*1: Fail-safe operation does not activate. A signal from control unit suspends TCS and ABS control operation. Brakes operate conven-
tionally. After specified power supply voltage resumes, TCS OFF and SLIP indicator and ABS warning lamp go out, allowing for TCS
and ABS control operation.
*2: If a wheel or wheels spin on bad or slippery road surfaces for a period of approximately 10 to 80 seconds, the ABS warning lamp
and the TCS OFF indicator lamp light. But this is not a malfunction. When the ignition switch is turned “ON” after a shorted wheel sen-
sor circuit has been repaired, the ABS warning lamp and the TCS OFF indicator lamp light. Drive the vehicle at about 30 km/h (19 MPH)
or more to ensure these lamps go out within 1 minute.
*3: TCS control stops due to fail safe operation, however ABS keeps operation.
*4: For more detail, refer to BR-73.
*5: For more detail, refer to BR-74.

BR-58
NOTE:
When a system part have electric malfunction, ABS warning lamp is illuminated by fail-safe function. According to malfunctioning
condition, both ABS and EBD system become in following conditions.
1)
ABS is not operated. EBD is operated.
2)
Both ABS and EBD are operated. (Same condition as the vehicle without ABS and EBD)
On the condition 1), some sound for ABS system self-diagnosis can be heard same as usual, when key switch is turned ON or first
starting.

System Description
NHBR0209
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
electronic 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 wir-
ing. Each control unit transmits/receives data but selectively reads required data only. Refer to EL-448, “Sys-
tem Description”.
