Hello!
My Eclipse is one and a half year old and has 7200 km. Three days ago, warning lights appeared suddenly on the dashboard indicating that service is required for power steering, routine maintenance, AS&G system, BSW, Parking Brake, 4WD, ASC system, TPMS, ABS, Driver assistance camera service, FCM. It is like Christmas in there!
1031

There is no speedometer anymore but the car is running fine and it breaks without problems. The other lights, the radio, the keyless ignition, the locks are fine for the moment.
A local mechanic tried to reset the computer box, could not do it and said we should replace it. Then, we took the car to the dealer who had no clue, but said we should leave the car there for a week and have all the parts replaced!
My problem is that I bought the car in Switzerland and brought it for my three years assignement in the Ivory Coast. It is still under warranty at Mitsubishi. On top of it, it should pass a technical visit next month here in Abidjan.
I am no mechanic, but I am pretty sure that the problem is the computer. We have not checked the fuses yet, but will do so. Has anyone any idea what the problem could be and how to fix it?
I would be grateful for any suggestion.
Kind regards.

How did the local mechanic try and reset it? You would need to disconnect the battery and let it sit for several hours for the capacitors to completely discharge. If that doesn't reset it and you still have all the error messages, then I do think you have an ECU problem and ANY Mitsubishi dealer should be able to replace that for you under warranty. Of course, there is the possibility that your firmware has corrupted and you only need to reflash the ECU with the newest version. Again, though, you need a dealer to do it.

Could be a simple as a blown fuse. Or a connector coming adrift.

On RHD models there is a connector that has about 8 pins up above the pedals to the left that when disconnected gives a crazy amount of faults. This scenario was used in a service skills test here in australia. Took me 35 mins to diagnose and fix it

When one system goes down, all the systems on the network throw fault codes. So if the ACC cannot control engine speed anymore because of a minor fault, the other systems will also throw codes as they cannot do the same.

it doesnt mean they are all faulty. A good technician should be able to work out from the MUTIII which is the system that has the fault and fix that, then all the other incidental codes will disappear.

A decent MM technician should be able to diagnose this quickly.

A local independent will just waste time and money throwing parts in the direction of the car.

Most time issues like this pop up where multiple errors display its normally a source of power issue ...
Make sure battery is connected properly and the alternator plug is firmly attached..... otherwiss do a complete battery disconnect turn on headlight switch to drain system... then connect battery then power on accessories then power on system (dont start engine) for atleast 15 seconds till all error code on dash settle then star engine allow vehicle to idle for 15 minutes ...this will relearn parameter.... do not rev. Don't not turn on AC... if you drive right after a battery change you will hve multiple error as vehicle ecu don't know parameter values.
If error codes still remains and engine idle erotic... then some sensor or wire plugs is disconnected or not completely connected

Thank you for this information. I have done the disconnection but not as thorough as you mentioned it and it did not help. I will try to do it your way.
