Scan Tool Testing and Procedures

2012 Lexus CT 200h L4-1.8L (2ZR-FXE) HybridSECTION Scan Tool Testing and Procedures




WINDOW / GLASS: POWER WINDOW CONTROL SYSTEM: DATA LIST / ACTIVE TEST

1. 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) Connect the Techstream to the DLC3.

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

(c) Turn the Techstream on.

(d) Enter the following menus: Body Electrical / (desired system) / Data List.

(e) Read the Data List according to the display on the Techstream.

Master Switch (Multiplex Network Master Switch Assembly)





D-Door Motor (Power Window Regulator Motor Assembly (for Driver Side))





P-Door Motor (Power Window Regulator Motor Assembly (for Front Passenger Side))





RL-Door Motor (Power Window Regulator Motor Assembly (for Rear LH Side))





RR-Door Motor (Power Window Regulator Motor Assembly (for Rear RH Side))





Main Body (Main Body ECU (Multiplex Network Body ECU))





2. ACTIVE TEST

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.

(a) Connect the Techstream to the DLC3.

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

(c) Turn the Techstream on.

(d) Enter the following menus: Body Electrical / (desired system) / Active Test.

(e) Perform the Active Test according to the display on the Techstream.

CAUTION:
Be careful to avoid injuries as this test causes vehicle parts to move. During the Active Test, the jam protection function will not operate.

D-Door Motor (Power Window Regulator Motor Assembly (for Driver Side))





P-Door Motor (Power Window Regulator Motor Assembly (for Front Passenger Side))





RL-Door Motor (Power Window Regulator Motor Assembly (for Rear LH Side))

  • You smell fuel, burning insulation, or see smoke.
  • Brakes feel soft, pull hard to one side, or make grinding noises.
  • The engine overheats, stalls repeatedly, or misfires under load.
  • You are missing required tools, torque specs, or safe lifting equipment.
  • You are not confident in the next step or safety outcome.
