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

 

If it's still on when you arrive home you should connect an OBD reader to the connector under the seat and see what fault code it shows.

 

I don't. I've borrowed one each time (twice) my engine management light came on.

 

I did a long weekend trip on my '17 T100 in the mid August heatwave, including most of the M40 at a steady 70. My feet (being so close to the engine cases) cooked so I know the bike got stinking hot, but no sign of the management light at all.

Hope your bike is OK.

 

Sorry David, but I can't help with diagnosing why your EML is tripping. But I can recommend an OBD2 reader.

I needed to buy one recently when I tripped the EML on my Tracer 9gt by running the engine on the centre stand. Apparently the ABS module can't handle that and threw a fault code.

I bought a THINKOBD500 reader and a 6 pin adaptor to connect it to the bike. Reader was about £26 and £9 for the cable. The reader instructions were found lacking but there are plenty of useful guides on youtube to be found.

 

Not to be a smart a** but why not try the built in option first just to see if you even have a code?

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

 

@David Aldworth: I also can not help you with the diagnostics. When riding with our two T120 my with and I had never such problems. In May this year we did a 600 km long-run on the motorway to Italy without any issues. I did once a 1.000 km tour in two days on different kind of streets also with no issues. I can't imagine that riding on motorways could lead to this "problem".

 

There are dedicated motorcycle scanners/readers but they are really expensive. More for motorcycle workshops, etc, I think.

I thought I'd take a punt on a cheaper generic reader and so bought the THINKCAR model. Happily it worked for me..

By the way mate, you're not being dumb, just rightly cautious being on new ground.

 

I use an OBDLINK LX Bluetooth connection and Tuneecu app on my phone. Mainly used to balance throttles and reset service light.

 

Hi guys, just reading the posts on a reader for engine management for your bonnie, try this it's the only one that works properly.

 

That's the one I have and it works well on a 2018 765 rs.
You can read codes, balance throttle bodies etc.
Paid £90 for it UK.

 

I use my LX reader on a 2004 st, 2010 speed triple and a 97 and 99 daytona, there's also a MX model but has features that we don't (can't) use on motorcycles, worth there weight in gold, it's paid for itself many times over not having to go to a dealership for problems and service aspects. Good luck with your engine light coming on, doesn't sound too bad if after 3 cycles it cancels, had a similar problem with the st when I filled up with fuel right to the top, these things are sent to try us !!!!!

 

The EM warning light has come on several times on my 2017 Street Twin. The first time was on the way home following a service at my Triumph dealer. I took it straight back. They checked it but found nothing wrong (and switched it off). It happened again about a year (2020) later while I was on the 2000+ mile Malle Rally. I didn't want to leave the rally so took the risk and carried on. It went off after a couple of hundred miles. On the last day of the 6 day rally it came on again and coincided with the fuel light, so I had 2 warning lights glowing at me! Again it went off after another few hundred miles. I took it to my dealer who checked it again but still couldn't find a fault.

It has probably happened a couple more times since then. The bike is regularly serviced and there are no unusual noises or power loss. I've sort of grown to live with it.

Incidentally, I've owned cars that have had the EM light flick on but no fault has been found.

 

I carry the OBDLink LX (mentioned above) in my small toolkit. So if I ever got a warning light I can check and reset codes on the road. (I have TuneECU on my phone, but I assume that the OBDLink app would also show codes and allow clearing too).

 

No one has mentioned Dealertool which can read/reset codes and more, similar to Tune ECU I should imagine although I have no experience of that.

 

@David Aldworth
Plug that in under the seat.
Open app on smartphone, mines a Samsung S20 on Android.

Do what you need to do once it's paired.
