Main Controller (MCF) Diagnostic Trouble Codes 11405.04 Travel Speed Solenoid (SI) Valve Current Feedback Low MS12501,000005D –19–14JAN06–1/1 Travel Speed Solenoid (SI) Diagnostics Travel speed solenoid (SI) current 56 mA or less. –1/1 TM2361 (24JUN08) 9001-10-43 450DLC Excavator Operation and Tests 062608 PN=67 3 Solenoid Function Check Switch travel speed solenoid (SI) harness connector with another solenoid valve in solenoid valve manifold. Clear diagnostic trouble codes (DTC) and re-check for DTC. Does diagnostic trouble code stay with travel speed solenoid (SI)? YES: Travel speed solenoid (SI) malfunction. Replace solenoid. NO: Main controller (MCF) malfunction. Replace controller.
See Main Controller (MCF) Remove and Install. (Group 9015-20.) – – –1/1 9001 10 43 1 Solenoid Resistance Check Disconnect harness connector from travel speed solenoid (SI). Check resistance of solenoid. Is resistance between 14.8—22.2 ohms? YES: Go to Continuity Check. NO: Travel speed solenoid (SI) malfunction. Replace solenoid. – – –1/1 2 Continuity Check Disconnect harness connectors from main controller (MCF) and travel speed solenoid (SI). Check for continuity between main controller (MCF) connector A pin A11 and travel speed solenoid (SI) harness connector pin 1.
Check for continuity between main controller (MCF) connector A pin A17 and travel speed solenoid (SI) 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.
