DTC Code DTC Detection Conditions Trouble Area
U0073 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.
 CAN communication system
U0100 Either condition is met:
  • When the IG1 terminal voltage is between 10 and 17.4 V and the vehicle speed 15 km/h (9 mph) or more, data cannot be sent to the ECM for 2 seconds or more.
