Implement ECM 1 (MID 82)
DTC Failure Mode (FMI) Diagnostic Code Procedure
2261 03 Left Desired Grade Offset (Increment/Decrement) Switch / voltage above Normal
04 Left Desired Grade Offset (Increment/Decrement) Switch / voltage below Normal
2262 03 Right Desired Grade Offset (Increment/Decrement) Switch / voltage above Normal
04 Right Desired Grade Offset (Increment/Decrement) Switch / voltage below Normal Code 2261 with FMI 03 or 04 is related to the Left Desired Grade Offset (Increment/decrement) Switch power circuit.Code 2262 with FMI 03 and 04 is related to the Right Desired Grade Offset (Increment/Decrement) Switch power circuit.Note: The System will generate a Level 2 warning when any of the diagnostic codes in the above table with FMI 03 and FMI 04 become active.
Intermittent or damages to the switch wiring circuit.
A component has failed (Switch).
A component has failed (Machine Implement ECM).Note: Failure of ECM is highly unlikely.
Visually check the machine harness from the switch connector to the implement ECM connector, ensure that there is no damages or broken wires. Correct any problem.
Perform contact connections check using an Ohm Meter to the switch pins while it is disconnected from the machine harness and replace it, if it is not working properly. Refer to the Table 13 or the machine schematic for more information.
Disconnect the sensor connector and the machine Implement ECM connector and perform a resistance (Ohm) check of the wires circuit from the Switch Connector to the machine Implements ECM Connector, correct any problem. Refer to the Table 12 and 13 or the machine schematic for more information.
Replace the
