C8.3 Industrial Electronic Controlled Fuel System Section 1 - Operating Instructions Page 1-13 If the STOP or CHECK ENG lamp comes on when the engine is running, it means a fault code has been recorded. The lamp will remain on as long as the fault exists. The severity of the fault will determine which lamp is illuminated. Diagnostic Fault Codes Stop Engine Lamp The STOP ENGINE lamp is a red lamp. This lamp indicates that the engine needs to be shut down before permanent damage occurs to the engine. NOTE: The engine must be shut off as soon as it can be shut off safely. The engine must not be run until the fault is corrected.
This lamp is also used to flash out the fault code number in the diagnostics mode. Check Engine Lamp The CHECK ENGINE lamp comes on during a nonfatal system error. The engine can still be run, but the fault must be corrected as soon as possible. NOTE: In the diagnostics mode, the CHECK ENGINE lamp completes the three-digit fault code. Engine Maintenance Lamp The ENGINE MAINT lamp comes on when engine maintenance is required. Wait to Start Lamp The WAIT TO START lamp is only used on engines with an intake air heater system such as C Series engines.
