Anyone have any idea what this code is for on a L4701 or what to check to remedy it? Called dealer but no response yet. TIA
Fault code u0081
- Thread starter jredkins
- Start date
CAN 1 frame error. From the sound of things something may have happened when you went to start it? Check ignition wiring and fuses?
Ever figure this one out? I’m getting codes U0081, U0082, and U0083 after replacing a blown ECU fuse. Fuse kept blowing and shutting the tractor down as I limped it home to the garage. This is on my MX5800
I can’t help on the codes, but I‘d like to make a suggestion regarding fuse replacements:
Fuses are for the purpose of protecting the WIRE ...not the component. If a component fails...or if a wire “shorts”... a large increase in current can occur which may melt insulation and start a FIRE. Things got HOT .... so that fuse “blew” to protect your equipment.
(When a fuse “blows” it’s because there was a current over-load and the fuse acts as a safety-valve to prevent further damage to the component and/or damage to the wiring harness.)
When the fuse is replaced, the current is restored to the circuit... Usually the operator is HOPEFUL that the problem was a defective fuse or a transient problem.... BUT....if the fault was not corrected the fuse should “blow” again. EACH TIME the operator replaces that blown fuse the current is restored and the component AND WIRE SUFFERS another potential OVERHEAT which may eventually lead to permanent damage. Short answer: replacing a blown-fuse risks further damage. A good replacement fuse WILL DO IT’S JOB and “blow” again if the defect still exists.
A good practice is: If a fuse blows... inspect for obvious damage that may have caused the current OVERLOAD. If none can be found, then replacing the fuse ONE TIME is probably safe. But multiple replacements of a fuse that blows is a good way to create more damage than the original fault and/or actually watch your machine burn up before your eyes. No exaggeration. No kidding.

Most of us do. But some people replace a fuse again and again and again and..... because they DON’T know the hazards. Just wanted to help those who haven’t thought about that side of things.
it's a communication error in the can line
there is a bulletin that addresses the proper way to diagnose it
it can be a ton of things from ecu failure to ecu corrosion wiring problems etc
