This bulletin concerns some 2014-2021 Mazda6, 2013-2021 CX-5, 2014-2018 Mazda3, 2016-2021 CX-3, 2016-2021 MX-5 and 2016-2021 CX-9 vehicles.

Some 2014-2021 Mazda6, 2013-2021 CX-5, 2014-2018 Mazda3, 2016-2021 CX-3, 2016-2021 MX-5 and 2016-2021 CX-9 vehicles may experience the check engine light on with diagnostic trouble code (DTC) P2610 and P2507 stored in memory after engine start and room fuse 15A removed.

P2610:00...instrument cluster internal engine off timer performance problem.

P2507:00....PCM battery voltage low input.

As a past malfunction, the customer will see no warning light, but the DTC may be found during service. 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.

REPAIR

Verify DTC P2610 and P2507 are stored in powertrain control module (PCM) memory.

Install room fuse 15A 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.
