Diagnosis Procedure with Self-Diagnosis Function (Without CONSULT- I I )NGS000EL
DESCRIPTION
If a malfunction is detected in the system, the RAS warning lamp turns on and indicates the malfunction. At
that time, fail-safe activates, and then stops the function.
SELF-DIAGNOSIS PROCEDURE
1. Start engine.
2. Turn steering wheel left and right at 20
or more and 5 times or more within 10 seconds. And then depress
the service brake 5 times or more.
3. RAS warning lamp blinks (displays normal/malfunction).
SELF-DIAGNOSIS DISPLAY
RAS warning lamp blinks and displays the self-diagnostic results.
Only DTCs are displayed as the pattern shown in the figure, and
then repeat the display.
If all items are normal, RAS warning lamp blinks at 4 Hz cycle.
SELF-DIAGNOSIS DISPLAY ITEMS
HOW TO ERASE SELF-DIAGNOSIS
If there is the history data for when the fail-safe has activated in the past, erase the memory with CONSULT-II.
Refer to STC-29, "
How to Erase Self-Diagnostic Results" .
CAN CommunicationNGS000EM
SYSTEM DESCRIPTION
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only. Refer to LAN-34, "
CAN
Communication Unit" .
