Hello all, i recently had my emw light come on mid ride. My bike is now idling at an inconsistent beat almost hiccuping, I was wondering if anyone had any advice on what next steps would be. I replaced spark plugs/oil/oil filter sunday and all other liquids are at appropriate levels. The idle starts at 1250-1350 and after warming up for a couple minutes drops down to 850-1100. Should I run the 12 minute idle test? I was hoping it was a bad plug but now im wondering if a cylinder is running rich or idk. Any advice is helpful, appreciate yall

Did you re gap the spark plugs? They come pre gapped but don’t have any protection in the box so basically they aren’t gapped correct.

Couple of questions, how old is the bike, and how old is the gas in the tank? Rough idle may be several factors, the injectors could be clogged, fuel pump pressure is low, ECM is getting bad data from the lamda or other sensor. It's hard to diagnose with such limited information. First start with CDL's advice and see if you are throwing any codes. If that's clear a reflash of the stock tune might help. The adaptation in the fuel injection system might have gone off the rails if you had any bad gas go through the motor. Can you expand on the conditions surrounding when the problem cropped up, how long the bike was sitting, how many miles are on the motor, etc.

As a final thought, get some Sea Foam dump in fuel injection cleaner and run that through the injectors and see if it improves.

Thank you so much for the response, Bike is 2018 with 12000 miles, gas is 2 weeks old. I threw the following codes

P1698 5 volt sensor supply circuit fault

P2100 Throttle actuator open circuit

P1619 Headlight relay short circuit to earth or open circuit

The bike rides fine though, Its just that the idle is a little skippy. So if the throttle fully works then how is the throttle actuator failed

Seems like a blown fuse with opens. Does the headlight come on when the bike ignition is switched "ON?"

[QUOTE="NillieWelson, post: 244357
Fuel replacement and a throttle body treatment sounds great ! You should check the code that set your engine light off look up the error number so you can identify the problem the ECU detected if more serious.

O'Reilly or Autozone could probably read it if you don't have a friend with a compatible ODB reader, definitely save you some time and the light will still be illuminated until you do.[/QUOTE]

Check your battery and check the negative bracket it needs you to scratch away the paint or use lock/star washers to cut into the paint.

It does indeed, I assumed that was supposed to happen.

 

[atomsplitter]

"It does indeed, I assumed that was supposed to happen."

It is, the codes you listed, if they were actual it would not. You need to clear the codes and see if they return. Since the bike is running I would suggest you double check the ground on your battery. Also check your battery voltage before and after start.

Awesome, do I need a specific software to clear codes?

I think you can clear them right on the bike.

Here is how to view them (thanks @Traveller):

Press and hold down the "Info" button, turn ignition "on", observe window in left display until you see "dtc", release the info button as soon as you see "dtc". A code will follow with "P" and four digits. P0000 = no faults.

Ok I have finished all my mods led rear light/indicators, led front indicators, all work fine, small pod air filters and I have caped of the holes in the top of the airbox, fitted trickle charger cable, x-pipe, shoe mudguards and a few other visual mods, everything works as it should but I now...

Search around a bit, you can probably find a way to clear them ...

That only reads the codes but won't clear them. But if anyone figures out how to clear codes without extra tools or apps I would love to know.

In some cases the bike will get codes because you worked on something or the battery failed, ect. Normally the codes will clear themselves after you ride it a few times. If not then you may have an issue.

 

[MoxyDave]

Maybe try holding down the INFO button for even longer?

Maybe try holding down the INFO button, then turning the ignition back off?

I'd try it myself but my bike doesn't have any codes ...

You might be surprised by just fooling with it for a bit.

I don't know if this will work on a Triumph but it works on most cars to clear codes. Disconnect the battery then clamp a piece of wire between the positive and negative cables and let it sit for 30 minutes. This will drain all power from the car/bike and the computer memory will forget the codes. But I have never tried this on a bike so I am not sure if it will do anything. It works on my cars.

From the Technical Compendium 2:
Note • Resetting adaptions with the motorcycle connected to an exhaust extraction system may cause incorrect values to be set, causing poor engine running. Always reset the adaptions with the engine disconnected from any exhaust extraction system whilst ensuring the motorcycle is positioned in a well ventilated area.
1. Ensure the engine is cold.
2. WITHOUT TOUCHING THE THROTTLE, start the engine and allow it to warm up until the cooling fan comes on.
3. Leave the engine to idle for a further 12 minutes.

Note • As an alternative to the above process, connect the diagnostic tool, select ADJUST TUNE (see the Triumph Diagnostic Tool User Guide) and select RESET ADAPTIONS. This will force a fast adaption routine to take place in around five seconds. For this to happen, the engine MUST be running, it must be at normal operating temperature and in closed loop control mode. Under any other conditions fast adaption will not take place and may cause default values to be loaded, which may then require a normal 12 minute adaption routine to be run. Fault Indications If 'range' figures at 100% are seen, then the adjustment has reached maximum indicating a mechanical fault exists on the motorcycle. This can be due to a number of faults but the most likely causes will be low/high fuel pressure, faulty injectors or air leaks at the throttle bodies or airbox. In these circumstances, locate and rectify the fault, and reset the adaptions as described above.
