Data Monitor/Active Test

Data monitor

NOTE: Using the SSM4 to read the [Data monitor] 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 monitor] information early in troubleshooting is one way to save diagnostic time.

CAUTION: 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 SSM4 to the DLC3.
Turn the ignition switch to ON.
Turn the SSM4 on.
Enter the following menus: [Body Control] →[Data monitor]
Enter the following menus: [Engine Control System] →[Data monitor]
Read the [Data monitor] according to the display on the SSM4.

Active test

NOTE: Using the SSM4 to perform [Active Test] 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 Test] early in troubleshooting is one way to save diagnostic time. [Data monitor] information can be displayed while performing [Active Test].

Connect the SSM4 to the DLC3.
Turn the ignition switch to ON.
Turn the SSM4 on.
Enter the following menus: [Body Control] →[Active Test]
According to the display on the SSM4, perform the [Active Test].
