Title: PARKING BRAKE: ELECTRIC PARKING BRAKE SYSTEM (w/o Vacuum Brake Booster): DATA LIST / ACTIVE TEST; 2019 MY RAV4 RAV4 HV [11/2018 - 02/2019]

DATA LIST / ACTIVE TEST

READ 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) Turn the power switch off.

(b) Connect the Techstream to the DLC3.

(c) Turn the power switch on (IG).

(d) Turn the Techstream on.

(e) Enter the following menus: Chassis / Electric Parking Brake / Data List.

(f) Check the values by referring to the table below.
