LEXUS PARKING ASSIST-SENSOR SYSTEM > DATA LIST / ACTIVE TEST

for Preparation Click here

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.

HINT:

Using the intelligent tester 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.

1. Connect the intelligent tester to the DLC3.
   

2. Turn the power switch on (IG).
   

3. Turn the LEXUS parking assist-sensor system on.
   

4. Turn the intelligent tester on.
   

5. Enter the following menus: Body / Clearance Sonar / Data List.
   

6. According to the display on the intelligent tester, read the Data List.

HINT:

Using the intelligent tester 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.

1. Connect the intelligent tester to the DLC3.
   

2. Turn the power switch on (IG).
   

3. Turn the LEXUS parking assist-sensor system on.
   

4. Turn the intelligent tester on.
   

5. Enter the following menus: Body / Clearance Sonar / Active Test.
   

6. According to the display on the intelligent tester, perform the Active Test.
