Error Handling
LIN BUS Off error case
| Section | Error recognition condition | Error releasing condition |
|---|---|---|
| Initial Routine | LIN BUS OFF is sensed once | Error is not released in initial mode. |
| Normal Routine | LIN BUS OFF is sensed four times in a row | The fault is released when BCM or LIN Master senses LIN BUS ON four times in a row in normal mode |
- Remark:
- When counting fault, output message or signal should be transmitted in the Last Valid value.
- If an Error occurs in initial mode, fault buzzer (BCM) and fault display (Cluster) are operated.
- If an Error occurs in normal mode, fault is displayed only on Cluster without buzzer.
Sensor fault (LIN Msg: 0x08)
| Section | Error recognition condition | Error releasing condition |
|---|---|---|
| Initial Routine | Sensor fault Message is sensed once | Error is not released in initial mode. |
| Normal Routine | Sensor fauly Message is sensed four times in a row | The fault is released when BCM or LIN Master senses LIN BUS ON four times in a row in normal mode |
- When displaying fault, RCR/RCL indicator is displayed individually.
- Remark:
- When counting fault, output message or signal should be transmitted in the Last Valid value.
- If an Error occurs in initial mode, fault buzzer (BCM) and fault display (Cluster) are operated.
- If an Error occurs in normal mode, fault is displayed only on Cluster without buzzer.
- If an Error occurs in direct condition, the sensors send the same status of error as in indirect condition.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
