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 to ON.
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.
   CRUISE CONTROL (ECM)
   
   

   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	Cruise control memorized speed/min.: 0 km/h (0 mph), max.: 200 km/h (125 mph)	Actual stored vehicle speed	-
   Throttle Opening Angle	Throttle opening angle/min.: 0 degrees, max.: 125 degrees	Actual demanded throttle angle	-
   Cruise Control	Cruise control system active condition/ON or OFF	ON: Cruise control activated OFF: Cruise control deactivated	-
   Main SW M-CPU	Main switch signal (Main CPU)/ON or OFF	ON: Main switch depressed OFF: Main switch released	3
   CCS Ready M-CPU	Cruise control system standby condition (Main CPU)/ON or OFF	Each time main switch is pushed, ON/OFF changes	1
   CCS Indicator M-CPU	Cruise indicator signal (Main CPU)/ON or OFF	ON: Cruise main indicator light on OFF: Cruise main indicator light off	2
   Cancel Switch	CANCEL switch signal/ON or OFF	ON: While switch is being operated OFF: Switch not operated	-
   SET/COAST Switch	SET/COAST switch signal/ON or OFF	ON: While switch is being operated OFF: Switch not operated	-
   RES/ACC Switch	RES/ACC switch signal/ON or OFF	ON: While switch is being operated OFF: Switch not operated	-
   Stp Light SW M-CPU	Stop light switch signal (Main CPU)/ON or OFF	ON: Brake pedal depressed OFF: Brake pedal released	-
   Cruise Operation Status	PNP switch signal (D position)/ON or OFF	ON: Shift lever in D OFF: Shift lever not in D	-
   Brake Cancel Switch	Brake Cancel signal/ON or OFF	ON: Brake pedal depressed OFF: Brake pedal released	-

   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 the cruise main indicator light does not illuminate → Cruise main indicator light, wire harness, or ECM failure

HINT: 

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 to ON.
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 to ON to proceed with Active Test using the Techstream.

   COMBINATION METER
   
   

   Tester Display	Test Part	Control Range	Diagnostic Note
   Indicat. Lamp Cruise	Cruise main indicator light	OFF or ON	Operate with IG ON and the vehicle is stopped
   Indicat. SET	Cruise control SET indicator light	OFF or ON	Operate with IG ON and the vehicle is stopped
