Some 2013-2021 Mazda CX-5, 2014-2021 Mazda6 and 2014-2018 Mazda3 vehicles may experience a MIL on with DTC P2610 (instrument cluster internal engine off timer performance problem) and P2507 (PCM battery voltage low input) stored in memory after engine start and room fuse 15A is removed.

As a past malfunction, you may not notice a warning light, but the DTC may be found during vehicle service. P2507 in this situation is only applicable on 2016 and later models. This is caused by the engine being started three or more times after a short duration of engine off (less than 15 seconds) with the room fuse removed.

Verify P2610 and P2507 are stored in PCM memory. Install room fuse 51A with ignition off. Start the engine and let it run for at least 10 seconds, then stop the engine. Start the engine again and verify that the check engine light is not illuminated, then stop the engine. Clear the DTCs from PCM memory using IDS. Verify that no other DTCs are stored.
