*1: Whether the ECU that sends data is functioning or not can be judged by using the Techstream to check
items such as switches or sensors that send signals to the ECU via direct lines.
*2: Although the received contents cannot be checked in the Data List, whether or not the data is received
normally can be checked by observing the combination meter.
*3: The combination meter assembly receives a vehicle speed signal from the brake actuator assembly (skid
control ECU) and sends the signal to other ECUs.
*4: The main body ECU (multiplex network body ECU) receives a driver seat buckle switch signal from the
airbag sensor assembly and sends the signal to other ECUs.
(b) Details of relevant Data List items (Selected system: Engine)
HINT:
U
sing 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:
I
n 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.
