Schematic for the Lift Raise Solenoid
This diagnostic code is recorded when the ECM detects a short to ground in the electrical path from the ECM to the solenoid. The return circuit is connected for all solenoids. The return circuit connects to contacts J1-7 and J2-3 (wire H716-WH(White)) of the implement ECM.The possible causes of this diagnostic code are listed:
The solenoid winding has low impedance or the solenoid winding is shorted.
The signal circuit from the ECM for the solenoid is shorted to ground.System Response:The machine response is listed:
The lift linkage will not raise.
The raise detent coil will be disabled.
The implements will be disabled until the fault is corrected and the levers are centered.Note: The following test procedure may create other diagnostic codes. Ignore the created diagnostic codes. Clear these diagnostic codes when the original diagnostic code is corrected.Note: Ensure that the diagnostic code is active and that the diagnostic code indicator is active.Test Step 1. CHECK THE SOLENOID.
Turn the disconnect switch and the key start switch to the ON position.
Observe the ON/OFF status of the diagnostic code indicator.
Disconnect the solenoid with the diagnostic code from the harness. Expected Result:The diagnostic code indicator remains active.Results:
YES - The diagnostic code indicator remains active. This indicates that a diagnostic code remains active. The harness has failed or the ECM has failed. Proceed to Test Step 2.
NO - The diagnostic code indicator is inactive.Repair: The solenoid valve has failed or the connecting harness has failed. Repeat this test in order to verify the failure. Repair the solenoid or replace the solenoid. Repair the connecting harness or replace the connecting harness at the solenoid.STOPTest Step 2. CHECK FOR A SHORTED HARNESS.
Turn the disconnect switch to the OFF position.
The solenoid valve of the previous test step remains disconnected.
Disconnect the harness from the implement ECM.
At the harness connector for the ECM, measure the resistance between the contacts for the solenoid with the failed circuit (wire H713-PK(Pink)) and contact J1-2 (wire A272-BK(Black)). Expected Result:The resistance is less than 5000 Ohms.Results:
YES - Resistance is less than 5000 Ohms (continuity).Repair: The machine harness has failed. The corresponding solenoid wire is shorted to ground in the harness. Repair the harness or replace the harness.STOP
NO - Resistance is greater than 5000 Ohms (no continuity).Repair: The harness circuit resistance is correct. It is unlikely that the ECM has failed. Exit this test step. Perform the test step for this diagnostic code again. Also, ensure that the diagnostic code indicator is active for this diagnostic code. If the cause is not found, replace the ECM. See Testing and Adjusting, "Electronic Control Module (ECM) - Replace".STOP
