It certainly could be, but I wouldn't jump to that conclusion so quickly. Leave such diagnosis' to the pros, who often zero in on the most expensive component without proper troubleshooting.
Typically, troubleshooting would start with seeing if you can get a spark at the spark plug. Then work back from that (assuming the starter is turning the engine over properly). This means spark plug, leads, disributor cap, distributor rotor, electrical continuity to the distributor and coil. About the last thing on the list is the (expensive) ECU.
Thank you so if it's a computer box how can it be fixed
Definite maybe. If it's a simple macro component like an obviously burnt out resistor or capacitor, then the damaged component can be replaced by an electrician. But more often than not, it's an integrated circuit (chip) or obscure fault on the motherbard, that only someone with the proper equipment can diagnose. The Proton is not sophisticated enough to display fault codes in its intrument cluster, as far as I know. ECUs can also sometimes develop firmware faults, that a reprogramming will solve. Again, this calls for specialist diagnosis. You can definitely find out if the ECU is at fault by locating a similar one and swapping it out to test. Locating a spare known-to-be-functional one is probably easier said than done though.

SOURCE: proton jumbuck electrical fault on
I had a similar problem with my jumbuck,2 sets of keys only one worked. Replaced battery now ok.CR2032 ,tednanango
SOURCE: hi hope you can help i have a proton jumbuck and
it is possible that you have a blown fuse, HIGH & LOW beams are usually on different fuses, most likely for safety reasons so as if either one blows at least you still have lights, check the fuses in the fuse box......hope this helps......cheers.

may be you should make a diagnostic and you can do it in a garage or you can do it by yourself if you want to do it by yourself you need some tools and you can find some good ones here: diyobd2.fr
check to see if you have a viscous fan hub connected to the fan. It so it is the hub working correctly.
Probably a bad bearing on the A/C compressor. Replace the compressor. Bearing is on the inside, not the pulley bearing.
