When using the Electronic Control Analyzer Programmer (ECAP) tool, an active diagnostic fault code (111-01) for coolant level may be logged. This fault code is an error because the current 3412 Generator Set Engine does not have a coolant level sensor.
The 126-9481 Wire Assembly is now available to correct the fault. When the wire assembly is inserted into the engine's wiring harness in the P7 connector, it shorts out the coolant level sensor input (C) to analog ground (B). The serviceable parts of the plug are shown in the following illustration.
