Hoist Control Valve
(1) Solenoid Valve (Hoist Enable).
The location for the Solenoid Valve (Hoist Enable) is under the chassis between the transmission and the torque converter.
Illustration 2 g02538337
Schematic Of The Solenoid Valve (Hoist Enable)
Note: The approximate coil resistance of the solenoid is 41 ohms at 25 °C (77.0 °F).This diagnostic code is associated with the Solenoid Valve (Hoist Enable). The FMI 06 means that the ECM has determined that the current of the solenoid is above normal.The possible causes of this diagnostic code are listed:
The energize circuit of the solenoid is shorted to ground.
The solenoid has failed.
The ECM has failed. This situation 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 1243 FMI 06 is active before performing this procedure.Note: Use a calibrated 146-4080 Digital Multimeter for the measurements in this procedure.System Response:The ECM will turn off the solenoid for the hoist pilot system enable. This will cause the hoist system to be forced to the HOLD mode.After the diagnostic goes away, the ECM will continue to command the system to be in the HOLD mode until the hoist lever is moved into the HOLD mode.Test Step 1. CHECK THE SOLENOID.
Turn the disconnect switch and the key start switch to the ON position. Do not start the engine.
Observe the status of the diagnostic code.
Disconnect the solenoid with the active diagnostic code from the machine harness.Expected Result:CID 1243 FMI 06 changes to CID 1243 FMI 05 when the solenoid is disconnected.Results:
YES - CID 1243 FMI 06 changes to CID 1243 FMI 05 when the solenoid is disconnected. The circuit is correct.Repair: The solenoid has failed. Repeat this test "CHECK THE SOLENOID" to verify the solenoid failure. Replace the solenoid.STOP
NO - CID 1243 FMI 06 remains active. Proceed to Test Step 2.Test Step 2. CHECK THE ENERGIZE CIRCUIT OF THE SOLENOID FOR A SHORT TO GROUND.
Turn the key start switch and the disconnect switch to the OFF position.
The solenoid remains disconnected from the machine harness.
Disconnect the machine harness connectors from the ECM.
At the machine harness connector, measure the resistance from the signal contact J1-66 (wire J826-PK(Pink)) to all contacts that are used in the machine harness connectors for the ECM.Expected Result:Each resistance measurement is greater than 5000 ohms.Results:
OK - Each resistance measurement is greater than 5000 ohms. The machine harness is correct. Proceed to Test Step 3.
NOT OK - Each resistance measurement is not greater than 5000 ohms. There is a short in the machine harness. The short is between J1-66 (wire J826-PK(Pink)) and the circuit with the low-resistance measurement.Repair: Repair the machine harness or replace the machine harness.STOPTest Step 3. CHECK IF THE DIAGNOSTIC CODE REMAINS.
Inspect the harness connectors and clean the contacts of the harness connectors.
Reconnect all harness connectors.
Turn the disconnect switch and the key start switch to the ON position.
Operate the machine.
Check the status of the CID 1243 FMI 06.Expected
