DTC P0555-11: Brake Booster Pressure Sensor Circuit Short to Ground; DTC P0555-15: Brake Booster Pressure Sensor Circuit Short to Battery or Open [10/2022 - ]: Description

If the engine stop and start ECU judges that the signal received from the vacuum sensor assembly is abnormal, it stores DTC P0555-11 or P0555-15 and blinks the stop and start cancel indicator light.
