DTC Detecting Condition |
Trouble Area |
| U0073/94 |
When either of the following is detected:
- After the output of data from the skid control ECU is completed, the sending continues for 5 seconds or more.
- The condition that bus OFF state occurs once or more within 100 ms occurs 10 times in succession. (Sent signals cannot be received.)
