FMI 2034 CAT Fault Code
Attachment #3 Rod End to Tank Spool Not Responding to Command
Cause :
Malfunction in the thermostat control system. The on-board computer reports problems with communication with the control unit, so a possible cause may be poor contact. The cooling system circuit is open, which may affect the operation of the power unit as a whole.The most common mistake when addressing this code is replacing the starter or PCM when the damage is in the wiring or other components. Thus, it's extremely important to conduct a thorough diagnosis before replacing anything to avoid unnecessary replacements of parts.
Don't forget ! When a fault code pops up, CAT's Uptime Center is automatically notified via an cellular link, and it alerts the truck's owner by prearranged methods, usually email or phone calls.
