DESCRIPTION
Some vehicles may experience a lack of engine power/rough idling and the check engine light on with one or more of the misfire related DTCs of P0300:00, P0301:00, P0302:00, P0303:00 and P0304:00. This concern may be caused by an internal failure of the ignition coil(s) due to a high difference between cold and warm ambient temperatures. The production method of the ignition coil has been changed to eliminate this concern.
NOTE: The ignition coils are supplied from two different vendors, YUMEBISHI and MITSUBISHI. This concern only occurs on YUMEBISHI- produced ignition coil.
To distinguish between YUMEBISHI and MITSUBISHI ignition coils, look at their lot numbers (A). YUMEBISHI have 4 digit lot numbers and MITSUBISHI have 5 digit lot numbers as shown.

Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
- Verify the customer concern and the misfire related DTC(s) exists using the M-MDS.
- Switch the two ignition coils of the cylinder with a misfire (identified by the misfire DTC) and a cylinder without misfire.
- If the misfire transfers to the other cylinder, the ignition coil is defective. Go to next step.
- If the misfire does not transfer, a different cause such as malfunction of the wiring harness, spark plug etc. is possible. In this case, this TSB is not applicable. Perform further diagnosis according to the workshop manual.
- Replace the defective ignition coil(s) with modified one(s) according to the workshop manual (section 01-18). CX-5: IGNITION COIL/ION SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5]. Mazda3: IGNITION COIL/ION SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5]. Mazda6: IGNITION COIL/ION SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 2.5].
- Check if any of the other non-defective coils are YUMEBISHI-produced and made before lot number 6328 (March 28, 2016 production). If any were made before this date, replace them with modified one(s) as well.
- Verify the repair
