MID 109 CAT Fault Code

Integrated Combustion Sensing Module #1

Cause :

If this error lights up and service icons appear on the dashboard, then to remove it, you need to check the operation of the electric motor of the valve lift adjustment mechanism. To reset the code, you must determine the cause of the open loop.This combination is associated with interruptions in the ignition cylinders of the power unit. The cylinder number is not indicated, therefore, the user must independently check each element, including compression.


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.
