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) Connect the Techstream to the DLC3.

(b) Turn the engine switch on (IG).

(d) Enter the following menus: Body Electrical / (desired system) / Data List.

(e) Read the Data List according to the display on the Techstream.

Body Electrical > Power Source Control > Data List

Tester Display	Measurement Item	Range	Normal Condition	Diagnostic Note
Shift P Signal	Shift position P	OFF or ON	OFF: Shift lever not in P ON: Shift lever in P	Use this item to determine if the park/neutral position switch is malfunctioning.
Steering Unlock Switch	State of steering unlock sensor signal output from steering lock ECU (steering lock actuator or upper bracket assembly)	OFF or ON	OFF: Steering locked ON: Steering unlocked	When the shift lever is in P and the engine switch is off, if any door is opened or closed, the steering is locked. When the electrical key transmitter sub-assembly is in the cabin and the engine switch is turned on (ACC) or on (IG), the steering unlocks. The engine cannot be started when the steering unlock signal is off.
Stop Light Switch1	State of brake pedal	OFF or ON	OFF: Brake pedal released ON: Brake pedal depressed	Use this item to determine if the stop light switch assembly is malfunctioning. The engine cannot be started when this item is OFF. If the stop light switch assembly is malfunctioning, the engine can be started by pressing and holding the engine switch for a certain period of time.
Start Switch1	Engine switch 1 status	OFF or ON	OFF: Engine switch not pressed ON: Engine switch pressed	If the engine switch is pressed for a short time, the display may not change. Use this item to determine if the engine switch input signal is malfunctioning.
Start Switch2	Engine switch 2 status	OFF or ON	OFF: Engine switch not pressed ON: Engine switch pressed	Backup for engine switch 1. However, when the engine switch is pressed and held, the control functions only when both engine switch 1 and 2 are normal. Behaves the same way as engine switch 1.
Neutral SW/ Clutch SW	Shift position (P and N)	OFF or ON	OFF: Shift lever in any position other than P or N ON: Shift lever in P or N	Use this item to determine if the park/neutral position switch is malfunctioning. When the engine cannot be started due to a park/neutral position switch malfunction, OFF is displayed.
Latch Circuit	Status of IG related backup circuits	OFF or ON	OFF: Engine switch off ON: Engine switch on (IG)	Operates in almost the same manner as the IG relay. When the engine switch is on (ACC), OFF is displayed.
Starter Request Signal	Engine start request signal status	OFF or ON	OFF: The engine switch is not pressed ON: With the shift lever in P and the brake pedal depressed, the engine switch is pressed and held	When the engine cannot be started due to a start request signal malfunction, OFF is displayed. When the engine switch is pressed, the duration of time that ON is displayed will be extremely short. As such, the engine switch needs to be pressed and held for a certain period of time.
ACC Relay Monitor	ACC relay activation	OFF or ON	OFF: Engine switch off ON: Engine switch on (ACC)	When the engine switch is on (IG), ON is displayed. While the engine is cranking, OFF is displayed.

Park Signal Mismatch	P position signal malfunction	No or Yes	No: Signal normal Yes: Signal malfunction (signals via CAN communication and direct line do not match)	Even when Yes is displayed, it is still possible to turn the engine switch off (the power source mode will not be stuck in on (ACC) or on (IG)).
Str Lock/Unlock Wait T-Out	Steering lock or unlock malfunction	No or Yes	No: Lock and unlock normal Yes: Lock or unlock malfunction (e.g. steering lock is stuck etc.)	When the engine cannot be started due to a steering lock or unlock malfunction, Yes is displayed.
Key Certif Wait T-Out	Key verification malfunction	No or Yes	No: Verification normal Yes: Verification error (Detected due to the electrical key transmitter sub-assembly ID code and the ID code stored in the certification ECU (smart key ECU assembly) not matching)	When the engine cannot be started due to a key verification error, Yes is displayed.
IG Circuit	IG relay coil circuit malfunction	OK or NG	OK: Circuit normal NG: Circuit malfunctioning	Use this item to determine if the IG relay is malfunctioning. When the engine cannot be started due to an IG relay malfunction, NG is displayed.
