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.

NOTICE:

In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

(a) Warm up the engine.

(b) Turn the ignition switch off.

(d) Turn the ignition switch to ON.

(e) Turn the Techstream on.

(f) Enter the following menus: Powertrain / Transmission / Data List.

(g) According to the display on the Techstream, read the Data List.

Transmission

Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
Vehicle Speed	Vehicle speed/ Min.: 0 km/h (0 mph) Max.: 255 km/h (158 mph)	Actual vehicle speed	This is the current vehicle speed. The vehicle speed is detected using the wheel speed sensors. There is a delay in when the vehicle speed data is displayed. Therefore, even if the vehicle speed listed in the freeze frame data is 0 km/h (0 mph), this does not always mean that the malfunction occurred when the vehicle was stopped.
Engine Speed	Engine speed/ Min.: 0 rpm Max.: 16383 rpm	550 to 650 rpm: Idling	When the crankshaft position sensor is malfunctioning, "Engine Speed" is approximately 0 rpm or varies greatly from the actual engine speed.
Calculate Load	Load calculated by ECM/ Min.: 0% Max.: 100%	-	This is the engine load calculated based on the intake pressure. Calculate Load = Actual intake manifold pressure / maximum intake manifold pressure x 100 (%) (For example, when the actual intake manifold pressure is the same as atmospheric pressure, Calculate Load is 100%.)
Coolant Temperature	Engine coolant temperature/ Min.: -40°C (-40°F) Max.: 140°C (284°F)	75 to 100°C (167 to 212°F): After warming up	This is the engine coolant temperature. HINT: After warming up the engine, the engine coolant temperature is 75 to 100°C (167 to 212°F). After a long soak, the engine coolant temperature, intake air temperature and ambient air temperature are approximately equal. If the value is -40°C (-40°F), or 140°C (284°F), the sensor circuit is open or shorted. Check if the engine overheats when the value indicated is higher than 140°C (284°F).
Intake Air Temperature	Intake air temperature/ Min.: -40°C (-40°F) Max.: 140°C (284°F)	Equivalent to ambient air temperature	After a long soak, the engine coolant temperature, intake air temperature and ambient air temperature are approximately equal. If the value is -40°C (-40°F), or 140°C (284°F), the sensor circuit is open or shorted.
Engine Run Time	Engine run time/ Min.: 0 sec Max.: 65535 sec	Time after engine start	This is the time elapsed since the engine started. HINT: The time is counted only while the engine is running.
Battery Voltage	Battery voltage/ Min.: 0 V Max.: 65.5 V	11 to 14 V: Idling	If 11 V or less, characteristics of some electrical components may change.
BATT Voltage	Battery voltage/ Min.: 0 V Max.: 79.998 V	11 to 14 V: Idling	If 11 V or less, characteristics of some electrical components may change.
Throttle Position Sensor No.1 Voltage %	Absolute throttle position sensor (No. 1)/ Min.: 0% Max.: 100%	10 to 22%: Accelerator pedal fully released 64 to 96%: Accelerator pedal fully depressed (engine running)	The No. 1 throttle position sensor output is converted using 5 V = 100%. HINT: If there are no throttle position sensor DTCs stored, it is possible to conclude that the throttle position sensor system is normal.
Starter SW	Starter signal/ ON or OFF	ON: Starter operating OFF: Starter not operating	-
Neutral Position SW	Park/neutral position switch status/ ON or OFF	ON: Shift lever in P or N OFF: Shift lever not in P or N	When the shift lever position displayed on the Techstream differs from the actual position, adjustment of the park/neutral position switch or the shift cable may be incorrect.

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.

(a) Warm up the engine.

(b) Turn the ignition switch off.

(d) Turn the ignition switch to ON.

(e) Turn the Techstream on.

(f) Enter the following menus: Powertrain / Transmission / Active Test.

(g) According to the display on the Techstream, perform the Active Test.

Transmission

Tester Display	Test Part	Control Range	Diagnostic Note
Activate the TC Terminal	Connects and disconnects TC and TE1. (changes to the fluid temperature detection mode)	ON/OFF	[Vehicle Condition] Ignition switch ON Vehicle stopped
Activate the Solenoid (SLU)	Operates shift solenoid valve SLU	ON/OFF	[Vehicle Condition] Ignition switch ON Engine stopped Shift lever in P or N
Activate the Solenoid (SLT)*	Operates shift solenoid valve SLT to raise the line pressure.	ON/OFF HINT: ON: No action (normal operation) OFF: Line pressure up (When the Active Test of "Activate the Solenoid (SLT)" is performed, the ECM commands the shift solenoid valve SLT to turn off).	[Vehicle Condition] Vehicle Stopped Engine idling
Activate the Lock Up Solenoid	Controls the shift solenoid valves SLU and SL to set the automatic transmission to the lock-up condition.	ON/OFF Start/Stop	Can be used to check shift solenoid valves SLU and SL operation. [Vehicle Condition] Vehicle speed: 60 km/h (36 mph) or more
Activate the Solenoid (SL)	Operates shift solenoid valve SL	ON/OFF	[Vehicle Condition] Ignition switch ON Engine stopped Shift lever in P or N
Control the Shift Position	Operates the shift solenoid valves to allow gears to be selected manually.	1st/2nd/3rd/4th/5th/6th Start/Stop	Can be used to check the operation of the shift solenoid valves. Up-shifts and down-shifts should be performed consecutively. A 10 second interval is required between gear changes. Do not down-shift at high speeds. Doing so will damage the automatic transmission. [Vehicle Condition] 50 km/h (31 mph) or less
Activate the Solenoid (SL1)	Operates shift solenoid valve SL1	ON/OFF	[Vehicle Condition] Ignition switch ON Engine stopped Shift lever in P or N
Activate the Solenoid (SL2)	Operates shift solenoid valve SL2	ON/OFF	[Vehicle Condition] Ignition switch ON Engine stopped Shift lever in P or N
Activate the Solenoid (SL3)	Operates shift solenoid valve SL3	ON/OFF	[Vehicle Condition] Ignition switch ON Engine stopped Shift lever in P or N
Activate the Solenoid (SL4)	Operates shift solenoid valve SL4	ON/OFF	[Vehicle Condition] Ignition switch ON Engine stopped Shift lever in P or N

*: The "Activate the Solenoid (SLT)" Active Test is performed to allow confirmation that the line pressure changes. The line pressure changes are confirmed using the same SST that is used for the Hydraulic Test (See page HINT: ).

HINT:

Note that the pressure readings for the Active Test and Hydraulic Test are different.
