PCM Replacement

WARNING: This page is about a different car, the 2005 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

PCM must be replaced by performing "Programmable Module Installation Procedure." (See PCM REPLACEMENT [L3] .) (See PCM REPLACEMENT [AJ] .)
After PCM replacement, and programmable module installation has been performed, refer to the procedure for "KEY REPLACEMENT ", and perform key programming. (See KEY REPLACEMENT .)

NOTE:

To start the engine, two or more keys need to be programmed.
