory electrical manual for the car and
unfortunately there are no wiring diagrams showing how the security
system is wired into the car. Although the system appears to be factory
installed (the wiring loom does not look aftermarket), the car's
original owner thought it was dealer installed. Can anyone
help me locate information on this system, ideally in the form of a
schematic showing what the 18 different wires connect to on the car?
With this information, I'm sure I could restore the car to running order
less the security system. I have even tried contacting Fujitsu Ten's car
electronics division with no response.

A description of the ECU is as follows: Toyota part number
00398-00910, serial no. 900219M256

Also printed on the ECU, FCC ID: BABMW-8170 MW-8170 Fujitsu Ten
Limited made in Japan

wow....never heard of a gen2 with factory keyless entry, i seriously doubt its factory.

good luck man.

worse comes to worse, have it towed to a installer and see if they'll cut it out for you.

It is strange. The ECU has an official Toyota part number, the wiring loom looks very integrated into the under dash loom. Yet Toyota has no information available on it. It looks too good to be dealer installed...

This is a ? for 88 LE

Sorry I can't help, I know nothing about alarms.

Though I don't know how "similar" it is to a Previa alarm, but if it's anything like it, once you take the alarm out, you have to find the starter kill relay and reconnect the 12-gauge starter wires together in order for the car to turn over. Unfortunately, there are no markings on the alarm case to show what the identification of the wires are. These "true" OEM are all plug-and-play, so there is no splicing involved like aftermarket alarms.

I've got the same problem with a 93 celica. same fujitsu ten and I can't get to work now because my own car thinks I'm stealing it.
