    Just completed 350km drive.

    ECO bulb just above the fuel consumption number does not light up. (see attached)

    No DTCs.

    200 miles without logging a fault code isn't bad.

    The ECO light not coming on is minor. Is that a recent change?

    I would be more concerned about what fuel economy your car can produce.

    It was 20.5 km/ l.
    That's not normal
    Used to be 23-24

    So how to sort out eco bulb

    20.5 km/l = 48 miles/US gallon which isn't terrible.

    I don't know what to do about the ECO light, you probably would have to disassemble the dashboard sufficiently to remove the central display assembly. Maybe if you clean the wiring harness connections, all lights will resume normal operation.

    No, I don't. I misinterpreted the problem, sorry. I now see the ECO green light where you are referring to the ECO blue graphics.

    I had a brake oil leak near drivers area [probably near ecu]
    and showing C1202.

    wondering have they not secured the ecu hoses well

    got an ECU from ebay, collected by myself from USA and fixed myself
    Issues faced:
    same part no, but it wa WP_20151028_001[1].jpg s a LHD ECU would not fix 100% to my JDM
    so had to turn one steel hydraulic tube [front drivers side wheel connecting] manually and fixed
    C1203, seems like due to incorrect ECU...

    anyway after few times of calibration; everything seems to be fine now..
    my mileage also seems to have recover; however too early to comment

    ECU equals Electronic Control Unit (computer), but I'm stumped on LHD: translation?

    Ahh: Left Hand Drive!

    in here its RHD thats why JDM [Japanese Domestic Model] is popular
