Engine Light

[Dave95]

So I got an engine warning light on my lancer and I plugged an OBII scanner in and it said faulty right rear indicator, which works perfectly fine. I have LEDs in my tail lights with resistors on them so its not that, does anyone know what it might be. Because i dont want to take it to mitsubishi under warrenty only to have to take out my CAI before hand so they dont accuse that causing it.

go back to normal indicator and see if that fixes the problem

[Dave95]

I tried that and reset it, it didnt fix it

[Dave95]

I should also mention that its only the right one that it says is dodgy wish was the first one I put in, which also was the only bulb i touched with my hands

[megatron]

both or just rear right?

[Dave95]

yeah just the right

[megatron]

try replacing both, I know I had problems when I replaced mine with leds so went back to stock

[Dave95]

mlah i prefer the LEDs so much ahah. I might just take it to mitsu, whats the worst that could happen? (thats a real question not rhetorical)

[Zaphod]

Swap left-to-right and right-to-left

If the problem changes to the other side of the car, the problem is with the light or the load resistor, if the problem stays, it's wiring / something else.

If the problem does move to the other side, swap just the resistors over, and again see if the problem travels with the load resistor or stays with the LED.


Shouldn't take more than five minutes...

I'll try that blulb switching and then if that doesnt work ill take her to mitsu

[Dave95]

I switched the bulbs and now the code has changed to P0703 (Brake Switch "B" Circuit) I know I took it to a mechanic ages ago and they changed the brake light switch. so does anyone know what it could be?

Put the original standard lamps back and see if problem goes away...
