FMI 551 CAT Fault Code
Circle Sideshift Control Out Of Neutral At Inappropriate Time
Cause :
The literal translation of the error is low circuit of the solenoid valve of the intake device located in the second bank. It is necessary to check the operation of the mechanism.If serial data communication is lost between any of the LIN devices on the LIN bus network, the master control module will set a no communication code against the non-communicating LIN device. The Diagnostic Trouble Code (DTC) sets when a supervised periodic message that includes the transmitter device availability has not been received.
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.
