FUSES BRAKE BOOSTER Check the brake booster function as follows: 1. With the engine off, press and release the brake pedal several times. When brake pedal movement (distance of travel) remains the same from one pedal application to the next, continue on to the next step. 2. While depressing the brake pedal, start the engine. The pedal height should drop a little. 3. With the brake pedal depressed, stop the engine. Keep the pedal depressed for about 30 seconds. The pedal height should not change. 4. Run the engine for one minute without depressing the brake pedal, then turn it off. Depress the brake pedal several times. The pedal travel distance will decrease gradually with each depression as the vacuum is released from the booster. If the brakes do not operate properly, have the brakes checked by a NISSAN dealer. 3. Remove the fuse box cover by pushing the tab and lifting the cover up. 4. Remove the fuse with the fuse puller. The fuse puller is located in the center of the fuse block in the passenger compartment.
