I have searched high and low and have been unable to find a post that covers the issue I am having.
2007 GRiSO 1100. Potential pertinent Mods:GuzziTech ECU reflash, GuzziTech exhaust system, BMC filter, PC-V with Auto Tune, LED turn signals with resistors and LED headlight. All mods have been on the bike for some time without issue.
Put in new Battery Tender Lithium battery about 4 months ago. Will hook up Battery Tender Lithium specific charger at least every 3-4 weeks if bike isn't being ridden to maintain charge. Put the bike on the charger 2 days ago as I knew I would be riding the bike today (scheduled to be used in a music video shoot). Went to start the bike this morning and the battery was dead. Checked voltage with a meter and it was completely dead. Assumed I got a bad battery for it to die that quickly. Went and bought a new AGM battery. Once the new battery was installed, and I turned the ignition on, I got a small service wrench at the top of the dash with LD04HZ displayed across the dash. This message stays on the dash when the ignition is turned off and the key is removed. I cannot find this error code listed anywhere.
The bike will start and run (and runs as normal), but the dash no longer functions at all - other than displaying the error message. I have also lost the headlight (but the flash to pass still functions) and lost the turn signals. The horn still functions. Tail light and brake light are normal. I checked all fuses, and unless there are some hidden ones I don't know about, are fuses are intact.
Does anyone know what is going on?
