3. What system is affected?

Brake / body electrical system; the verified communication specifically concerns stoplight-switch-related diagnostics and CAN-bus operation.

4. How serious is this code?

Unknown. The verified evidence does not assign a severity level.

5. Symptoms you may notice

  • Not yet established by verified evidence.

6. Possible causes

  • Stoplight-switch adjustment is identified as an item to check before following the Service Manual diagnostic tree.
  • CAN-bus line operation is identified as an essential initial check for electrical concerns.
  • A specific root cause for C1000 is not yet established by verified evidence.

7. Can I still drive the vehicle?

Unknown. The verified evidence does not establish whether driving is safe with C1000.

8. Can I charge the vehicle?

  • Do not perform high-voltage repair work based on this code.

10. Step-by-step troubleshooting

  1. Check CAN-bus line operation. The official communication describes this as essential and the first step for electrical concerns.
  2. Check stoplight-switch adjustment.
  3. After those checks, follow the relevant DTC diagnostic tree in the Service Manual.

11. When to contact service

Service evaluation is appropriate because the supplied official communication directs use of the applicable Service Manual diagnostic tree after the specified preliminary checks. Whether service is mandatory is not established by verified evidence.

12. What the service center may check

  • CAN-bus line operation.
  • Stoplight-switch adjustment.
  • The relevant Service Manual DTC diagnostic tree after the preliminary checks.

13. Possible repair or resolution

  • Not yet established by verified evidence. The supplied communication provides preliminary diagnostic checks but does not provide a verified repair resolution for C1000.
