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 U0126/63 Lost Communication with Steering Angle Sensor Module: Description

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

DTC DETECTING CONDITION CHART

DTC No.	DTC Detection Condition	Trouble Area
U0073/94	When either of the following is detected: Bus OFF state continues for 300 msec. The ECU detects that it cannot send a signal.	CAN communication system
U0100/65	When either of the following is detected: At a vehicle speed of 4 mph (6 km/h) or more, the skid control ECU receives data that is out of range from the engine. At a vehicle speed of 4 mph (6 km/h) or more, the skid control ECU receives abnormal data from the engine (5 cycles).	CAN communication system (Skid control ECU to ECM)
U0123/62	When any r of the following is detected: The skid control ECU receives an abnormal signal from the yaw rate sensor (5 cycles). The skid control ECU receives a signal that has a shorter message than normal. The skid control ECU cannot receive a signal from the yaw rate sensor.	CAN communication system (Skid control ECU to yaw rate and acceleration sensor)
U0126/63	When any of the following is detected: The skid control ECU receives an abnormal signal from the steering angle sensor (5 cycles). The skid control ECU receives a signal that has a shorter message than normal. The skid control ECU cannot receive a signal from the steering angle sensor.	CAN communication system (Skid control ECU to steering angle sensor)
