TEST TC-12A - TORQUE CONVERTER CLUTCH (TCC) SOLENOID/TRANS RELAY CKT

Note. Test applies to vehicles equipped with automatic transmission only. For connector terminal ID, see CONNECTOR IDENTIFICATION DIRECTORY. For component location see wiring diagram in the WIRING DIAGRAMS - 2.4L article.

  1. If vehicle is not equipped with 4-speed Electronic Automatic Transmission (EATX), perform TEST TC-12E. If vehicle is equipped with 4-speed EATX, go to next step.
  2. If TRANS 12 VOLT SUPPLY RELAY CNTRL CIRCUIT DTC is also set, perform TEST TC-173A. If TRANS 12 VOLT SUPPLY RELAY CNTRL CIRCUIT DTC IS NOT SET, use scan tool to perform TCC SYSTEM TEST. If engine does not stall, go to step 6). If engine stalls, go to next step.
  3. Condition required to set DTC is not present at this time. TCC SOLENOID CIRCUIT DTC sets if an open or shorted circuit exists in TCC solenoid circuit. Possible causes are: open or shorted wiring to TCC solenoid, open fused ignition switch output circuit, defective connector terminals, or defective TCC solenoid. Go to next step.
  4. Inspect all related wiring and connectors. Repair wiring and connections as necessary and perform TEST VER-2A. If wiring is okay, go to next step.
  5. Using scan tool, clear DTCs. Actuate TCC solenoid and check for DTCs. Wiggle wiring harness from TCC solenoid to PCM and note if TCC SOLENOID CIRCUIT DTC resets. If DTC resets, repair wiring harness as necessary and perform TEST VER-2A. If DTC does not reset, see INACTIVE DTC CONDITION. Test is complete.
  6. Turn ignition off. Disconnect Transmission (TRANS) solenoid connector. Inspect connector and terminals for damage. Repair connector and terminals as necessary and perform TEST VER-2A. If connector and terminals are okay, go to next step.
  7. Turn ignition on. Using scan tool, actuate TRANS control relay and check voltage on TRANS solenoid connector, TRANS relay output circuit (White/Brown wire). If voltage does not cycle from zero to more than 10 volts, perform TEST TC-12B. If voltage cycles from zero to more than 10 volts, go to next step.
  8. Turn ignition off. Disconnect Powertrain Control Module (PCM) White connector. Inspect connector and terminals for damage. Repair connector and terminals as necessary and perform TEST VER-2A. If connector and terminals are okay, go to next step.
  9. Turn ignition on. Using scan tool in voltmeter mode, check voltage on PCM White connector, TCC solenoid control circuit (Orange/Black wire). If voltage is more than 10 volts, perform TEST TC-12B. If voltage is 10 volts or less, go to next step.
  10. Turn ignition off. Using an external ohmmeter, check resistance between ground and PCM White connector, TCC solenoid control circuit (Orange/Black wire). If resistance is less than 5 ohms, repair TCC solenoid control circuit for short to ground and perform TEST VER-2A. If resistance is 5 ohms or more, go to next step.
  11. Reconnect TRANS solenoid connector. Check resistance between ground and PCM White connector, solenoid control circuit (Orange/Black wire). If resistance is less than 5 ohms, replace TRANS solenoid and harness assembly and perform TEST VER-2A. If resistance is 5 ohms or more, go to next step.
  12. Remove TRANS control relay. Inspect relay connector and terminals for damage. Repair connector and terminals as necessary and perform TEST VER-2A. If connector and terminals are okay, go to next step.
  13. Check resistance between TRANS control relay connector, TRANS control relay output circuit (White/Brown wire) and PCM White connector, TCC solenoid control circuit (Orange/Black wire). If resistance is 26-40 ohms, replace PCM and perform TEST VER-2A. If resistance is more than 40 ohms, go to next step. If resistance is less than 26 ohms, perform TEST TC-12C.
  14. Disconnect TRANS solenoid connector. Inspect connector and terminals for damage. Repair connector and terminals as necessary and perform TEST VER-2A. If connector and terminals are okay, go to next step.
  15. Check resistance of TCC solenoid control circuit (Orange/Black wire) between PCM White connector and TRANS solenoid connector. If resistance is 5 ohms or more, repair open TCC solenoid control circuit and perform TEST VER-2A. If resistance is less than 5 ohms, replace TRANS solenoid and harness assembly and perform TEST VER-2A.

TEST TC-12B - TORQUE CONVERTER CLUTCH (TCC) SOLENOID/TRANS RELAY CKT

Note. Perform TEST TC-12A before proceeding. For connector terminal ID, see CONNECTOR IDENTIFICATION DIRECTORY. For component location see wiring diagram in the WIRING DIAGRAMS - 2.4L article.

  1. Remove Transmission (TRANS) control relay. Inspect relay connector and terminals for damage. Repair connector and terminals as necessary and perform TEST VER-2A. If connector and terminals are okay, go to next step.
  2. Turn ignition off. Check resistance between ground and TRANS control relay connector, TRANS control relay output circuit (White/Brown wire). If resistance is 5 ohms or more, repair short to ground in TRANS control relay output circuit and perform TEST VER-2A. If resistance is less than 5 ohms, go to next step.
  3. Check resistance of TRANS control relay output circuit (White/Brown wire) between TRANS control relay connector and TRANS solenoid connector. If resistance is more than 5 ohms, repair open TRANS control relay output circuit and perform TEST VER-2A. If resistance is 5 ohms or less, go to next step.
  4. Turn ignition on. Using scan tool, check voltage on TRANS control relay connector, B+ circuit (Red/White wire). If voltage is 10 volts or less, repair open fused B+ circuit and perform TEST VER-2A. If resistance is more than 10 volts, replace TRANS control relay and perform TEST VER-2A.
