18 V-MAC Co-Pilot Operator's Manual Shutdown Warning Indicator The Shutdown Warning indicator, red in color, illuminates if the Engine Coolant Level (ECL) is below the minimum level allowed, the Engine Oil Pressure (EOL) is below the minimum allowed, the Engine Coolant Temperature (ECT) or aftertreatment Diesel Particulate Filter (DPF) soot level trigger are above the maximum allowed. Some vehicles also have optional shutdown functions available when the transmission temperature or engine Exhaust Gas Temperatures (EGT) are above maximum allowable limits. During a shutdown event, V-MAC IV also provides an audible alarm.
The alarm will also sound and the red shutdown indicator will turn on when V-MAC IV detects a problem or excessive periods of idling. Shutting the engine down is warranted. The shutdown warning indicator is usually located on the left-hand side on the dash cluster. W3036501 Engine Shutdown Warning Indicator (Red) V-MAC IV can be programmed to actually shut down the engine if conditions warrant (low coolant, low EOL, high Engine Oil Temperature (EOT), high ECT, high engine EGT or high automatic transmission oil temperature if so equipped). Shutdown is mandatory for Crankcase Pressure (CCP).
With this option enabled, the engine will automatically shut down within approximately 30 seconds after the red SHUTDOWN indicator turns on and the alarm activates (provided the vehicle is not moving above the road speed threshold).
