Error code 01?
« on: May 13, 2021, 02:53:17 pm »
Hi,

When I started my yamaha bolt rSpec 2014 today I got error code 01. The bike started and seems to be idling as usual. I didnt go for a ride since I wasnt sure what the error code means. Seems like it has something to do with the ecu signal?

So far I have checked the battery, the fuses, disconnected the ecu and the battery and reconnected all but error code still shows up. I also tried the ecu from another Bolt but same error.

Any help would be appreciated!

Cheers

Niclas from Sweden

There is a discussioni this forum on error code 1:  I believe it has to do with the ECU's inability to communicate with the speedometer display, and may indicate a loose connection somewhere.

See the attached figure for trouble shooting ECU Error Code ER1:

Checking your battery -- open circuit battery should read 12.8 volts.  If it reads 12.7 or less, it needs charging.  If it reads less than 12 volts, replace the battery.  A low battery can cause many strange things to happen that go away when the battery is fully charged or replaced.

Checking Circuit breaker fuses - check with a continuity or ohm meter.  Sometimes a faulty fuse is not visibly apparent.

Checking electrical continuity in wiring harness -- very hard to find sometimes.  Also look for any corrosion on connection points on wire or pins, as well as bent or misaligned pins.

Last ditch effort -- take the bike to a dealer for diagnostics and repairs.
