Brake Switch Inspection

WARNING: This page is about a different car, the 2017 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.

Inspect the brake switch with it installed to the brake pedal, otherwise the brake switch may not operate normally. If the brake switch is removed from the brake pedal, replace the brake switch with a new one.

Remove the column cover. (See COLUMN COVER REMOVAL/INSTALLATION .)
Disconnect the brake switch connector.
Verify that the continuity is as indicated in the table.
