Data List / Active Test [01/2023 - ]

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. Read the Data List according to the display on the Techstream.

   On-line Calibration Angle (Vertical)	-	-	-	Cannot be used
   On-line Calibration Angle (Roll Angle)	-	-	-	Cannot be used
   Front Recognition Camera Axis Adjusted Status	-	-	-	Cannot be used
   Front Recognition Camera Low Temperature	Whether low temperature malfunction of forward recognition camera exists or not	Not High Temperature or High Temperature	Not Low Temperature: Approximately -30°C (-22°F) or higher Low Temperature: Approximately -30°C (-22°F) or less	If this item is "Low Temperature", it will display that the camera is temporarily unavailable. If this item is "Low Temperature", X2016 is output in the vehicle control history.
   Front Recognition Camera High Temperature 1	Whether high temperature malfunction of forward recognition camera exists or not	Not High Temperature or High Temperature	Not High Temperature: Approximately 80°C (176°F) or less High Temperature: Approximately 80°C (176°F) or higher	If this item is "High Temperature", the camera will be temporarily unavailable. If this does not improve even if the inside of the vehicle is left cooled for at least 10 minutes, the forward recognition camera may be malfunctioning. If this item is "High Temperature", X2016 is output in the vehicle control history. HINT: In summertime, the windshield glass may reach 100°C (212°F) or higher
   Front Recognition Camera High Temperature 2	Whether high temperature malfunction of forward recognition camera exists or not	Not High Temperature or High Temperature	Not High Temperature: Approximately 65°C (149°F) or less High Temperature: Approximately 65°C (149°F) or higher	If this item is "High Temperature", the automatic high beam system will be temporarily unavailable. If this does not improve even if the inside of the vehicle is left cooled for at least 10 minutes, the forward recognition camera may be malfunctioning. HINT:  In summertime, the windshield glass may reach 100°C (212°F) or higher
   On-line Axis Alignment Error Code 31	Indicates whether on-line axis alignment error code 31 is present	Not Detected / Detected	Not Detected: error code not detected Detected: error code 31 is detected	If this item is "Detected", it can be inferred that the vehicle speed at the start of on-line axis alignment was in excess of 5 km/h (3 mph), and on-line axis adjustment did not start.
   On-line Axis Alignment Error Code 32	Indicates whether on-line axis alignment error code 32 is present	Not Detected / Detected	Not Detected: error code not detected Detected: error code 32 is detected	If this item is "Detected", it can be inferred that during on-line axis alignment, the field of view of the forward recognition camera was obstructed, causing on-line axis alignment to fail.
   On-line Axis Alignment Error Code 33	Indicates whether on-line axis alignment error code 33 is present	Not Detected / Detected	Not Detected: error code not detected Detected: error code 33 is detected	If this item is "Detected", it can be inferred that during on-line axis alignment, DTCs or vehicle control history (RoB) occurred, causing on-line axis alignment to fail.
   On-line Axis Alignment Error Code 34	Indicates whether on-line axis alignment error code 34 is present	Not Detected / Detected	Not Detected: error code not detected Detected: error code 34 is detected	If this item is "Detected", it can be inferred that the FOE value calculated via on-line axis alignment exceeded the normal range, causing on-line axis alignment to fail.
   On-line Axis Alignment Error Code 35	Indicates whether on-line axis alignment error code 35 is present	Not Detected / Detected	Not Detected: error code not detected Detected: error code 35 is detected	If this item is "Detected", it can be inferred that the FOE value calculated via on-line axis alignment could not be correctly written to memory.
   Heater Available Information	Whether a hot-wire heater exists in the forward recognition camera or not	Absence or Presence	Absence: w/o Heater Wire Heater Presence: w/ Heater Wire Heater	The forward recognition camera checks conductivity with the hot-wire heater. If this item is "Absence", a new forward recognition camera may have been installed with the hot-wire heater disconnected.
   Heater Control Permit	The control permission status of the hot-wire heater in the forward recognition camera	Not Allow or Allow	Not Allow: Hot-wire heater control not permitted Allow: Hot-wire heater control permitted	If this item is "Not Allow", the following statuses are likely. The forward recognition camera has stored vehicle control history The air conditioning system is malfunctioning Communication between the forward recognition camera and air conditioning amplifier assembly is lost
   Heater Control	The control status of the hot-wire heater in the forward recognition camera	Not Control or Under Control	Not Control: Hot-wire heater not controlled Under Control: Hot-wire heater controlled	If the hot-wire heater control permission item is "Allow" and the outside temperature is 10°C (50°F) or less, this item will repeatedly switch between "Not Control" and "Under Control". (For vehicles with whole surface deicers, this item will remain "No Control" when the whole surface deicer is in use.)

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. Perform Active Test according to the display on the Techstream.
