CRUISE CONTROL SYSTEM DATA LIST / ACTIVE TEST


  1. READ DATA LIST

    Tech Tips

    Using the intelligent tester to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch on (IG).

    3. Turn the tester main switch on.

    4. Select the following menu items: Powertrain / Cruise Control / Data List.

    5. Read the Data List according to the display on the tester.

      ECM (Cruise Control):
      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      CCS Vehicle Spd Vehicle speed / min.: 0 km/h (0 mph), max.: 255 km/h (158 mph) Actual vehicle speed -
      CCS Mem Vehicle Spd Stored vehicle speed / min.: 0 km/h (0 mph), max.: 200 km/h (125 mph) Actual stored vehicle speed -
      Throttle Opening Angle Required throttle opening angle / min.: 0°, max.: 125° Actual required throttle opening angle -
      Cruise Control Cruise control system active condition / ON or OFF

      ON: Cruise control activated

      OFF: Cruise control deactivated

      -
      CCS Main SW M-CPU Main SW signal (Main CPU) / ON or OFF

      ON: Main switch ON

      OFF: Main switch OFF

      "3"
      CCS Ready M-CPU Cruise control system standby condition (Main CPU) / ON or OFF ON - OFF: Change ON/OFF each time main switch is pushed in. "1"
      CCS Indicator M-CPU Cruise indicator signal (Main CPU) / ON or OFF

      ON: "CRUISE" ON

      OFF: "CRUISE" OFF

      "2"
      Cancel Switch CANCEL SW signal / ON or OFF

      ON: CANCEL Switch ON

      OFF: CANCEL Switch OFF

      -
      SET/COAST Switch -/SET SW signal / ON or OFF

      ON: -/SET Switch ON

      OFF: -/SET Switch OFF

      -
      RES/ACC Switch +/RES SW signal / ON or OFF

      ON: +/RES Switch ON

      OFF: +/RES Switch OFF

      -
      Stop Light SW M-CPU Stop light SW signal (Main CPU) / ON or OFF

      ON: Brake pedal depressed

      OFF: Brake pedal released

      -
      Cruise Operation Status Transmission range sensor signal / ON or OFF

      ON: Shift lever in D or 4 position

      OFF: Shift lever except in D or 4 position

      -
      #Codes Number of DTC recorded / 0 to 255

      Min.: 0

      Max.: 4

      -

      Tech Tips

      "3" is OK but "1" is NG → ECM failure

      "1" is OK but "2" is NG → DTC output or ECM failure

      "3" is OK but cruise indicator does not turn on → CRUISE main indicator, wire harness, or ECM failure

  2. PERFORM ACTIVE TEST

    Tech Tips

    Using the intelligent tester to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.


    1. Connect the intelligent tester to the DLC3.

    2. Turn the ignition switch on (IG).

    3. Turn the tester main switch on.

    4. Select the following menu items: Body Electrical / Combination Meter / Active Test.

    5. Perform "Active Test" according to the display on the tester.

      Tech Tips

      The ignition switch must be turned on to proceed with the Active Test using the intelligent tester.
