DTC U0073/94 Control Module Communication Bus OFF; DTC U0100/65 Lost Communication with ECM / PCM; DTC U0123/62 Lost Communication with Yaw Rate Sensor Module; DTC U0124/95 Lost Communication with Lateral Acceleration Sensor Module; DTC U0126/63 Lost Communication with Steering Angle Sensor Module: Description

The skid control ECU inputs the signals from the ECM, steering angle sensor, and yaw rate and acceleration sensor via CAN communication system.

DTC DETECTION CONDITION

DTC No. DTC Detecting Condition Trouble Area
U0073/94  When either of the following is detected:
  1. After the output of data from the skid control ECU is completed, the sending continues for 5 seconds or more.
  2. The condition that bus OFF state occurs once or more within 100 ms occurs 10 times in succession. (Sent signals cannot be received.)
 CAN communication system
U0100/65  When either of the following is detected:
  1. With the IG1 terminal voltage 10 V or more and the vehicle speed 9 mph (15 km/h) or more, data cannot be sent to the ECM.
  2. With the IG1 terminal voltage 10 V or more and the vehicle speed 9 mph (15 km/h) or more, either of the following occurs 10 times in succession.
    • The condition that data cannot be sent to the ECM occurs once or more within 5 seconds.
    • The condition that data from the ECM cannot be received occurs once or more within 5 seconds.
 Can communication system (Skid control ECU to ECM)
U0123/62  When either of the following is detected:
  1. With the IG1 terminal voltage 10 V or more, data from the yaw rate 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.
    • The condition that data from the yaw rate 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 of the following is detected:
  1. With the IG1 terminal voltage 9.5 V or more, data from the acceleration sensor cannot be received for 1 second or more.
  2. With the IG1 terminal voltage 9.5 V or more, the following occurs 10 times in succession.
    • 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 the following is detected:
  1. With the IG1 terminal voltage 10 V or more, data from the steering 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.
    • The condition that data from the steering angle sensor cannot be received occurs once or more within 5 seconds.
