Test 37A - Transmission Range Sensor (TRS) T41 Sense Circuit
NOTE:
Perform TEST 5A
before proceeding with this test. For connector terminal identification, see CONNECTOR IDENTIFICATION
. For wiring diagrams, see WIRING DIAGRAMS
. Perform VERIFICATION TEST VER-1A
after each repair.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Disconnect TRS connector. Turn ignition on. Use scan tool in voltmeter mode. Measure voltage at terminal No. 10 on TRS connector. If voltage is 10 volts or less, go to next step. If voltage is more than 10 volts, replace TRS.
- Turn ignition off. Disconnect Transmission Control Module (TCM) connector. On F24S and FJ22 models, inspect terminal No. 1 on TCM connector. Clean and repair as needed. On all other models, inspect terminal No. 41 on TCM connector. Clean and repair as needed.
- Use scan tool in ohmmeter mode. On F24S and FJ22 models, measure resistance at terminal No. 1 on TCM connector. On all other models, measure resistance at terminal No. 41 on TCM connector. On all models, if resistance is 5 ohms or less, repair T41 sense circuit for short to ground. If resistance is more than 5 ohms, replace TCM.
