Missing Fuse?

This bulletin applies to 2013-2019 Mazda CX-5, 2016-2019 CX-3, MX-5 and CX-9 and 2014-2019 Mazda6 and Mazda3 vehicles. Some vehicles may experience the check engine light on with DTC P2610 and P2507 stored in memory after engine start with the 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 this (no warning light illuminated), 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 3 or more times after a short duration of engine off (less than 15 seconds) with the room fuse removed. The odometer will display “F0-002” during a transport mode with the room fuse removed. Transport mode is cancelled when the room fuse is installed.

If the room fuse has been removed, install a good 15A fuse with ignition off. Start the engine and let it run for at least 10 seconds, the shut the engine off. Start the engine again and verify that the check engine light is not illuminated, then shut off the engine. Clear DTCs from memory using IDS.

Note the location of the 15A room fuse (see “A” at lower left of this illustration).
