Read the DTCs by following the directions on the screen. HINT: Refer to the Techstream operator's manual for further details.
2. CLEAR DTC Connect the Techstream to the DLC3. Turn the engine switch on (IG). Turn the Techstream on. Enter the following menus: Body Electrical/(desired system)/Trouble Codes. Erase the DTCs by following the directions on the screen. HINT: Refer to the Techstream operator's manual for further details.

DATA LIST/ACTIVE TEST

1. DATA LIST HINT: Using the Techstream to read the Data List allows values or status 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. NOTE: 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. Connect the Techstream to the DLC3. Turn the engine switch on (IG). Turn the Techstream on. Enter the following menus: Body Electrical/(desired system)/Data List / According to the display on Techstream, read the "Data List".
