Quick answer

C0000 is cited in Chevrolet bulletin 13-08-116-001 revisions as a code that may appear with erratic electric power-steering assist. The same bulletin lists inability to relearn the tire-pressure monitoring system (TPM) and, for hybrids, reduced-propulsion-power and service-high-voltage-charging-system messages among possible concerns. The bulletin directs normal SI diagnostics first; if no root cause is found, it indicates checking for a plugged-in device. A vehicle-specific diagnosis is required.

This page separates verified manufacturer/regulator evidence from supporting material. Unsupported causes, repairs or safety conclusions are not guessed.

1. What does C0000 mean?

C0000 is cited in Chevrolet bulletin 13-08-116-001 revisions as a code that may appear with erratic electric power-steering assist. The same bulletin lists inability to relearn the tire-pressure monitoring system (TPM) and, for hybrids, reduced-propulsion-power and service-high-voltage-charging-system messages among possible concerns. The bulletin directs normal SI diagnostics first; if no root cause is found, it indicates checking for a plugged-in device. A vehicle-specific diagnosis is required.

2. Technical explanation

Verified evidence does not establish a standalone universal definition for C0000. In the cited Chevrolet manufacturer communications, C0000 is listed with U2109, U2107, U2100, and B1325 in connection with potentially erratic electric power-steering boost. The same communications describe a broader group of possible conditions, including a TPM warning with inability to relearn TPM and, specifically for hybrids, reduced propulsion power and a service high voltage charging system message. These conditions are not established as symptoms that will occur on every vehicle with C0000. The bulletin says that, after normal diagnostics in SI fail to identify the root cause, a plugged-in device should be checked.

3. What system is affected?

Electric power steering is the system explicitly associated with C0000 in the verified bulletin evidence. Tire-pressure monitoring and, on hybrids, propulsion/charging messages are also mentioned in the bulletin as possible concerns, but a direct C0000-to-system diagnosis is not established.

4. How serious is this code?

Not yet established by verified evidence. The record lists severity as unknown.

5. Symptoms you may notice

  • Potentially erratic electric power-steering boost, associated in the bulletin with C0000 and U2109, U2107, U2100, and B1325.
  • Service Tire Pressure Monitoring (TPM) system light illuminated and inability to relearn TPM are listed in the bulletin.
  • For hybrids, reduced propulsion power and a Service High Voltage Charging System message are listed in the bulletin.
  • The verified evidence does not establish that any listed condition occurs in every C0000 event.

6. Possible causes

  • If normal SI diagnostics do not identify a root cause, the cited Chevrolet bulletin directs checking for a plugged-in device.
  • Any further cause for an individual C0000 event is not yet established by verified evidence.

7. Can I still drive the vehicle?

Not yet established by verified evidence. The record lists safe-to-drive status as unknown. Because the bulletin associates C0000 with potentially erratic electric power-steering boost, obtain professional assessment if steering assist is abnormal.

8. Can I charge the vehicle?

Not yet established by verified evidence. The record lists safe-to-charge status as unknown. Hybrid charging-system messages are mentioned in the bulletin, but the evidence does not establish charging guidance for every C0000 event.

9. What you can safely do

  • Record all warning messages and diagnostic trouble codes present before service.
  • Follow normal Chevrolet SI diagnostics through a qualified service provider.
  • If normal diagnostics do not identify a cause, have the provider consider the bulletin’s instruction to check for a plugged-in device.
  • Do not attempt high-voltage-system repair.

10. Step-by-step troubleshooting

  1. Perform normal diagnostics in Chevrolet SI, as directed by bulletin 13-08-116-001 revisions.
  2. If no root cause is identified after normal SI diagnostics, check for a plugged-in device as directed by the bulletin.
  3. Not yet established by verified evidence: additional step-by-step diagnostic procedures for C0000.

11. When to contact service

Contact a Chevrolet-qualified service provider for normal SI diagnostics, especially if electric power-steering assist is erratic or hybrid propulsion/charging messages are displayed.

12. What the service center may check

  • Perform normal SI diagnostics.
  • If those diagnostics do not identify the root cause, check for a plugged-in device.
  • Assess the reported concern and all stored diagnostic codes; the bulletin cites U2109, U2107, U2100, B1325, and C0000 together in the electric-power-steering context.

13. Possible repair or resolution

  • Not yet established by verified evidence. The supplied bulletin evidence provides a diagnostic direction but does not establish a specific repair or part replacement for C0000.

The supplied applicability data identifies US Chevrolet Blazer (2011–2024), Bolt EUV (2011–2024), Bolt EV (2011–2024), Equinox (2011–2024), Spark (2011–2024), and Volt (2011–2024), with overlapping year ranges in the data. Exact vehicle applicability should be confirmed by a Chevrolet service provider using the VIN and the applicable bulletin.

19. Frequently asked questions

What does C0000 mean on a Chevrolet?

The supplied verified evidence does not establish a standalone universal definition. Chevrolet bulletin 13-08-116-001 lists C0000 among codes potentially associated with erratic electric power-steering boost.

Can C0000 be caused by a plugged-in device?

The bulletin directs technicians to check for a plugged-in device only after normal SI diagnostics do not identify the root cause. It does not establish that every C0000 event is caused by such a device.

Is C0000 a high-voltage charging fault?

Not necessarily. The bulletin lists a Service High Voltage Charging System message specifically among hybrid concerns, but the verified evidence does not establish that C0000 alone identifies a high-voltage charging fault.

Which codes are cited with C0000?

In the electric-power-steering context, the bulletin cites U2109, U2107, U2100, B1325, and C0000.
