Ecs (electronic Control Suspension) Options

[bumpn]

hey guys i was just wondering if any body could tell me why my ecs button wont work on my 1992 mits 3000 gt sl 3.0L non turbo?? also is it possible that the ecs computer can damage the ecu if not functioning properly

Ha! You must have plastic and buttons from a VR4. I don't think any of the NAs or SLs had ECS. Check behind the button, I bet there is nothing there.

I had a '93 NA with an active aero wing on it - no motor in it, but....

Spyder SL's had ECS (IMG:style_emoticons/default/thumbsup.gif)
Also, im pretty sure some regular SLs had ECS. not sure what year they stopped doing that...mid-95 maybe when they killed it on the vr4

Damit... why don't any of my toys have those cool ... toys.

yupp mine derfinately has the ecs system i found the computer in the hatch... i just dont no how to tell if its working or not and if it isnt working properly if i shood un hook it to prevent engine ecu damage

Do you have any ecs lights coming on? usually it will light up as it goes from tour to sport settings also if there is a problem it will default to sport mode, a simple test with engine stopped is to when pressing the esc switches whilst someone listens on at top struts you will hear a click as the disc valves in struts move.
It could be a number of things, if you have two ecs lights on sport and tour flashing its usually the wiring on the top struts broken or shorting out, the fronts are the usual suspects, the best way to check these is to remove them they are only about 12 inches long and check each wire with a tester, if the bulbs are working and all the wiring is good then it will be the ecs ecu that is at fault, the ecs ecu does not affect the main engine ecu.

ok thats good to know so then the reading i did must be false when it says the ecs can damage the main car ecu...i will check the wires on the towers when i get a chance today and will keep you all posted.. as for the lights there is no tour and no sport light and i cannot make them come on?? any ideas?

[enigma48]

do all the tests first if its all alright take a look at the ecs bulbs in the instrument panel, its very easy to remove, to identify the ecs bulbs they are about 1 inch long, if they are blown, you will need to get some from mitsy dealer.

ok so i finally checked the bulbs in the instrument cluster and they appear to be good so far

[enigma48]

if the bulbs are not working then disconnect the ecs ecu and take the top off and look for corrosion on the circuit board as the caps do leak after time if it is corroded you need to source another one.

Only 95 spyder SL's. 96's don't have ECS. ECS was standard on SL models from 91-95 and R/T models from 91-93 (optional in 94 I believe) and also optional on ES models from 91-93.

thanks for the great advice so far...my car is a 1992 sk model so it does have the ecs as i located it in the trunl/hatch and unplugged the 2 plugs out of it. right now the car isnt here as im getting a new brake line put on it but i will attempt to pull the unit out when i get the car back and inspect it for leaking caps... from what i could tell tho there isnt much room in there to work with and looks to be a challenge to get the bolts out so ill see what i got to do to get it out and keep everybody updated

[bumpn]

i apologize for double posting but i finally got the ecs computer out of the hatch of the car and i havent found and thing seriously wrong with it other than one cap with blue stuff on the top of it and stuff on the bottom and on the board... i cleaned the board up really good and replaced back in car with no luck still... what is my next step guys?? i took my main engine ecu out that i just had rebuilt and noticed two leaking caps already?? does the main ecu have any bearing on the ecs ability to work??  ecs.jpg ( 311.05K ) Number of downloads: 11

Notice the blue stuff on just the one capacitor in this pic...this is the only thing i can see defective on the ecs computer

[enigma48]

what sort of stuff? sounds like the caps have been leaking acid its very corrosive and will burn the tracks on the board rendering it fubar!


Tony

[bumpn]

ya i cleaned all the acid off the board which wasnt much but i did get everything ckeaned up and i still dont have no functionality out of the ecs...my next question is going to be reguarding the main ecu and if it has any bearing on the ecs system or not because i know i have some leaking caps in my main ecu

[enigma48]

both ecu's work independantly, if the caps are leaking on the main engine ecu you should get the caps replaced ASAP the acid leaking from the caps will destroy the board, the caps are very cheap to buy but you will need a professional electronic expert to fit them.
All the info regarding changing the caps and what to look for is in this link:
