Schematic of the Pitch Solenoid (S/N: AAFAKT7PZ)This diagnostic code is recorded when the ECM reads the current of the solenoid as being above normal.The possible causes are listed:
A wire is shorted to ground.
The solenoid has failed.
The ECM has failed. This is unlikely.System Response:The machine response is listed:
All of the pitch functions of the blade are lost.Note: Ensure that CID 0884 FMI 06 for the solenoid is active. Note: The following procedure can create numerous related diagnostic codes. When all harnesses are reconnected, the related diagnostic codes will be shown as being not active. Clear all related diagnostic codes after this procedure is completed.Test Step 1. CHECK THE SOLENOID.
Turn the disconnect switch and the key start switch to the ON position. Do not start the engine.
Disconnect the machine harness from the solenoid.
At the machine harness connector for the solenoid, install a jumper wire from wire (M930-PK) to wire (H801-PU).
Observe the status of the diagnostic code.Expected Result:
