I had same problem, when a door lock broke, the car thinks it has been broken into once the alarm goes off. Mine started going off randomly when this lock broke. You have to reset the alarm system, with my 1990 Acura it was reset finally by putting key in door lock and turning key back and forth 3X. In my car, it was OK to do the key in door lock cycle in the passenger side door lock, but Acura dealer told me not all Acuras will reset it via passenger side key cycling, some require driver door lock key cycling only. I was lucky since my driver side door lock was currently useless, that my car allowed it to be done by key cycle on pass. door lock. But try that and if it doesn't fix it, just call acura dealerships until someone tells you the right answer. In my situation it took 3 dealerships with 3 different answers until this was the right one for my 1990 Legend.

PS I was told you can't disable alarm since it is all integrated into the battery and starting system, but read on another post that someone disableld theirs by disconnecting the horn.

Hi. Anything over about 300 milliamps is generally to high. illumi sounds like an abbreviation of illumination. with the fuse out try all your lighting, interior lights, dash lights ect. and see what doesn't work. a common problem is boot lights sticking on as they often cant be seen with the boot closed.

doesn't need a rebuild
try an oil change for the transmission as it indicates dirty oil and sticking balves
should have been changed at the 60000 miles mark or 120,000miles
run fault codes to check for torque converter clutch servo/ solenoid problem

Hello, I suggest you check both positive and negative battery terminals for corrosion . Remove them and clean them with a wire brush.

Three places I'd check first:
1: Check for leaks, including the plastic pressure tank if your Camry has one. Small leaks can let the pressure drop without losing any water, but the lower pressure lowers the boiling point of the fluid, which sets up a cycle that makes the water turn to steam and actually get hotter because it can't circulate properly.
2: Check to make sure the water pump is working, or at the very least that the pulley on the water pump is not slipping. SImilar to #1 above, it the water isn't getting circulated from the engine into the radiator, it can't be cooled down.
3: Check for excess moisture in the exhaust. A leaky head gasket can cause both loss of pressure and steam buildup (ala #1 above) as well as pushing hot exhaust into the cooling system. Also, check for any foam in the oil, as this is an indicator of a head gasket problem as well (water mixing with oil makes foam)

Have the battery and the alternator tested.

1990 Acura... | Answered on Apr 01, 2014


the diffr,. is QUALITY. in price, there is no low end limits to junk,,,,,!!!!
I use "STANT" brand, and price is not an issue, (life is)
so many questions, why not read the manual, and not ask others
to type this all out.
alldata.com log in and read. /??????
or a real FSM> buy one. ?
1: drain coolant.
2: follow top rad hose to the STAT housing. (below throttle body)
3: remove housing.
4, and stat, put in new, with wax side to water jackets and bleed jiggle pin UP HILL. in your case UP .
5: new gasket, and reverse above.

that works on 99% of all cars, the gaining access part varies
by car engine, and body type.

did you google for this, with engine size,
or youtube it? i guess not.

if found that with 1st google hit, am i luckly/?

no country stated.
nor if its factory or aftermarket alarm
making a very old alarm work right , with no books is a problem.
its just a computer, programmed to be and alarm and will only
work right when all sensors work prefect.
and is unlikely after, 24 years of rain and dirt and rust.
very hard to fix. (and i know how. )

id have already took it apart and found what smoked.
and why. ID the the actual wire , conn, or switch that smoked
then see if someone put the wrong fuse in that circuit. (bigger is bad)
its and old car, expect stuff like this, and more to follow.....
