TM2361 (24JUN08) 9001-50-11 450DLC Excavator Operation and Tests 062608 PN=211 Monitor Controller (MON) Diagnostic Trouble Codes 13310.02 — Shorted circuit in Coolant Temperature Sensor MS12501,0000041 –19–26MAY06–1/1 9001 50 11 Coolant Temperature Sensor Diagnostics Short circuit in coolant temperature sensor circuit. – – –1/1 1 Coolant Temperature Sensor Resistance Check Disconnect coolant temperature sensor and check resistance. Engine Coolant Temperature Resistance (k[OHgr ]) 25°C 7.6 77°F 40°C 3.65—4.35 104°F 50°C 2.48—2.92 122°F 80°C 0.98 176°F 95°C 0.60 203°F 105°C 0.45 221°F 120°C 0.30 248°F Is resistance within specification? YES: Go to Harness Check. NO:
Coolant temperature sensor malfunction. Replace sensor. – – –1/1 Engine Coolant Temperature Resistance (k[OHgr ]) 25°C 77°F 7.6 40°C 104°F 3.65—4.35 50°C 122°F 2.48—2.92 80°C 176°F 0.98 95°C 203°F 0.60 105°C 221°F 0.45 120°C 248°F 0.30 2 Harness Check Check harness between coolant temperature sensor and monitor pin C8 for short. Is there a short to ground or short to power in harness? YES: Repair or replace harness. See Cab Harness (W1) Wiring Diagram, see Machine Harness (W2) Wiring Diagram, see Monitor Harness (W3) Wiring Diagram, and see Engine Harness (W4) Wiring Diagram. (Group 9015-10.) NO: Monitor controller malfunction. Replace controller. See Monitor Controller Remove and Install.
