Yamaha R15 2022 Service Manual page 24

TIP
• Some types of malfunctions are not recorded in the memory of the ABS ECU (e.g., a blown ABS con-
trol unit fuse).
• The ABS performs a self-diagnosis test for a few seconds each time the vehicle first starts off after the
main switch was turned on. During this test, a "clicking" noise can be heard from under the seat, and
if the brake lever or brake pedal is even slightly operated, a vibration can be felt at the lever and pedal,
but these do not indicate a malfunction.
