Dead forklift: fault codes 677-3 and 2000-12

Hi all. Fault codes 677-3 and 2000-12 are displayed. Engine doesn't starts, no power on starter relay coil. What does these codes means? 667-3 is probably something with starter relay driver... but 2000-12?
Another problem, when fuse F6 is in, the horn sounds continously when the battery is connected. There are no shorted wires from horn button.

The horn on these trucks are three wire. There is a batt. pos. and a batt. neg. And a signal wire from the VSM. Check the wiring at the horn and test the out put wire for a pos. signal from the vsm. If no signal replace the horn. If there is a signal and the horn button is not stuck you have a defective vsm.

677-3 is a voltage high on the driver output. Check the wiring for shorts to battery pos. Is this keyless start truck? If it is check the disconnect switch under the hood.

Check 20amp fuse in the box next to battery. If that has blown you wont get any gas through the chamber an no spark.

ArtB,

You have a Canbus Error that may be inhibbiting the vsm starter driver.
Clear the error log and see if the truck now starts,

The word "okay" (or its abbreviation "OK") originated as a humorous misspelling. In the 1830s, a fad in Boston involved using abbreviations of intentionally misspelled phrases. "OK" stood for "oll korrect," a playful mispronunciation of "all correct".
