Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Theory Of Operation
The Central ADAS Decision Module 2 (CADM2) monitors each Radar module and will set a DTC for the following conditions:
- Shorted to ground, voltage or open
- Over voltage
- Under voltage
- Incorrect component installed
- Internal hardware or software failure
- Over temperature
- Misalignment
- Obstructed field of view
- Missing or incomplete calibration
- Signal invalid
- Missing message
- Loss of communication
- Implausible data
The Radar components are split into 2 groups, front and rear, and are based on their layout position.
| DTC Prefix | Radar DTC Name | Radar Location |
|---|---|---|
| C00C0 | Front Radar Module "A" | Front Left Mid Range Radar |
| C00C1 | Front Radar Module "B" | Front Long Range Radar |
| C00C4 | Rear Radar Module "A" | Rear Left Mid Range Radar |
For an in-depth explanation of the Long and Mid Range Radar and the Central Driver Assist system refer to the Service Information.
