Bonneville T120 Engine Management Light

Have you checked to see if there is a fault code in your system?

Checking fault codes:

• Hold “I” button and turn ignition switch to ON.
• Release I button when “DTC” appears on the left window.
• Read the code. It'll be a P followed by four digits.
• P0000 is no codes

 

Have you checked for stored DTCs?

 

Sorry. I hate acronyms too!

Fault codes. If the error light is on there should be fault codes stored. You can get them yourself and look up the values on the web.

The steps are:
Hold the "i" button on the left
Turn the key on while holding "i" button
The display should cycle through to DTC, release the "i" button.
It should show the codes.

Good luck.

 

I have tuneecu, but you don't need anything to display the codes. Just follow the steps (I think I have them all in order)

 

For a code reader you could try one of these below.
I switched my 765 on with the tank removed and it put the EML on. This soon sorted it.

Readers with leads are ok with earlier bikes but don't work on later stuff as it has to be by Bluetooth.
Can someone confirm the reverse isnt so meaning you can use Bluetooth on older models?



On later stuff you also need to balance throttle bodies by electronic readings hence why I bought it initially.

So, to the OP David, did you resolve the problem with the engine light?

 

The engine management light on a motorcycle monitors a variety of features. The light should turn off a few seconds after ignition. If the light stays on after this time, you could have problems with emissions, air intake, or fuel.

 

Great info on this thread; didn't realize the 'i' button would display ECU codes.
In any case, I just received the DealerTool OBD scanner made for Triumphs and made in the UK; per their instructions, I downloaded their software and drivers from their website; not used it yet.

Oh, one last thing; I have noticed for the first time that my check engine light comes on when I move the ignition switch to Run but disappears after the engine starts; had a senior moment when I first noticed it and wondered if it had always done that - oh well
