Connections of the Hydrostatic Pump Solenoid #2This diagnostic code is associated with the hydrostatic pump solenoid #2. The FMI 05 means that the transmission ECM has determined that the current of the solenoid is below normal. The possible causes of this diagnostic code are listed below:
The solenoid has failed.
There is an open circuit or the coil resistance is too high.
The ECM has failed. The ECM failing is unlikely.Note: The following test procedure may create other diagnostic codes. Ignore these created diagnostic codes and clear these diagnostic codes when the original diagnostic code has been corrected. Ensure that the diagnostic code of CID 1762 FMI 05 is active before performing this procedure.Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.System Response:When this diagnostic code is active, the ECM will turn off the current to the failed solenoid.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 pump control B solenoid.
At the machine harness connector for the solenoid, place a jumper wire from connector contact 1 (wire A769-GY) to connector contact 2 (wire H801-PU).
Observe the status of the CID 1762 FMI 05.Expected Result:The CID 1762
