Hoist Raise solenoid circuit
This diagnostic code indicates the "Chassis" ECM detects the hoist raise solenoid voltage is above normal.This diagnostic code can be caused by:
Solenoid failure
Solenoid energizer circuit shorted to the +battery circuit.
ECM failureNote: The following test procedure may create other diagnostic codes. Ignore these created codes and clear these created codes after the original diagnostic code has been corrected. Ensure diagnostic code CID 0724 FMI 03 is active before performing this procedure.Note: Use a calibrated digital multimeter for this procedure.Test Step 1. CHECK FOR A SHORT TO +BATTERY
Turn off the key switch and the disconnect switch.
Disconnect the harness from the solenoid and the ECM.
At the harness connector for the ECM, measure the resistance from contact J1-62 (wire F918-WH(White)) to all contacts used in the harness connectors for the ECM.Expected Result:Each resistance is greater than 5000 ohms.Results:
OK - Each resistance is greater than 5000 ohms. Proceed to Test Step 2.
NOT OK - A resistance is less than 5000 ohms. There is a short between contact J1-62 (wire F918-WH(White)) and the circuit low resistance.Repair: Repair or replace the harness.STOPTest Step 2. CHECK THE DIAGNOSTIC CODEThe key switch and the disconnect switch remain in the off position.
Inspect the harness.Clean the harness connector contacts.Inspect the harness connector contacts for corrosion or damage.Inspect the wire insulation for damage caused by heat, corrosion, or chafing.
Perform a 45 N (10 lb) pull test on each circuit wire.
Reconnect all harness connectors.Verify that the connectors are fully seated and the clips are fastened.
Check for intermittent problems. Using Cat® Electronic Technician (Cat® ET), perform a wiggle test on the harness.
Turn on the disconnect switch and the key switch.
Operate the machine.
Check the CID 0724 FMI 03 status.Expected Result:CID 0724 FMI 03 is not active.Results:
OK - CID 0724 FMI 03 is not active.Repair: The initial diagnostic code was probably caused by a poor connection at one of the connectors that was checked.Resume normal operation.STOP
NOT OK - CID 0724 FMI 03 is not active. The ECM may have failed.Repair: Exit this procedure and perform this procedure again. Contact your technical communicator. If the ECM requires replacement, see Testing and Adjusting, "Electronic Control Module (ECM) - Replace".STOP
