CAUTION Use care when testing electrical connectors not to bend connector pins or damage connector sockets with multimeter probes. Failure to comply may result in damage to equipment. RESISTANCE TEST (8) Connect negative (-) probe of multimeter to ground and note reading on multimeter. 14° to 32°F (-10° to 0°C) 32° to 50°F (0° to 10°C) -4° to 14°F (-20° to -10°C) 50° to 68°F (10° to 20°C) 68° to 86°F (20° to 30°C) 86° to 104°F (30° to 40°C) 104° to 122°F (40° to 50°C) 122° to 140°F (50° to 60°C) 691-754 ohms 754-820 ohms 820-889 ohms 889-962 ohms 962-1039 ohms 1039-1118 ohms 1118-1202 ohms 1202-1286 ohms Change 1 2-1515 (1) Set multimeter to ohms. (2) Connect positive (+) probe of multimeter to connector P119a. NOTE Transmission sump oil temperature sensor resistance reading is affected by temperature. Refer to Table 2-32. Transmission Sump Oil Temperature Sensor Resistance Readings for details. (3) Connect negative (-) probe of multimeter to connector P119d and note reading on multimeter. (4) Connect negative (-) probe of multimeter to all other pins in connector P119, one at a time, and note reading on multimeter. (5) Connect negative (-) probe of multimeter to ground and note reading on multimeter. (6) Connect positive (+) probe of multimeter to connector P119d. (7) Connect negative (-) probe of multimeter to all other pins in connector P119 (except P119a), one at a time, and note reading on multimeter. (9) If correct resistance is not present in step 3, or continuity is present in step 4, 5, 7, or 8, notify DS Maintenance. (10) If correct resistance is present in step 3 and continuity is not present in step 4, 5, 7, or 8, replace WTEC III transmission ECU (para 8-7). (11) Connect connector P119 to connector J119. (12) Position front grille on cab with washer and screw. (13) Position two washers and screws in front grille. (14) Tighten screw to 48-60 lb-in. (5-7 N·m). (15) Tighten two screws to 24 lb-in. (3 N·m). (16) Clear diagnostic codes (para 8-5). Temperature Table 2-32. Transmission Sump Oil Temperature Sensor Resistance Readings Resistance TM 9-2320-365-20-2
