Toyota Tacoma (2015-2018) Service Manual: Data List / Active Test
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) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Body Electrical / Main Body / Data List.
(e) Read the Data List according to the display on the Techstream.

Rear Occupant Classification Sensor LH Collision Detection (B1787)
DESCRIPTION
DTC B1787 is set when the occupant detection ECU receives a collision detection
signal, which is sent by the occupant classification sensor rear LH when an accident
occurs.
DTC B1787 is also set when the front seat with adjuster frame assembly RH is
subjected to a strong impact, ...
Front Radar Sensor Incorrect Axial Gap (C1A11,C1A14)
DESCRIPTION
When the system determines that the vehicle is driving straight ahead based on
signals from the yaw rate and acceleration sensor (airbag sensor assembly), etc.,
the millimeter wave radar sensor assembly performs self-diagnosis to check if the
sensor beam axis is misaligned.
