Warning Level
The ECM will assign warning level to an active code. The warning level is based on the severity of the abnormal system condition. Each warning level requires a specific response from the operator. The warning levels and required operator response are listed below:Level 1
Warning level one alert the operator that a machine system requires attention. The operator should check the involved system condition or perform maintenance on the involved system at earliest possible time.Level 2
Warning level two requires changing the operation of the machine or preforming maintenance procedure. Failure to correct the problem that causes this warning, may damage the components from the machine system that are involved.Level 2S
Warning level 2S requires an immediate change in machine operation to avoid possible damage to the system of the machine.Level 3
Warning level 3 requires an immediate safe shutdown of the machine to avoid damage to the machine or injury to personal around the machine. Problem that causes the event must be corrected before machine operation can resume.Cat® Grade Control Cross Slope System Codes

There are five different failure mode identifiers related to the cross slope system FMI 2, 3, 4, 9, and 13.FMI 02 - Data erratic, intermittent, or incorrect
The signal from a component is present. The control ECM that reads the diagnostic information cannot read the signal properly. The signal appears to be gone, unstable, or invalid. The data can be correct or incorrect intermittently. Also, this condition relates to communication between ECM controls. This is an example of communication between controls. When the monitoring system is looking for the engine speed from the Engine ECM over the Cat® Data Link. Some of the conditions that cause the FMI 02 diagnostic code to be activated are:
There is a poor
