DTC U0073/51: Control Module Communication Bus OFF; DTC U0100/53: Lost Communication with ECM/PCM; DTC U0124/55: Lost Communication with Lateral Acceleration Sensor Module; DTC U0129/52: Lost Communication with Brake System Control Module: Description
The parking brake ECU assembly uses CAN communication with the ECM, acceleration sensor (yaw rate sensor) and skid control ECU (brake actuator assembly).
| DTC No. | Detection Condition | Trouble Area |
|---|---|---|
| U0073/51 | With the engine switch on (IG), the bus is off (communication with other ECUs is not possible) for 2 seconds. | CAN communication system |
| U0100/53 | With the engine switch on (IG) and the vehicle being driven at 15 km/h (9 mph) or more, the parking brake ECU assembly cannot receive signals from the ECM for approximately 1 second or 10 seconds (malfunction duration differs depending on the signal). |
|
| U0124/55 | With the engine switch on (IG), the parking brake ECU assembly cannot receive signals from the acceleration sensor for approximately 1 second. |
|
| U0129/52 | With the engine switch on (IG), the parking brake ECU assembly cannot receive signals from the skid control ECU for approximately 1 second or 10 seconds (malfunction duration differs depending on the signal). |
