Data List / Active Test

1. DATA LIST 

   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 the ON position.
   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.

   Hybrid Vehicle Control ECU (Cruise Control): 

   DIAGNOSTIC NOTE
   
   

   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.: 1 km/h (0.6 mph), max.: 255 km/h (158 mph)	Actual stored vehicle speed	-
   Stp Light SW M-CPU	Stop light switch signal (Main CPU)/ON or OFF	ON: Brake pedal depressed OFF: Brake pedal released	-
   Throttle Opening Angle	Required throttle opening angle / min.: 0°, max.: 125°	Actual required throttle opening	-
   Cruise Control	Cruise control system active condition / ON or OFF	ON: Cruise control activated OFF: Cruise control inactivated	-
   Main SW M-CPU	Main switch signal (Main CPU) / ON or OFF	ON: Main switch ON (Pushed on) OFF: Main switch OFF (Pushed off)	"3"
   CCS Ready M-CPU	Cruise control system standby condition (Main CPU) / ON or OFF	Each time main switch is pushed, ON is displayed and then OFF is displayed	"1"
   CCS Indicator M-CPU	Cruise indicator signal (Main CPU) / ON or OFF	ON: "CCS READY" ON OFF: "CCS READY" OFF	"2"
   Cancel Switch	CANCEL switch signal / ON or OFF	ON: CANCEL switch ON OFF: CANCEL switch OFF	-
   SET/COAST Switch	-/SET switch signal / ON or OFF	ON: -/SET switch ON OFF: -/SET switch OFF	-
   RES/ACC Switch	+/RES switch signal / ON or OFF	ON: +/RES switch ON OFF: +/RES switch OFF	-
   Cruise Operation Status	PNP switch signal (D position) / ON or OFF	ON: Shift lever on D OFF: Shift lever not on D	-
   Vehicle Spd Change	Vehicle speed change / ON or OFF	ON: Change OFF: Not change	-
   # Codes	Number of DTC recorded / 0 to 255	Min: 0 Max: 3	-
   HINT: "3" is OK but "1" is NG → Hybrid vehicle control ECU failure. "1" is OK but "2" is NG → DTC output or hybrid vehicle control ECU failure. "3" is but cruise indicator not turn on → CRUISE main indicator or wire harness or hybrid vehicle control ECU failure.

2. ACTIVE TEST 

   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 the ON position.
   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.
