Test 12B - 2-4 Pressure Switch Sense Circuit
NOTE:
Perform TEST 12A
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 Transmission Control Module (TCM) connector. DO NOT disconnect jumper wire previously installed in TEST 12A . Use scan tool in voltmeter mode. On F24S and FJ22 models, measure voltage at terminal No. 7 of TCM connector. On all other models, measure voltage at terminal No. 47 of TCM connector. On all models, if voltage is more than 10 volts, replace TCM. If voltage is 10 volts or less, repair open 2-4 pressure switch sense circuit.
