CRF250L ABS and Engine lights
« on: December 31, 2018, 02:22:46 pm »
2017 model
Currently on 3200km
Went for a short ride yesterday. 40km from home the ABS light started flashing. I stopped, switched off the rear ABS and resumed slowly with the light still flashing. 4km further on the engine light came on, the bike lost power and as I decelerated died.
Hereafter the bike would not start. Stuckk next to the road I contemplated for a bit who I should phone for help. Male pride got the better of me and after a poor visual inspection of all the visible bits (no leaking fluids, mangled metal or loose wiring etc.)I decided to try again. The bike fired up first time. The engine light remained on but the flashing ABS light was off and remained off all the way home at my very sedate pace. Back in town I stopped at a spaza shop to prep for the intensive maintenance I could envision myself undertaking the rest of the afternoon. Starting the engine all previous warning lights are now off. Just as it should be.
Back home I strip the plastic bits, have a look at the metal bits, have a look at the wiring bits, have a look at the battery bits and do a bit of (not useful for this predicament) introspection. Back on goes the plastic bits, all the while the warning indicating bits stay off.
Maintenance done it is time for a test ride. Back on comes my personal protective bits and off we go. No problems on the first 10 km of tarmac. I am able to release all 17 wild galloping ponies and reach 135km/h for the second time since purchasing the steed. Into a bit of sandy tweespoor parallel to the main road and 1km later the ABS light starts flashing. Oh dear!  Shortly thereafter the solid unblinking stern and "I'm so disappointed in you" engine light joins Mama ABS. Straight line home selected and 4km later she dies for a second time that day. Having experience now of what to do in such a situation, I switch everything off, walk to the nearest tree, walk back, get on and ride home with the stare of the unflinching engine light my sole companion.
Back home I try listening to Dr. Forum and can't find my specific set of problems but I do stumble across some annecdotal evidence that the blinking ABS light is a fault code. Now if only I knew that I could have noted the sequence!
I decide to park her for the night and on my morning commute, hopefully the fault returns and I can start deciphering this strange and unholy language. This morning the engine light stayed on from the first start, 500m into the commute the ABS light started flashing. 200m later the engine overheating light made a brief appearance to add its 2c worth of told you so. Turn around, park bike, get cage and get to work.
This is a very long-winded failure report - sorry!
Anyone else ever experience similar sequence/problem?
BTW, the flashing ABS light is probably not a fault code in this instance. It just flashes on and off like a regular indicator light.

I would start by checking battery voltage and connections, can cause all sorts of headaches on new bike. What happens if you pull the abs fuse ?

As said above and disconnect, inspect and reconnect connectors. Especially the ones around the main computer. Sounds like an intermittent fault which is usually electical.

I have no Idea whats wrong although I will always suspect water when it comes to electronic issues.

Have you pressure washed your bike or has it been exposed to a lot of water recently?

I did read recently on the w about a guy having intermittent problems after bike service and it was pressure washed. (Honda NC dct)
I will never bring a pressure washer near my bike but unfortunately some service centres do and I always instruct them on the job-card not to wash my bike since I always bring my bike clean as for in spotless clean.

Pressure washers ruin electronics, bearings and other parts. Sounds like you have already opened and cleaned all connectors so maybe my concern is irrelevant but with the low km's you probably still have guarantee so rather take it back to the dealer for fault finding. Maybe just a regulator

I'm guessing your bike is out of warranty....else you have the obvious answer.

- Like Sidetrack said, check your battery connections. Bad earth can cause lots of kak.
- Then start your bike, and start gently tugging on wires at the connections and junctions to see if you can induce the issue manually. Maybe that can isolate where the problem is.

It seams a little bit too coincidental that the ABS comes on just before the engine light. See if you can bypass the ABS somehow (google it).

I hope you get your issue sorted.   :thumleft:

The positive terminal was "vinger vas" but when I took a screwdriver to remove the battery it was quite loose. There was some visible arc damage to the terminal and connector. I cleaned it up with some sandpaper and properly tightened the terminals. Tested the batteries no load voltage - 13,2V. Load voltage = 12,4V. Alternator's charging voltage = 14V. Short commute to work this morning (9km) went without incident, but I'm still a bit "skrikkerig" to venture too far from home. Will continue to take short trips around town until I'm confident that that was indeed the problem. Hopefully it's sorted now!

Thanks for all the replies.
