Data List / Active Test [08/2019 - ]

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 power switch on (IG).
3. Turn the Techstream on.
4. Enter the following menus: Chassis / Front Recognition Camera / Data List.
5. Read the Data List according to the display on the Techstream.

   Chassis > Front Recognition Camera > Data List 

   Tester Display	Measurement Item	Range	Normal Condition	Diagnostic Note
   Total Distance Traveled	-	-	-	Cannot be used
   Total Distance Traveled - Unit	-	-	-	Cannot be used
   VGRS ECU Equipped Information	Existence of VGRS system	Absence / Presence	Absence: Not equipped Presence: Equipped	If the value of this item differs from the specifications of the vehicle, a forward recognition camera which was installed to another vehicle may be installed or the forward recognition camera may be malfunctioning.
   DRS System Equipped Information	Existence of DRS system	Absence / Presence	Absence: Not equipped Presence: Equipped	If the value of this item differs from the specifications of the vehicle, a forward recognition camera which was installed to another vehicle may be installed or the forward recognition camera may be malfunctioning.
   Vehicle Information (Steering Wheel Position)	Vehicle information (steering wheel position) stored in forward recognition camera	Unknown / Left / Right	Actual steering wheel position displayed	If the value of this item differs from the specifications of the vehicle, a forward recognition camera which was installed to another vehicle may be installed or the forward recognition camera may be malfunctioning.
   HV Equipped Information	Vehicle information (conventional/hybrid) stored in forward recognition camera	Non-HV / HV	Non-HV: Conventional vehicle HV: Hybrid vehicle	If the value of this item differs from the specifications of the vehicle, a forward recognition camera which was installed to another vehicle may be installed or the forward recognition camera may be malfunctioning.
   Steering Vibrator Equipped Information	Existence of steering vibrator	Absent / Present	Absent: Not equipped Present: Equipped	If the value of this item differs from the specifications of the vehicle, a forward recognition camera which was installed to another vehicle may be installed or the forward recognition camera may be malfunctioning.
   Buzzer (Line) Equipped Information	Existence of forward recognition camera buzzer	Absent / Present	Absent: Not equipped Present: Equipped	If the value of this item differs from the specifications of the vehicle, a forward recognition camera which was installed to another vehicle may be installed or the forward recognition camera may be malfunctioning.
   Front Recognition Camera Low Temperature	Existence of forward recognition camera low temperature malfunction	Not Low Temperature / Low Temperature	Not Low Temperature: Approximately -30°C (-22°F) or more Low Temperature: Less than approximately -30°C (-22°F)	If the value of this item is "Low Temperature", "Front Camera Unavailable" is displayed on the multi-information display. If system operation does not return even after warming the cabin, the forward recognition camera may be malfunctioning. If the value of this item is "Low Temperature", Vehicle Control History X2016 is stored.
   Front Recognition Camera High Temperature 1	Existence of forward recognition camera high temperature malfunction	Not High Temperature / High Temperature	Not High Temperature: Less than approximately 80°C (176°F) High Temperature: Approximately 80°C (176°F) or more	If the value of this item is "High Temperature", the front camera system is temporarily unavailable. If system operation does not return even after cooling the cabin for 10 minutes or more, the forward recognition camera may be malfunctioning. If the value of this item is "High Temperature", Vehicle Control History X2016 is stored. HINT: During summer time, it is possible for the windshield glass to exceed 100°C (212°F).
   Front Recognition Camera High Temperature 2	Existence of forward recognition camera high temperature malfunction	Not High Temperature / High Temperature	Not High Temperature: Less than approximately 65°C (149°F) High Temperature: Approximately 65°C (149°F) or more	If the value of this item is "High Temperature", the automatic high beam system is temporarily unavailable. If system operation does not return even after cooling the cabin for 10 minutes or more, the forward recognition camera may be malfunctioning. HINT:  During summer time, it is possible for the windshield glass to exceed 100°C (212°F).
   Heater Available Information	Existence of forward recognition with heater hood sub-assembly	Absence / Presence	Absence: w/o Forward recognition with heater hood sub-assembly Presence: w/ Forward recognition with heater hood sub-assembly	The forward recognition camera monitors the flow of current through the forward recognition with heater hood sub-assembly. If the value of this item is "Absence", a new forward recognition camera may have been installed when there is an open in the forward recognition with heater hood sub-assembly circuit.
   Heater Control Permit	Forward recognition with heater hood sub-assembly control permission	Not Allow / Allow	Not Allow: Forward recognition with heater hood sub-assembly control prohibited Allow: Forward recognition with heater hood sub-assembly control activated	If the value of this item is "Not Allow", the following may be the cause of the forward recognition with heater hood sub-assembly control prohibition: DTCs stored by forward recognition camera Vehicle Control History stored by forward recognition camera Air conditioning system malfunction Communication malfunction between forward recognition camera and air conditioning amplifier assembly
   Heater Control	Forward recognition with heater hood sub-assembly control state	Not Control / Under Control	Not Control: Forward recognition with heater hood sub-assembly control not performed Under Control: Forward recognition with heater hood sub-assembly control being performed	If the value of Heater Control Permit is "Allow" and the ambient temperature is 10°C (50°F) or less, the value of this item may repeatedly change between "Under Control" and "Not Control". (w/ Windshield Deicer System: When the windshield deicer is operating, the value of this item will be "Not Control".)
