ENGINE ELECTRONIC CONTROL UNIT
John Deere Engine Electronic Control Unit
The John Deere Electronic Control Unit (ECU) is capable of detecting, storing, and reacting to abnormal engine operating conditions or faults. The presence of a fault is reported to the operator through the amber colored lamp (A) located on the dash. Depending upon the severity of the engine fault detected, the ECU may take steps to minimize engine damage by reducing power output. Faults are also stored in the ECU and can be accessed by service personnel later. These stored faults can be viewed using the same amber colored lamp (A) located on the machine's dash using a system known as Blink Code Diagnostics. Details and procedures regarding ECU fault detection, engine protection, and blink code diagnostics are outlined below.
Engine Protection
When the engine is in operation, and the engine ECU detects a Warning Condition the amber light (A) on the dash will begin flashing. A Warning Condition is an engine fault in which a critical monitored engine parameter goes beyond normal operating values. If the engine operating conditions are not improved, or become more extreme, the Warning Fault may become a Shutdown Fault. At this point, the amber light (A) on the dash will stay lit and the engine ECU may begin a sequence of power reduction. The operator is responsible for shutting down the engine to prevent further damage to the engine.
The engine ECU will not detect all engine problems. The engine protection feature is not a substitute for routine engine maintenance. Normal machinery operating procedures should be adhered to.
