TM2361 (24JUN08) 9001-10-37 450DLC Excavator Operation and Tests 062608 PN=61 Main Controller (MCF) Diagnostic Trouble Codes 11400.04 — Pump 2 (5-Spool) Control Solenoid Valve Feedback Current Low MS12501,0000057 –19–21FEB06–1/1 9001 10 37 Pump 2 (5-Spool) Control Solenoid Diagnostics Pump 2 (5-spool) control solenoid current 56 mA or less. – – –1/1 1 Solenoid Resistance Check Disconnect harness connector from pump 2 (5-spool) control solenoid. Check resistance of solenoid. Is resistance between 14—21 ohms? YES: Go to Continuity Check. NO: Pump 2 (5-spool) control solenoid malfunction. Replace solenoid.
– – –1/1 2 Continuity Check Disconnect harness connectors from main controller (MCF) and pump 2 (5-spool) control solenoid. Check for continuity between main controller (MCF) connector A pin A30 and pump 2 (5-spool) control solenoid harness connector pin 1. Check for continuity between main controller (MCF) connector A pin A19 and pump 2 (5-spool) control solenoid harness connector pin 2. Is there continuity between the pins? YES: Go to Solenoid Function Check. NO: Open circuit in harness. Repair or replace harness. See Cab Harness (W1) Wiring Diagram, see Machine Harness (W2) Wiring Diagram, and see Pump Harness (W8) Wiring Diagram. (Group 9015-10.) – – –1/1
