NETWORKING: CAN COMMUNICATION SYSTEM: DIAGNOSIS SYSTEM - (Continued)

11. DATA SENDING/RECEIVING TABLE

(a) Data sending/receiving table

HINT
If Data List items related to sent/received data are not displayed properly, the part for which communication is interrupted can be determined using the table below.

















*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 booster with master cylinder assembly (skid control ECU)*1 and sends the signal to other ECUs.

(b) Details of relevant Data List items (Selected system: Hybrid Control)

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 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.
