1. What does C0750 mean?

C0750 is identified by Chevrolet as “R/CON DR.” Verified GM communications associate it with Remote Control Door Lock Receiver/RF-related concerns and, in one bulletin, a tire-pressure-monitor fault with symptom :29 “Too Few Pulses.”

2. Technical explanation

Verified Chevrolet/GM communications link C0750 to the Remote Control Door Lock Receiver and radio-frequency-related vehicle functions. Bulletin 16-NA-396 states that, when C0750/C0755/C0760/C0765 occur with the specified related symptoms, the cause may be an issue internal to the Remote Control Door Lock Receiver. Separate PIC5650 revisions state that radio-frequency interference from some aftermarket devices can produce a group of concerns that includes C0750. A stored C0750 alone does not establish which condition is present.

3. What system is affected?

Remote Control Door Lock Receiver / radio-frequency vehicle functions; tire-pressure-monitor messages may also occur in the documented condition.

4. How serious is this code?

Not yet established by verified evidence.

5. Symptoms you may notice

  • Tire pressure monitor indicator illuminated or a Service Tire Pressure Monitor message.
  • Poor or no remote keyless-entry range.
  • Keyless/passive entry or start inoperative.
  • No Fob Detected message.
  • Security/theft light or message.
  • Intermittent no crank, no start, or start-and-stall reports in the PIC5650 communications.
  • Push-button start may not respond, with a No Remote Detected message.
  • Remote lock, unlock, hatch/trunk, remote start, and panic functions may be inoperative.

6. Possible causes

  • An issue internal to the Remote Control Door Lock Receiver is identified in GM bulletin 16-NA-396 for the specified combination of symptoms and codes.
  • Radio-frequency interference from some aftermarket devices is identified in PIC5650 communications as a possible contributor to the listed concerns.
  • Not yet established by verified evidence for any individual vehicle without diagnosis.

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

  • Record all warning messages and whether remote, passive-entry, start, or tire-pressure-monitor functions are affected.
  • Have a qualified Chevrolet/GM service facility retrieve all diagnostic trouble codes and evaluate the vehicle using applicable service information.
  • Do not attempt high-voltage system repairs; the supplied evidence does not identify C0750 as a high-voltage fault.

10. Step-by-step troubleshooting

  1. Confirm whether C0750 is present with C0755, C0760, C0765, B3055, B3060, B3935, or C0775.
  2. For vehicles equipped with keyless/passive start, the PIC5650 communications state that the vehicle will start if the fob is placed in the fob pocket.
  3. A qualified technician should consider the documented possibility of radio-frequency interference from aftermarket devices and the documented receiver-related condition, as applicable.

11. When to contact service

Arrange Chevrolet/GM service if the code is current, remote/passive-entry functions fail, a No Fob Detected message appears, starting is affected, or the tire-pressure-monitor warning/message is present.

12. What the service center may check

  • Retrieve and document all current and history DTCs, including the codes specifically listed in applicable GM communications.
  • Verify the reported remote keyless-entry, passive-entry, push-button-start, and tire-pressure-monitor symptoms.
  • Evaluate for the documented possibility of aftermarket-device radio-frequency interference.
  • Where the conditions of bulletin 16-NA-396 are met, evaluate the Remote Control Door Lock Receiver using GM service information.

13. Possible repair or resolution

  • GM bulletin 16-NA-396 directs replacement of the Remote Control Door Lock Receiver when the bulletin’s specified concern is encountered.
  • No universal repair can be established from C0750 alone.

19. Frequently asked questions

What does Chevrolet C0750 mean?

The verified diagnostic title and meaning are “R/CON DR.” GM communications associate the code with the Remote Control Door Lock Receiver and related radio-frequency functions.

Can radio-frequency interference cause C0750-related concerns?

Yes. PIC5650 communications state that some aftermarket devices can cause radio-frequency interference associated with listed concerns that include C0750.

Does C0750 always require receiver replacement?

No. Bulletin 16-NA-396 directs Remote Control Door Lock Receiver replacement when its specified combination of concerns is encountered. The supplied evidence does not establish receiver replacement for every stored C0750.

Can the vehicle start if No Fob Detected is displayed?

For vehicles equipped with keyless/passive start, the PIC5650 communications state that the vehicle will start if the fob is placed in the fob pocket.
