Fuse Out During Transport?

This bulletin applies to 2013-2017 Mazda CX-5, 2014-2017 Mazda6, 2014-2017 Mazda3, 2016-2017 CX-3, 2016-2017 MX-5 and 2016-2017 CX-9 vehicles. Some vehicles may experience the check engine light on with DTC P2610 and P2507 stored in memory after engine start, with room fuse 15A removed.

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

P2507..........PCM battery voltage low output

As a past malfunction, the customer will not notice it (possibly no warning light on), but the DTC may be found during service. P2507 in this situation is only applicable to 2016 and later models. This is caused by the engine being started 3 or more times after a short duration of engine off (less than 15 seconds) with the room fuse removed. Verify that DTC P2610 and P2507 are stored in 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 and verify that the check engine light is off, then stop the engine. Clear DTCs from PCM memory.

Note the location of room fuse 15A.
