Should there be a fault between the ECM and the CMS, the following can be observed on the CMS display:
- The oil pressure gauge (1) will flash.
- The coolant temperature gauge (2) will flash.
- The tachometer (7) will flash and a digital reading of 3000 RPM will be displayed.
- The coolant level indicator (6) will flash.

| Engine Oil Pressure (1) - Indicates the oil pressure in the engine. GREEN RANGE is the normal operating pressure. RED RANGE is low oil pressure. |
Show/hide table
| Engine Coolant Temperature (2) - Indicates the temperature of the engine coolant. GREEN RANGE is the normal operating temperature. RED RANGE is excessive engine coolant temperature. |

Tachometer (7) - The tachometer displays the engine rpm in a digital read-out during operation.
Speedometer (8) - The speedometer displays the machine ground speed in a gauge display during operation.
Actual Gear Indicator (9) - The actual gear indicator consists of two digits. The two digits indicate the actual transmission gear that is engaged. The left digit is the actual gear. The right digit shows the direction that was selected.
Service Code (10) - During machine operation, if this indicator comes on, the CMS control has detected and stored information regarding abnormal electrical conditions in CMS circuits (inputs or outputs) or in a power train control circuit.
Diagnostic information is available in the service mode for service personnel.
Reference: For more information, refer to Systems Operation, Testing and Adjusting, "Computerized Monitoring System with Vacuum Fluorescent Display" for the machine that is being serviced.
Reference: For information on transmission control faults, refer to the Systems Operation, Testing and Adjusting, "Electronic Transmission Control System" for the machine that is being serviced.

Loss of brake oil pressure may decrease the brake application force. Also, loss of brake oil pressure may cause the parking brake to engage. If low brake oil pressure is indicated, stop the machine immediately. Inspect the system for the cause of low brake oil pressure. Repair the brake system before returning the machine to operation. |
