DTC Diagnosis Procedure
1.CHECK TCM INPUT SIGNALS
With M.U.T.-III SE
  1. Start the engine.
  2. Select “Data List” in “TRANSMISSION”.
  3. Select “D POSITION SW”, “N POSITION SW”, “R POSITION SW”, and “P POSITION SW”.
  4. Check ON/OFF of each monitor item.
    Monitor itemTest conditionCondition
    D POSITION SWShift position: “D” positionOn
    Other than the aboveOff
    N POSITION SWShift position: “N” positionOn
    Other than the aboveOff
    R POSITION SWShift position: “R” positionOn
    Other than the aboveOff
    P POSITION SWShift position: “P” positionOn
    Other than the aboveOff
Without M.U.T.-III SE
  1. Start the engine.
  2. Disconnect TCM connector.
  3. The ignition switch is ON.
  4. Check voltage between TCM harness connector terminals and ground.
