Data List / Active Test

HINT:

Using the Techstream 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 Techstream to the DLC3.
2. Turn the ignition switch on (IG).
3. Turn the Techstream on.
4. Enter the following menus: Powertrain / Cruise Control / Data List.
5. Read the Data List according to the display on the Techstream.

   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 of 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 position OFF: Shift lever except in D position	-
   # Codes	Number of DTC recorded / 0 to 255	Min.: 0 Max.: 4	-
   HINT: "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 light, wire harness, or ECM failure

Using the Techstream 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 Techstream to the DLC3.
2. Turn the ignition switch on (IG).
3. Turn the Techstream on.
4. Enter the following menus: Body Electrical / Combination Meter / Active Test.
5. Perform "Active Test" according to the display on the Techstream.

   HINT:

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