1. What does C2702 mean?
C2702 is referenced in Hyundai TSB 19-BE-011H-1 for vehicles equipped with Blind Spot Detection (BSD) or Blind-Spot Collision Warning (BCW). The supplied evidence does not establish a complete diagnostic definition for C2702.
2. Technical explanation
NHTSA-hosted Hyundai manufacturer communication 19-BE-011H-1 discusses BSD/BCW radar sensor angle measurement. For C2702/C2703, it states that if a BSD/BCW sensor is confirmed damaged by external impact or a collision accident, sensor replacement is not covered under warranty. It also states that if the bracket is confirmed damaged, only the bracket should be replaced, with down-level replacement-part information referenced in TSB 18-BE-005-1.
3. What system is affected?
Blind Spot Detection (BSD) or Blind-Spot Collision Warning (BCW) system.
4. How serious is this code?
Not yet established by verified evidence.
5. Symptoms you may notice
- Not yet established by verified evidence.
6. Possible causes
- Confirmed external-impact or collision damage to a BSD/BCW sensor is specifically addressed by the supplied Hyundai TSB.
- Confirmed damage to a BSD/BCW sensor bracket is specifically addressed by the supplied Hyundai TSB.
- No further causes are established by verified evidence.
7. Can I still drive the vehicle?
Not yet established by verified evidence.
8. Can I charge the vehicle?
Not yet established by verified evidence.
9. What you can safely do
- Arrange diagnosis by a Hyundai service provider or other qualified vehicle service professional.
- If there has been an impact or collision near a BSD/BCW sensor area, report that history to the service provider.
- Do not assume that a sensor must be replaced: the supplied TSB distinguishes confirmed sensor damage from confirmed bracket damage.
10. Step-by-step troubleshooting
- The supplied Hyundai TSB identifies BSD/BCW radar sensor angle measurement as part of the relevant service procedure.
- Have the BSD/BCW sensor and its bracket inspected for confirmed external-impact or collision damage.
- Not yet established by verified evidence: a complete step-by-step diagnostic procedure, wiring checks, scan-tool data interpretation, or calibration specifications for C2702.
11. When to contact service
Service evaluation is appropriate because Hyundai TSB 19-BE-011H-1 provides a BSD/BCW radar-sensor angle-measurement procedure and specific repair direction when sensor or bracket damage is confirmed.
12. What the service center may check
- Inspect the BSD/BCW sensor(s) for confirmed damage from external impact or collision accident.
- Inspect the BSD/BCW sensor bracket(s) for confirmed damage.
- Perform BSD/BCW radar sensor angle measurement using the tool and procedure applicable under Hyundai TSB 19-BE-011H-1.
13. Possible repair or resolution
- If the BSD/BCW sensor is confirmed damaged by external impact or collision accident, the TSB addresses sensor replacement; such replacement is stated not to be covered under warranty in that circumstance.
- If the bracket is confirmed damaged in a C2702/C2703 case, Hyundai instructs that only the bracket be replaced.
- TSB 18-BE-005-1 is referenced for available down-level BSD/BCW replacement parts.
