One of the following conditions is met:
- When the IG1 terminal voltage is between 10 and 17.4 V, after
the output of data from the skid control ECU is completed, the sending
operation continues for 5 seconds or more.
- The condition that bus OFF state occurs once or more within
0.1 seconds occurs 10 times in succession (Sent signals cannot be
received).
- When the IG1 terminal voltage is between 10 and 17.4 V, a delay
in receiving data from the yaw rate and acceleration sensor and
steering angle sensor continues for 1 second or more.
- When the IG1 terminal voltage is between 10 and 17.4 V, the
following occurs 10 times in succession.
- The condition that a delay in receiving data from the
yaw rate and acceleration sensor and steering angle sensor
occurs more than once within 5 seconds.
