Pre-Collision System

PRE-COLLISION: PRE-COLLISION SYSTEM: DATA LIST / ACTIVE TEST

1. DATA LIST

HINT
Using 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.

(a) Connect Techstream to the DLC3.

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

(c) Turn the tester on.

(d) Enter the following menus: Body Electrical / Pre-Collision / Data List.

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

2. ACTIVE TEST

HINT
Using 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 Techstream to the DLC3.

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

(c) Turn the Techstream on.

(d) For Seat Belt Motor (Pre-Collision):

(1) Insert the tongue plate into the buckle.

(2) Enter the following menus: Body Electrical / Pre-Collision / Active Test.

(e) For PCS Indicator Light (Combination Meter):

Enter the following menus: Body Electrical / Combination Meter / Active Test.

(f) Perform Active Test according to the display on the tester.

HINT
The engine switch must be turned on to proceed with the Active Test using the tester.
