DTC DETECTION CONDITION AND TROUBLE AREA

DTC No. DTC Detection Condition Trouble Area
U0073/94 When one of following conditions is met:
  1. With the IG1 terminal voltage 10 V or more, after the output of data from the skid control ECU is completed, the sending continues for 5 seconds or more.
  2. With the IG1 terminal voltage 10 V 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.)
  3. With the IG1 terminal voltage 10 V or more, a delay in receiving data from the yaw rate and acceleration sensor and steering angle sensor continues for 1 second or more.
  4. With the IG1 terminal voltage 10 V or more, the condition that a delay in receiving data from the yaw rate and acceleration sensor and the steering angle sensor occurs more than once within 5 seconds occurs 10 times in succession within 60 seconds.
CAN communication system
U0100/65 When either condition below is met:
  1. With the IG1 terminal voltage 10 V or more and the vehicle speed 15 km/h (9 mph) or more, data cannot be sent to the ECM for 2 seconds or more.
  2. With the IG1 terminal voltage 10 V or more and the vehicle speed 15 km/h (9 mph) or more for 2 seconds or more.
CAN communication system (Skid control ECU to ECM)
U0123/62 When either condition below is met:
  1. With the IG1 terminal voltage 10 V or more, data from the acceleration sensor cannot be received for 1 second or more.
  2. With the IG1 terminal voltage 10 V or more, the following occurs 10 times in succession within 60 seconds.
    1. The condition that data from the acceleration sensor cannot be received occurs once or more within 5 seconds.
CAN communication system (Skid control ECU to yaw rate and acceleration sensor)
U0124/95 When either condition below is met:
  1. With the IG1 terminal voltage 10 V or more, data from the acceleration sensor cannot be received for 1 second or more.
  2. With the IG1 terminal voltage 10 V or more, the following occurs 10 times in succession within 60 seconds.
    1. The condition that data from the acceleration sensor cannot be received occurs once or more within 5 seconds.
CAN communication system (Skid control ECU to yaw rate and acceleration sensor)
U0126/63 When either of following conditions detected:
  1. When IG1 terminal voltage 10 V or more, data from steering sensor cannot be received for 1 second or more.
  2. When IG1 terminal voltage 10 V or more, following condition occurs 10 times in succession.
