Test 13A - 3-4 Solenoid Circuit (DTC 22)
WARNING: This page is about a different car, the 1995 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Perform TEST 2A
before proceeding with this test. For connector terminal identification, see CONNECTOR IDENTIFICATION
. For wiring diagram, see WIRING DIAGRAM
. Perform TEST 3A - VERIFICATION TEST
after each repair.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- If DTC 23 is also present, go to TEST 17A . Turn ignition off. Disconnect Transmission Control Module (TCM). Turn ignition on. Use scan tool in voltmeter mode. Measure voltage at terminal No. E15 on TCM connector. If voltage is more than 1 volt, repair 3-4 shift solenoid circuit for short to battery voltage. If voltage is 1 volt or less, go to next step.
- Turn ignition off. Using scan tool in ohmmeter mode. Measure resistance at terminal E15 on TCM connector. If resistance is less than 5 ohms, go to step 5). If resistance is 5 ohms or more, go to next step.
- Use external ohmmeter. Measure resistance between terminals E15 and E16 on TCM connector. If resistance is 30-45 ohms, replace TCM. If resistance is not 30-45 ohms, go to next step.
- Disconnect transmission 8-pin connector. Use external ohmmeter. Measure resistance between terminal No. 6 of transmission 8-pin connector and terminal No. E15 of TCM connector. If resistance is less than 5 ohms, replace 3/4 shift solenoid. If resistance is 5 ohms or more, repair open 3-4 shift solenoid control circuit.
- Disconnect transmission 8-pin connector. Use scan tool in ohmmeter mode. Measure resistance at terminal No. 6 on transmission 8-pin connector. If resistance is less than 5 ohms, repair 3-4 shift solenoid control circuit for short to ground. If resistance is 5 ohms or more, replace 3-4 shift solenoid.
