##SOLVED## - Help with GSXR 1000 K5 'CHEC' code
Hi Guys,
My bike has recently come up with the dreaded 'CHEC' code on the console, any advice would be appreciated. It's done it before a couple of times but would randomly come good by itself or as I was trying to trace the error through the wiring harness, but alas this time no luck.
Symptoms:
Bike key turned on, lights on, console displays "CHEC", fuel pump doesn't prime. -similar to when the kill switch it on.
Have flicked the kill switch a few times but no change, am going to open it up and hit it som contact cleaner/put the multimeter across it this arvo, also going to put the bike in dealer mode this arvo and see if any helpful error code pops up (hasn't the last time it did this).
If anybody has a stock working ECU/ECM for this bike they want to sell cheap or lend (30 mins use, tops) so I can quickly check if the issue is with my ECU that would be a huge boon, but I'm rural NSW (Dubbo) so I'm thinking my chances are slim.
If it does turn out to be a bad ECU, any recommendations on an upgrade?

This has been solved for me for a year now so it looks like I found the root of my problem.
The issue reoccurred after replacing the flasher relay but I was able to find the bottom of the issue. I will post it here as I've had pm's asking for assistance...better to put the information somewhere handy rather than keep it to myself.
Under the pillion seat you can find the wiring loom running to the rear lights. There is a capped off connector on the wiring harness (they just end in small cube shaped white cap) near where the tail lights plug in. This cap has a test point in the top of it (I assume it is a test point, it has a small hole in the plastic that you can put the probe from a multimeter on) and when you bumped it with the bike running it would cut out and throw the CHEC error. Give it a wiggle and the fuel pump would prime and you could start the bike like normal. Basically, it was a loose connection and the circuit kept breaking depending on vibration or temperature... anyway my fix was some contact cleaner on the point to git rid of the little bit of corrosion that had built up and then "adjusting" the connectors in the socket to be tighter. Haven't had a problem since. Here are some full size photos of under my pillion seat, I've put simple notes on them and I hope they help anyone who would be scared or otherwise of fiddling with their wiring.
