A 2015 BMW i3 REX displayed a series of error codes after a diagnostic scan using a Bluetooth OBDII adapter and the BimmerGeeks ProTool app. Understanding these codes is crucial for effective troubleshooting and repair. This article breaks down the specific error codes encountered and provides insight into potential underlying issues. Leveraging Bluetooth OBDII technology in Honolulu allows for convenient and cost-effective diagnostics for BMW owners.
Understanding BMW i3 REX Error Codes
The following error codes were retrieved from the vehicle on November 14, 2021:
High-Voltage Electrical System Errors
- EME/RLM1R (Electric Motor Electronics/Rear Left Motor 1 Rear):
- 22280F: High-voltage electrical system: Isolation resistance below fault threshold value.
- 222814: High-voltage electrical system: Insulation resistance below warning threshold.
- SME (System Management Electronics):
- 21F0E3: High-voltage electrical system: Insulation resistance below threshold (fault).
- 21F0E4: High-voltage electrical system: Insulation resistance below warning threshold.
These codes indicate a potential issue with the high-voltage battery system’s insulation. This could be caused by damage to wiring, connectors, or the battery itself. Ignoring these errors could lead to further damage and potentially dangerous situations. Professional diagnosis is crucial.
Camera System Error
- KAFAS (Driver Assistance Systems):
- 800AC5: Heating camera-based driver support system: Short circuit to positive terminal or open circuit.
This error suggests a problem with the heating element of the camera used for driver assistance features. This could be due to a faulty heating element, wiring issue, or a problem with the camera module itself. This may impact the functionality of features like lane departure warning or adaptive cruise control.
Utilizing Bluetooth OBDII in Honolulu for BMW Diagnostics
