This bulletin applies to 2010-2012 Mazda MX-5 Miata vehicles with VINs lower than JM1NC******226801 (produced before June 22, 2012). Some vehicles may experience a check engine light on with DTC P2096:00 (target A/F feedback system too lean). This is caused by the improper control logic. To correct the problem, the control logic has been changed.

Reboot the IDS to clear memory before reprogramming.

Using IDS 89.03 or later software, reprogram the PCM to the latest calibration.

When performing this procedure, Mazda recommends using the “Power Supply” mode in the battery management system to keep the battery up to capacity. If a different charger is used, make sure it does not exceed 20 amps to avoid damaging the VCM.
