CAUTION Use care when testing electrical connectors. Do not damage connector pins or sockets with multimeter probes. Failure to comply may result in damage to equipment. NOTE Inspect connector pins/sockets for damage, corrosion, and serviceability. Check that connector pins are not pushed back and are capable of making good contact. RESISTANCE TEST NOTE (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 8-4). (1) Set multimeter to ohms. (2) Connect positive (+) probe of multimeter on P119a. Change 1 2-1619 TM 9-2320-366-20-2 Transmission sump oil temperature sensor resistance reading is affected by temperature. Refer to Table 2-19. Transmission Sump Oil Temperature Sensor Resistance Readings for details. (3) Connect negative (-) prove of multimeter on 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. (8) Connect negative (-) probe of multimeter to ground 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 II TEPSS (para 8-2). Table 2-19.
