Toyota Tacoma 2015-2018 CAN Workshop Manual

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.
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.
When using the Techstream with the ignition switch off to troubleshoot:
Connect the Techstream to the DLC3 and turn a courtesy light switch on and off at 1.5-seconds
intervals until communication between the Techstream and vehicle begins.
(1) Turn the ignition switch off.
(2) Connect the Techstream to the DLC3.
(3) Turn the ignition switch to ON.
(4) Turn the Techstream on.
(5) Enter the following menus: Body Electrical / Smart Key / Data List.
(6) According to the display on the Techstream, read the "Data List".
