  5. STEP 5. Measure the signal voltage at ECM connector C-120 < 2.4L engine-M/T > or C-122 < 3.0L engine-M/T >, or PCM connector C-117 < 2.4L engine-A/T > or C-119 < 3.0L engine-A/T >. 
    1. Disconnect ECM connector C-120 < 2.4L engine-M/T > or C-122 < 3.0L engine-M/T >, or PCM connector C-117 < 2.4L engine-A/T > or C-119 < 3.0L engine-A/T >.
    2. Turn the ignition switch to the "ON" position and the auto-cruise control MAIN switch to the "ON" position.

    3. Measure the voltage between ECM connector C-120 terminal 87 < 2.4L engine-M/T > or C-122 terminal 79 < 3.0L engine-M/T >, or PCM connector C-117 terminal 79 < 2.4L engine-A/T > or C-119 terminal 79 < 3.0L engine-A/T > and ground.
      • The voltage should measure between 4.0 and 5.5 volts.
    4. Turn the auto-cruise control MAIN switch to the "OFF" position and the ignition switch to the "LOCK" (OFF) position.

    Q: Is the measured voltage between 4.0 and 5.5 volts? 

    YES  : Check that DTC 17 is not set. If DTC 17 is not set, It can be assumed that this malfunction is intermittent. (Refer to HOW TO COPE WITH INTERMITTENT MALFUNCTIONS ). If DTC 17 is set, replace the ECM < M/T > or PCM < A/T >, and then Go to  Step 9.

    NO:  Go to Step 6.

    3. Measure the voltage between auto-cruise control-ECU connector C-21 terminal 2 and ground by backprobing.
      • The voltage should measure between 4.0 and 5.5 volts. (When accelerator pedal is depressed.)
      • The voltage should measure between 2.5 volts or less. (When accelerator pedal is released.)
    4. Turn the auto-cruise control MAIN switch to the "OFF" position and the ignition switch to the "LOCK" (OFF) position.

    Q: Are all of the measured voltages satisfied? 

    YES  : Check that DTC 17 is not set. If DTC 17 is not set, It can be assumed that this malfunction is intermittent. (Refer to HOW TO COPE WITH INTERMITTENT MALFUNCTIONS ). If DTC 17 is set, replace the auto-cruise control-ECU (Refer to AUTO-CRUISE CONTROL  ), and then go to Step 9.
