RX8 DSC dirty little secret

August 3, 2009 · Print This Article

The RX-8 has DSC enabled by default.

Mazda put in a disable button that you can depress for 2 seconds to disable some of DSC’s features.

What isn’t in the manual is a secret mode that can be activated by holding down on DSC even longer than 2 seconds. You’ll know when it activates because an error light will turn on in your dash. That’s Mazda’s way of avoiding lawyers - DSC “malfunctioned”

What this “DSC error” does is remove ALL DSC functionality.

Please be warned that according to the Service Highlights manual, code C1093 (DSC OFF switch system) is logged. The DSC hydraulic unit/control module has a non-volatile memory that cannot be cleared even if the cars battery is removed.
Rumor is that disabling DSC will yield better gas mileage. There has been no concrete proof of this, and more often than not, users who believe this end to report later that they wrapped their car around a tree. Go figure.

    So it can easily be re-enabled via the button right?

    Yeah, you are a load of CRAP…RX-8 owners already know that if you HOLD the DSC button for about 7 seconds is will TOTALLY Disable the DSC, you will get dash warning light (normal), DSC will automatically re-engage the next time you turn car off/ON. As far as Mazda avoiding “lawyers”, another load of American CRAP..bunch of paranoid fools…the only “dirty” one is the author.
