TM2361 (24JUN08) 9001-50-12 450DLC Excavator Operation and Tests 062608 PN=212 Monitor Controller (MON) Diagnostic Trouble Codes 13311.02 — Shorted circuit in Fuel Level Sensor 9001 50 12 MS12501,0000042 –19–26MAY06–1/1 Fuel Level Sensor Diagnostics Fuel Level Sensor Shorted to Ground. – – –1/1 1 Resistance Check Disconnect fuel level sensor and check sensor resistance. Is sensor resistance within specifications? Fuel Level Sensor Float Position Resistance (Ohms) Upper Limit (FULL) 6-10 3 / 4 26 1 / 2 33-43 1 / 4 53 Alarm Level 82-88 Lower Limit (EMPTY) 90-100 YES: Go to Short to Ground Check NO: Fuel level sensor malfunction. Replace sensor.
– – –1/1 Fuel Level Sensor Float Position Resistance (Ohms) Upper Limit (FULL) 6-10 3 / 4 26 1 / 2 33-43 1 / 4 53 Alarm Level 82-88 Lower Limit (EMPTY) 90-100 2 Short to Ground Check Disconnect fuel level sensor and monitor from harness and check for continuity to machine ground. Is there continuity between harness and machine ground? YES: Short circuit in harness between monitor controller and sensor. Repair or replace harness. See Cab Harness (W1) Wiring Diagram, see Machine Harness (W2) Wiring Diagram, and see Monitor Harness (W3) Wiring Diagram. (Group 9015-10.) NO: Go to Continuity Check. – – –1/1
