Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
2021 Mazda MX-5 Miata Club, Automatic TransFACTORY OEM SERVICE PROCEDURE
Using The M-MDS
NOTE:
- PIDs for the following parts are not available on this model. Go to the appropriate part inspection information.
- Intake CMP sensor and exhaust CMP sensor (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION .)
- Main relay (See RELAY INSPECTION .)
- Connect the M-MDS to the DLC-2.
- Switch the ignition ON (engine off).
- Measure the PID value.
- If PID value is not within the specification, follow the instructions in action column.
NOTE:- The PID/DATA MONITOR function monitors the calculated value of the input/output signals in the PCM. Therefore, an output device malfunction is not directly indicated as a malfunction of the monitored value for the output device. If a monitored value of an output device is out of specification, inspect the monitored value of the input device related to the output control.
- The simulation items that are used in the engine control system operation inspection are as follows.
- ACCS, ARPMDES, EVAPCP, EVAPCV, FAN_DUTY, FAN1, FP, INJ_1, INJ_2, INJ_3, INJ_4, OIL_P_SOL

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
