Engine Light is on when my Jimny Sierra is running.
Does anyone knows how to fix it?

Its a European diagnostic protocol that was adopted under Australian Design Rules, most scan tools support this.

Can only comment on other cars namely Mitsubishi how we cured some problems (ECU)with engine light on !
Many stated check and remove all sensors leads etc , but we found a simple cure that often works .
1/ turn off ignition .
2/ remove the fuse that turns off the engine light .
3/ put ignition on , obviously no engine light comes on .
4/ ignition off
5/ fuse back in
6/ ignition on but dont turn engine over
7/ you will often hear "clicking" as the ECU reboots all the sensors it takes average 20 -30 seconds .
8/ turn off
9/ restart car light now often goes off !
* this works I was told by a guy who worked on ECU's as the system can lose functions on odd sensor / chip etc by dust , moisture or even Alternator surge when battery is low in winter , it has worked many a time and worth a go ! Xx
