What this code means
P2610 may mean the PCM is detecting a problem with its ignition-off internal timer logic.
What the vehicle may do
- The vehicle may turn on a warning light.
- The code may be stored without an obvious drivability complaint.
- The vehicle can show symptoms related to ignition-state tracking or module wake/sleep behavior.
Possible fault areas
- Possible PCM monitoring logic issue.
- Possible ignition-off timing information concern.
- Possible power, ground, or ignition-related input concern.
Diagnostic path
Opening context
This episode is for P2610 on a 2020 to 2025 Honda CR-V Hybrid with the 2.0 hybrid system. In plain language, this code means the PCM may be seeing a problem with its ignition-off internal timer logic. The vehicle may have a warning light, may store the code without an obvious drivability complaint, or can show behavior that points back to ignition-state tracking. The broad areas to keep in mind are possible PCM monitoring logic, ignition-off timing information, and the power, ground, or ignition-related inputs the module depends on.
Start the diagnostic path
Before getting into the code path, start with the basic system checks and follow a structured diagnostic approach. For this code, the diagnostic path begins by turning the vehicle to the ON mode. From there, continue methodically. If the earlier checks point somewhere specific, follow that path; if the return point is unclear, pause, recheck the earlier diagnostic path, and avoid guessing.
Diagnostic logic
The logic behind P2610 is internal to the PCM’s assessment of ignition-off timing. If the PCM determines that this internal timing function is abnormal, it stores the DTC. Because this is a plausibility-style fault, do not jump straight to a part. Keep the diagnosis focused on whether the module’s ignition-state information and supporting electrical conditions make sense before drawing a conclusion.
Verification and takeaway
After the diagnostic work is complete, verify the repair separately from the testing path and confirm the code stays gone. The key takeaway: P2610 is about the PCM seeing an abnormal ignition-off internal timer condition, so stay organized, confirm the basics, and do not guess past the diagnostic path.

Final check
P2610 should be handled as a structured plausibility diagnosis, with the basics checked first and the final repair confirmed afterward.
