Engine Control System [MZI-3.7]: Other Mazda CX-9 I рестайлинг

PCM CONFIGURATION [MZI-3.7]

Note. When performing the PCM configuration and PCM reprogramming simultaneously, perform the PCM configuration and then perform the PCM reprogramming after the session has been completed. If the PCM reprogramming is performed with the session not completed, it may result in improper operation of the PCM.

Scheme 43
