Vehicle Check In A Boost-Action State
- Install the fuse of electric brake booster.
- Turn the ignition switch to ON.
- Depress the brake pedal several times by applying the same pedal force and check for a change in pedal height.
- Comparing to the lack-of-boost-action state, if no change occurs in the pedal height when depressed, the electric brake booster is faulty.
- If the electric brake booster still does not operate properly, perform the following diagnostic procedures. Ref. to ELECTRIC BRAKE BOOSTER (DIAGNOSTICS)>BASIC DIAGNOSTIC PROCEDURE .
