Powertrain Control Module: Notes

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2002 Mazda Tribute, 2002 Mazda Protege5, 2002 Mazda Protege, 2002 Mazda Millenia, and 2002 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Some models may be equipped with an immobilizer system. This system can be identified by the ignition key blanks. If the key ring hole on blank has no metal exposed, vehicle is equipped with system. The immobilizer system requires using a CODE WORD for reprogramming keys to PCM. The CODE WORD is only available to the dealer from Mazda.

CAUTION: If PCM or PCM and Immobilizer control unit are replaced, all keys must be programmed before starting vehicle. If not, damage to PCM will occur.
