1. What does C0765 mean?

C0765 is documented by Chevrolet bulletins in connection with remote-control door-lock receiver, key-fob/passive-entry, and tire-pressure-monitor concerns. The supplied evidence does not establish driving or charging safety.

2. Technical explanation

The verified diagnostic title/meaning is “R/CON DR LK 13595511 1 Warranty I.” Chevrolet bulletin 16-NA-396 identifies C0765, including symptom :29 “Too Few Pulses” in one version, with tire-pressure-monitor indications and states that the condition may be due to an issue internal to the Remote Control Door Lock Receiver. Separate PIC5650 bulletin versions list C0765 among codes that can appear with radio-frequency-related concerns, including possible radio-frequency interference from aftermarket devices.

3. What system is affected?

Verified evidence associates this code with the Remote Control Door Lock Receiver and with radio-frequency-operated functions, including remote keyless entry/passive entry and tire pressure monitoring.

4. How serious is this code?

Unknown. Not yet established by verified evidence.

5. Symptoms you may notice

  • Tire pressure monitor indicator or Service Tire Pressure Monitor message.
  • Poor or no remote keyless entry range.
  • Keyless or passive entry/start inoperative.
  • No Fob Detected message.
  • Passive entry may not respond to lock/unlock commands.
  • Key-fob lock, unlock, hatch/trunk, remote start, and panic functions may be inoperative.
  • Intermittent no crank, no start, or start-and-stall concerns are listed in PIC5650 bulletins.
  • Security/Theft light or message.

6. Possible causes

  • An issue internal to the Remote Control Door Lock Receiver, as described in Chevrolet bulletin 16-NA-396 for the specified concern pattern.
  • Radio-frequency interference from some aftermarket devices, as described in PIC5650 bulletins.

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

  • Do not attempt high-voltage repairs; the supplied evidence does not identify a high-voltage component or repair procedure.
  • Record any messages, affected key-fob functions, and whether the tire-pressure-monitor indicator is illuminated.
  • If the vehicle has keyless/passive start and displays No Fob Detected, PIC5650 states that it will start with the fob placed in the fob pocket.
  • Arrange diagnosis by a Chevrolet service provider if the concern persists.

10. Step-by-step troubleshooting

  1. Check for the documented symptom pattern: C0765 with tire-pressure-monitor, remote keyless entry, passive-entry/start, or No Fob Detected concerns.
  2. Have a service provider consider the applicable PIC5650 guidance regarding possible radio-frequency interference from aftermarket devices.
  3. For the 16-NA-396 concern pattern, have a service provider evaluate the Remote Control Door Lock Receiver.

11. When to contact service

Contact a Chevrolet service provider for diagnosis, particularly if remote functions, passive entry/start, or tire-pressure-monitor warnings are present. The evidence supports receiver evaluation and consideration of radio-frequency interference, but does not establish a universal repair for every C0765 occurrence.

12. What the service center may check

  • Confirm the stored DTC(s) and whether C0765 is accompanied by C0750, C0755, C0760, C0775, B3055, B3060, or B3935.
  • Check whether the vehicle matches the symptom pattern described in bulletin 16-NA-396.
  • Evaluate the Remote Control Door Lock Receiver when the 16-NA-396 condition pattern is present.
  • Consider possible radio-frequency interference from aftermarket devices, consistent with PIC5650 guidance.

13. Possible repair or resolution

  • For vehicles meeting the 16-NA-396 concern pattern, Chevrolet’s bulletin directs replacement of the Remote Control Door Lock Receiver, with reference to the service information procedure.
  • No other repair resolution is established by the supplied verified evidence.

14. Affected vehicles

15. Related TSBs / service bulletins

  • Chevrolet bulletin 16-NA-396: identifies C0765 with specified remote-function and tire-pressure-monitor concerns; states the cause may be internal to the Remote Control Door Lock Receiver and directs receiver replacement for that condition pattern.
  • Chevrolet PIC5650 revisions C through L: list C0765 among codes associated with intermittent starting, security, key-fob, passive-entry/start, and tire-pressure-monitor concerns; note that some aftermarket devices can cause radio-frequency interference.

19. Frequently asked questions

What does C0765 mean?

The verified diagnostic title is “R/CON DR LK 13595511 1 Warranty I.” Chevrolet bulletins associate it with the Remote Control Door Lock Receiver and, in specified cases, a “Too Few Pulses” symptom.

Can radio-frequency interference cause C0765-related concerns?

PIC5650 states that some aftermarket devices can cause radio-frequency interference that may affect the listed concerns and codes, including C0765.

Does C0765 prove the receiver has failed?

No. Bulletin 16-NA-396 says the specified symptom pattern may be due to an internal Remote Control Door Lock Receiver issue. PIC5650 also identifies potential radio-frequency interference. A diagnosis is required.

Can I drive or charge with C0765?

Not yet established by verified evidence.
