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

   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	-
   Main SW M-CPU	Main SW signal (Main CPU)/ON or OFF	ON: Cruise control main switch pushed OFF: Cruise control main switch not pushed	3
   CCS Ready M-CPU	Cruise control system standby condition (Main CPU)/ON or OFF	ON: Cruise control main switch (Main CPU) is SET OFF: Cruise control main switch (Main CPU) is UNSET	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: 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	-
   Stp Light SW M-CPU*1	Stop light SW signal (Main CPU)/ON or OFF	ON: Brake pedal depressed OFF: Brake pedal released	-
   Cruise Operation Status	Shift lever position signal/ON or OFF	ON: Shift lever in D or S (5th or 4th) OFF: Shift lever except in D or S (5th or 4th)	for U250E
   	Shift lever position signal/ON or OFF	ON: Shift lever in D or 3 OFF: Shift lever except in D or 3	for U341E, U140F
   	Clutch switch signal/ON or OFF	ON: Clutch pedal released OFF: Clutch pedal depressed	for M/T
   Brake Cancel Switch*2	Brake Cancel Signal/ON or OFF	ON: Brake pedal depressed OFF: Brake pedal released	-

   *1: for 2ZR-FE

   *2: for 2AZ-FE

   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

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 trouble shooting 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 the Active Test using the Techstream.
