1.1. Introduction¶
1.2. Purpose¶
This document is the troubleshoot information for the AGCO POWER EEM4 Electronic Engine Management system. The provided fault descriptions include information on the possible causes for the fault, on the influence on the engine operation and instructions to resolve the problem.
1.3. Scope¶
The system reports detected faults by fault codes. These fault codes can be read over the CAN bus from the EEM4 controller using a WinEEM Service Tool. The fault codes may also be transmitted over the CAN bus to a vehicle’s instrument panel. Alternatively, the fault codes can be shown using blink codes on a diagnostic lamp.
When a fault code is known, the enclosed documentation can be used to analyze the reason for the fault and to find a solution to the problem. Additional equipment may be needed to inspect the system components and Their operation (e.g. multimeter).
