TEST TC-35A - TORQUE CONVERTER CLUTCH SOLENOID CIRCUIT (DTC 37)

Note. For connector terminal identification, see CONNECTOR IDENTIFICATION in this article. For wiring diagram, see appropriate WIRING DIAGRAMS .

  1. Using DRB, erase trouble codes. On models with overdrive switch on instrument panel, go to TEST TC-35B. Using DRB, actuate Torque Converter Clutch (TCC) relay. If TCC relay does not click, go to step 5). If TCC relay clicks, condition required to set trouble code is not present at this time. Go to next step.
  2. TORQUE CONVERTER CLUTCH SOLENOID CIRCUIT trouble code sets if solenoid or relay control circuit (Orange/Black wire) is not in its proper state when monitored by Powertrain Control Module (PCM). Possible causes are: open or shorted solenoid or relay control circuit (Orange/Black wire), open or shorted solenoid or relay coil, and open 12-volt feed circuit (Dark Blue wire) to solenoid or relay. Go to next step.
  3. Inspect all related wiring and connectors. Repair as necessary. Perform «TEST VER-2»(ref-10889-S40837604532000111000000) . If no problems are found with wiring or connectors, go to next step.
  4. Using DRB, read trouble codes. TCC actuation test should still be running. Wiggle wiring harness from TCC solenoid relay to PCM. If TCC RELAY CONTROL CIRCUIT trouble code returns, repair wiring harness as necessary. Perform TEST VER-2. If TCC RELAY CONTROL CIRCUIT trouble code does not return, test is complete. Perform TEST VER-2.
  5. Disconnect TCC relay connector. Using DRB in voltmeter mode, check voltage on TCC solenoid connector terminal "A", ignition feed circuit (Dark Blue wire).
  6. If voltage is less than 10 volts, repair open Dark Blue wire. Perform TEST VER-2. If voltage is more than 10 volts, turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Using DRB in ohmmeter mode, check resistance of PCM connector terminal No. 54, TCC solenoid control circuit (Orange/Black wire).
  7. If resistance is less than 5 ohms, repair short to ground in Orange/Black wire. Perform TEST VER-2. If resistance is more than 5 ohms, go to next step.
  8. Using an external ohmmeter, check resistance of TCC solenoid control circuit (Orange/Black wire) between PCM connector terminal No. 54 and TCC solenoid connector. If resistance is more than 5 ohms, repair open Orange/Black wire. Perform TEST VER-2. If resistance is less than 5 ohms, reconnect TCC solenoid connector. Turn ignition on.
  9. Using DRB in voltmeter mode, check voltage on PCM connector terminal No. 54, TCC solenoid control circuit (Orange/Black wire). If voltage is more than 10 volts, replace PCM. Perform TEST VER-2. If resistance is less than 10 volts, replace TCC relay. Perform TEST VER-2.

TEST TC-35B - TORQUE CONVERTER CLUTCH SOLENOID CIRCUIT

Note. For connector terminal identification, see CONNECTOR IDENTIFICATION in this article. For wiring diagram, see appropriate WIRING DIAGRAMS .

  1. Using DRB, actuate Torque Converter Clutch (TCC) solenoid. Wait 10 seconds. Using DRB, read trouble codes. If TORQUE CONVERTER CLUTCH SOLENOID CIRCUIT trouble code does not return, go to next step. If TORQUE CONVERTER CLUTCH SOLENOID CIRCUIT trouble code returns, go to step 4).
  2. TCC actuation test should still be running. Wiggle wiring harness from TCC solenoid relay to PCM. Using DRB, read trouble codes. If TCC RELAY CONTROL CIRCUIT trouble code returns, repair wiring harness as necessary. Perform «TEST VER-2»(ref-10889-S40837604532000111000000) . If TCC RELAY CONTROL CIRCUIT trouble code does not return, condition required to set trouble code is not present at this time.
  3. TORQUE CONVERTER CLUTCH SOLENOID CIRCUIT trouble code sets if solenoid or relay control circuit (Orange/Black wire on AB, AN and BR bodies) is not in its proper state when monitored by PCM. Possible causes are: open or shorted solenoid or relay control circuit, open or shorted solenoid or relay coil, and open 12-volt feed circuit (Dark Blue wire on AB and AN bodies; Light Green/Black wire on BR body) to solenoid or relay. Test is complete. Perform TEST VER-2.
  4. Disconnect transmission solenoid connector. Using DRB in voltmeter mode, check voltage on transmission solenoid connector, ignition feed circuit (Dark Blue wire on AB and AN bodies; Light Green/Black wire on BR body). If voltage is less than 10 volts, repair Dark Blue wire, Light Green/Black wire or Light Blue wire as necessary. Perform TEST VER-2. If voltage is more than 10 volts, turn ignition off.
  5. Disconnect Powertrain Control Module (PCM) connector. Using DRB in ohmmeter mode, check resistance of PCM connector terminal No. 54, TCC solenoid control circuit (Orange/Black wire on AB, AN and BR bodies). If resistance is less than 5 ohms, repair short to ground in Orange/Black wire or Violet/Yellow wire. Perform TEST VER-2. If resistance is more than 5 ohms, go to next step.
  6. Using an external ohmmeter, check resistance of TCC solenoid control circuit (Orange/Black wire on AB, AN and BR bodies) between PCM connector terminal No. 54 and transmission solenoid connector. If resistance is more than 5 ohms, repair open Orange/Black wire or Violet/Yellow wire. Perform TEST VER-2. If resistance is less than 5 ohms, reconnect transmission solenoid connector. Turn ignition on.
  7. Using DRB in voltmeter mode, check voltage on PCM connector terminal No. 54, TCC solenoid control circuit (Orange/Black wire on AB, AN and BR bodies). If voltage is more than 10 volts, replace PCM. Perform TEST VER-2. If resistance is less than 10 volts, replace TCC solenoid. Perform TEST VER-2.
