    I vote for the KISS troubleshooting method.

    A. What is the 12v reading (1) at the jump point in the fuse box?

    B. What is the 12v reading (3) downstream of the 125a fusible link (2)?

    How about a human initiated description of what lead up to the problem in complete sentences followed by what you have tried so far.

    Jump start?

    Is there a question you need answered? Can you explain in layman's terms what you're concerned with, doing?

    Complete sentence? Where I come from the school to prison pipeline is big business/

    # Copilot : Certainly! Here’s a professional rewrite of the issues and actions taken, formatted with bullet points:

    Initial Issue and Diagnostic Actions:

    • Encountered a problem with the skid indicator, which activated the Internal Combustion Engine (ICE) drove for months taking off the battery cable to reset
    • Toyota performed a J0V update; the system functioned correctly for approximately one week.
    • Attempted to have Toyota honor a recall for an inverter converter replacement without success.
    Subsequent Issues and Troubleshooting Steps:

    • The vehicle failed to start; replaced the inverter converter with a pre-owned unit, which temporarily resolved the issue.
    • Experienced repeated power cut-offs; depleted and replaced the 12V battery multiple times.
    • Purchased a Noco charger and booster due to persistent battery drain.*
    • Noted adverse effects of humidity on the system; inspected the hybrid battery and found corroded connections.
    • Replaced the wiring harness due to poor connections
    Further Diagnostic and Repair Attempts:

    • Transitioned from cranking without starting to a lack of ‘ready’ mode indicator light./ not driven or started for 6 months
    • Performed ECU resets using paper clips on Pins 4 and 13, as well as jumper cable resets.
    • Accidentally crossed wires, resulting in blown fuses, which were subsequently replaced.
    • Utilized an Etekcity Measure Up multimeter to test fuses, relays, and power supply to the ECU.
    • Inspected wire harnesses and device connections with the vehicle powered off; discovered possible issues at the Power Control Module (PCM) with two of the four connectors showing no response.
    • Observed that the brake lights were not functioning.
    Component Replacement and Observations:

    • Attempted replacement of the PCM and Smart Key box, which did not yield positive results; reverted to the original components.
    • Noticed the orange accessory light blinking before shutdown.
    • After reconnecting the Tire Pressure Monitoring System (TPMS), the parking light remained continuously illuminated.
    Blown Fuses Identified:

    • (4/23/24 30 amp fuse under the hood.
    • Audio System (Navigation Receiver Type)
    • Navigation System (Navigation Receiver Type)
    • Parking Assist (Rear View Monitor) (Navigation Receiver Type)
    • 4/23/24 4/24/24 410 amp ECU-IG No.2 fuse.

    I’m thinking maybe the brake booster is bad , would it prevent it from going into Ready mode ?

    Hopefully you are out of shotgun shells.

    I would measure the voltages I suggested in post 3. Most likely you did not replace the 125amp fuse which is buried in the engine fuse box.
