I crashed my Gsxr and it went into a ditch. The fairings are toast, the fuel tank was punctured, stator cover was cracked, kickstand bent, Front left turn signal broke, and does not work, clutch lever broke, master clutch cylinder broke.
I've fixed everything but the lights.
I turn the bike on and put the kickstand up, toggle the killswitch, put it in neutral.
The "CHEC" code is still displaying after all of those steps.
Bike should be able to start in neutral with kick stand down, so I checked that off the list.
I try to start it, and the engine cranks, sounds promising at first, but it just doesn't want to start.
I'm not sure how to get the CHEC code to go away.
Can broken lights cause this? Thought it was the tip sensor, but why would it be showing "CHEC"?
tldr;
Crashed Bike, fixed everything but broken turn signals, "CHEC" code still shows, Bike cranks but does not start.
CHEC means that the cluster isn't getting data from the ECM. Check that the ECM is getting power by looking for 12V at the O/W lead at the dealer mode connector. Also take a look at the diagram on 9-12 of the service manual.
I'd check your wiring closely. Computer isnt communicating with the instrument cluster.
Sounds like a wiring issue from the crash.Also thee's a fair chance chance the ECU is damaged as well, pull it and inspect it visually for starters, especially the back of it.
Just took these. I've done a lot of repairs so it doesn't look nearly as bad as it did the day of the crash. I think it looks kinda pretty now. Can't stop looking at it
Your ECU is most likely not getting any power. You should probe the O/W wire at each stop it makes after it comes out of the engine stop switch (killswitch) on its way to the ECU, to see where power is lost. If you get power everywhere (injectors, coils, fuel pump, etc.) except for the the ECU, you're probably missing a certain jumper on a certain connector meant for the OEM alarm system. Search the forum for more details.
I don't think so. Depending on the model, I've seen it shown in wiring diagrams for E02,19 and 24 country codes, so UK, EU and Australia. My K4 should have it (according to the manual; I dont think I've ever checked) and it doesn't have an immobilizer.
A good way to tell, is by checking that you have an O/G wire in the dealer mode connector, instead of an O/W one.
P.S. You're right about K3/K4. The immobilizer wasn't used until K5 and the E2 & E19 K3/K4 models only had the jumper. In subsequent years the E2, E19, & E24 models had an immobilizer and they also had the jumper while the non-immobilizer models did not.
Update: I've been busy lately and haven't had much time and money to mess with the bike.
I was confused as to why the new ECU didn't work. So I bought another one from a more reliable source, other than Ebay. Still no luck starting it up.
I was doing some more looking around, and I decided to disconnect the fuel pump and the 'CHEC' code went away. I don't know if that means the fuel pump is bad or what?
I'll have to do some more testing when I have some time.
Issue: 'CHEC' is displayed and bike won't start, tries to start but fails, ECU was replaced, Tip over sensor was replaced, kill switch works, all lights work, clutch works.
The guy in this video has the exact same issue as I am having. He said it was a bad fuel pump. So I just purchased one, and I will see if that fixes it.
The guy in the video is an idiot. He has a California model and doesn't recognize the carbon canister. I didn't hear the pump priming when he turned the ignition on.
You seem to be randomly throwing parts at yours. You've now bought two ECM's? It's fairly easy to test the fuel pump to see if it works. The ECM knows when there is power on the Y/R lead to the fuel pump (and the injectors) but that's all it knows about the pump. If CHEC goes away when you disconnect the pump, that sounds more like a wiring harness problem - probably involving the B/W ground. A $20 multimeter would be a lot cheaper than all these parts. As a wild suggestion, try swapping the fuel pump and cooling fan relays to see if anything changes.
Sadly, this is my first bike I've ever owned and this is all a learning experience for me. And I bought an ECU because it was suggested on here. I was told by some friends that are always working on bikes, that the used ECU that I bought was bad, so they said I should buy another because they were certain that was the issue. And I did crash the bike, so I HAD to throw some new parts on it.
Thanks for the response. If this fuel pump doesn't fix things, I'll take a more in depth look at the harness and relays.
Thanks everybody for helping out, I finally replaced the fuel pump on my bike and it is now up and running. Missed riding this thing, it's been way too long.
