Test TC-12D - Torque Converter Clutch (TCC) Solenoid/Transmission Relay Circuit

CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
NOTE: Perform TEST TC-12A  before proceeding. For connector terminal identification, see CONNECTOR IDENTIFICATION . For appropriate wiring diagram, see WIRING DIAGRAMS . Perform VERIFICATION TEST VER-1A  after each repair.
  1. Turn ignition off. Disconnect transmission solenoid connector. Inspect connector and terminals for damage. Repair connector and terminals as necessary. If connector and terminals are okay, go to next step.
  2. Using an external ohmmeter, check resistance between terminal No. 11 on PCM White connector and engine ground. If resistance is less than 5 ohms, repair short to ground in TCC solenoid circuit. If resistance is 5 ohms or more, go to next step.
  3. Check resistance between transmission relay output circuit on transmission solenoid connector and engine ground. If resistance is less than 5 ohms, repair short in transmission relay output circuit. If resistance is 5 ohms or more, replace transmission solenoid pack.
