Test 7A - Relay Output Always On (DTC 14)

NOTE: Perform TEST 1A  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.
  1. Disconnect transmission control relay. Turn ignition on. Using scan tool, read SWITCHED BATTERY voltage. If voltage is more than 3 volts, go to TEST 7B  . If voltage is 3 volts or less, go to next step.
  2. Disconnect transmission solenoid pack. Using scan tool, read SWITCHED BATTERY voltage. If voltage is more than 3 volts, repair trans control relay output circuit for short to battery voltage. See Figure . If voltage is 3 volts or less, go to next step.
  3. Turn ignition off. Disconnect TCM connector. Turn ignition on. Use scan tool in voltmeter mode. On F24S and FJ22 models, measure voltage at terminal No. 2 of solenoid pack harness connector. On all other models, measure voltage at terminal No. 1 of solenoid pack harness connector. On all models, if voltage is 3 volts or less, go to next step. If voltage is more than 3 volts, repair 2-4 pressure switch sense circuit for short to battery voltage.
  4. Use scan tool in voltmeter mode. On F24S and FJ22 models, measure voltage at terminal No. 1 on solenoid pack connector. On all other models, measure voltage at terminal No. 2 on solenoid pack connector. On all models, if voltage is 3 volts or less, go to next step. If voltage is more than 3 volts, repair L-R pressure switch sense circuit for short to battery voltage.
  5. Use scan tool in voltmeter mode. On F24S and FJ22 models, measure voltage at terminal No. 5 on solenoid pack connector. On all other models, measure voltage at terminal No. 3 on solenoid pack connector. On all models, if voltage is 3 volts or less, go to next step. If voltage is more than 3 volts, repair OD pressure switch sense circuit for short to battery voltage.
  6. Use scan tool in voltmeter mode. On F24S and FJ22 models, measure voltage at terminal No. 7 on solenoid pack connector. On all other models, measure voltage at terminal No. 5 on solenoid pack connector. On all models, if voltage is 3 volts or less, go to next step. If voltage is more than 3 volts, repair UD solenoid control circuit for short to battery voltage.
  7. Use scan tool in voltmeter mode. On F24S and FJ22 models, measure voltage at terminal No. 8 on solenoid pack connector. On all other models, measure voltage at terminal No. 6 on solenoid pack connector. On all models, if voltage is 3 volts or less, go to next step. If voltage is more than 3 volts, repair OD solenoid control circuit for short to battery voltage.
  8. Use scan tool in voltmeter mode. On F24S and FJ22 models, measure voltage at terminal No. 4 on solenoid pack connector. On all other models, measure voltage at terminal No. 7 on solenoid pack connector. On all models, if voltage is 3 volts or less, go to next step. If voltage is more than 3 volts, repair L-R solenoid control circuit for short to battery voltage.
  9. Use scan tool in voltmeter mode. On F24S and FJ22 models, measure voltage at terminal No. 3 on solenoid pack connector. On all other models, measure voltage at terminal No. 8 on solenoid pack connector. On all models, if voltage is 3 volts or less, replace TCM. If voltage is more than 3 volts, repair 2-4 solenoid control circuit for short to battery voltage.
