НИКТО НЕ МОГ ПОДКЛЮЧИТЬСЯ! Toyota bZ 2026 Один день автоэлектрика

What’s being reviewed/checked

The video isn’t a single product review. It’s an auto-electrician’s troubleshooting walkthrough across multiple cars, including:

• Toyota bZ / bZ (2026)
• Toyota RAV4 (2020)
• Honda Civic (2026)
• A Honda-badged vehicle that turns out to be GM/Chevy-related (“Prolock 2025” mentioned)
• A Chevy Silverado-like truck, with issues involving battery cooling fans

The “product” repeatedly involved is the diagnostic/programming capability—specifically:

• A scanner
• Dealer/brand software
• The ability to connect/identify vehicles correctly (including use of special dealer functions)

---

Key points about the diagnostic/programming solution (scanner + dealer software)

Main feature / capability discussed

• Correct vehicle identification (VIN/model matching) is required for successful diagnostics.
• Some tasks require dealer program access, especially when the scanner cannot perform “special functions.”
• Certain procedures don’t work without brand-specific tools (explicitly: “dealer program is needed here”).

What worked / user experience

• With the Toyota bZ case, the technician could only proceed after:
  • forcing/trying different connection approaches, and
  • eventually using a dealer program for protected procedures.
• When VIN/model identification failed or was misread, diagnostics were unreliable until correct identification was achieved.
• On the Civic, firmware flashing/calibration succeeded using paid access and the dealer tool.

Pros

When the correct software/tooling is used, the technician can:

• Remove specific errors successfully
• Complete dealer-only procedures
• Flash firmware and calibrate systems (e.g., steering on the Civic)
• Resolve hardware connectivity issues (e.g., radar/sensors via wire repair)

Cons / limitations

• Scanner misidentification occurred:
  • Toyota bZ was incorrectly identified as Toyota 86, blocking proper diagnostics.
• Some diagnostics features are not supported:
  • “special function is not supported” until dealer software is used.
• No alternative scanner was available to compare results (“pity I don’t have any other scanner”).
• Diagnostic sessions can fail if the system can’t read/parse VIN correctly.
• Dealer functions required paid access (example given: $60 for one day on Honda).

Unique issues/problems highlighted (and what they imply about the tools)

1. Toyota bZ (2026) — post-accident / repair issues

• Dashboard showed “New Year tree” (many lights)
• Mileage: 392 miles
• Client couldn’t even connect because:
  • warranty was gone, and
  • proper identification/diagnosis couldn’t be achieved
• Scanner initially misread the car as Toyota 86 (wrong model)
• After using the dealer program, procedures were completed and:
  • dashboard lights cleared
• Wheel-sensor issue:
  • initially appeared, then was cleared, later noted as related to the sensor

2. Toyota RAV4 (2020) — back door won’t close

• Back door opens but doesn’t close
• Sensor/connector wiring issue:
  • technician couldn’t find expected sensor wires
  • implies missing/damaged wiring or connector repair
• Mentioned need to “enter a name,” suggesting a software/interface requirement

3. Honda Civic (2026) — steering replacement + security registration

• Steering wheel replaced (second-hand)
• Needed dealer program to register security case
• Paid access: $60
• Flashing firmware succeeded
• Steering calibration (position sensor) completed successfully
• Key programming note:
  • Honda key flashing is claimed to be ~4x faster than Toyota
• After a test drive:
  • everything was “great” and errors cleared

4. “Honda” (badge) but actually GM/Chevy — inspection failure (“Prolock 2025”)

• Fails inspection because not all parameters are counted correctly
• Additional non-standard device connected to the diagnostic area (“offended connector”)
• Technician removed the device (Samsara mentioned) and restored/secured the setup
• Result:
  • only one monitor not ready at the end
  • but the car still could pass inspection

5. Truck (GM/Chevy-like) — multiple sensor/system failures

• Primary issue: front-left wheel speed sensor (within another technician’s context—son disassembled battery)
• Battery cooling fans:
  • fans were transferred after a Ford Escape hybrid arrived with a fan problem
• Key detail:
  • replacing/trying fans made things worse:
    • fans “don’t start at all”
    • errors increased to two mistakes
• Diagnostic expectation:
  • when errors are read, fans should activate; they didn’t
• Additional ongoing issues:
  • footrests malfunction (sometimes open, sometimes don’t)
  • rear brake pad wear sensor issue
  • mirror failure (no image)
• Resolution attempts:
  • ongoing across days (“another working day flew by”)

---

Comparisons explicitly mentioned

• Honda vs Toyota key flashing speed
  • Honda keys are flashed about 4 times faster than Toyota.
• Implicit comparison:
  • generic scanner alone vs dealer program
  • dealer program was required for special functions and security registrations.

---

Pros/cons as concluded from the workflow (tooling/approach)

Pros

• Dealer software can unlock functions and security procedures that generic scanners cannot.
• Proper wiring checks and correct connector pinout fixes can resolve sensor/radar communication failures.

Cons

• Scanner misidentification (wrong model detected) can derail diagnostics completely.
• Some diagnostic “special functions” require dealer software.
• Replacing hardware components (e.g., fans) without proper matching can worsen the problem.
• Work can be time-consuming, sometimes requiring waiting (e.g., fan part not available until tomorrow).

Concise verdict / recommendation

For effective automotive diagnostics and programming—especially after accidents, steering security registration, and dealer-only functions—the video suggests you need:

• the correct brand dealer software/tool access, not just a general scanner.

Generic scanning may fail due to:

• VIN/model misidentification, and
• special functions being inaccessible without dealer tooling.

---

Speakers / perspectives

• Single main technician/narrator

  • Describes all troubleshooting steps
  • Notes scanner limitations and misidentification
  • Explains dealer program requirements
  • Reports calibration/flash results
  • Documents wiring repair outcomes

• Client / others (minor mentions)

  • Client request about a “retina module” being handled incorrectly (risk mentioned: airbag/RBI explosion concern; wires hanging)
  • Client/worker instructions: “change both at once” for battery fans (technician questions this approach; results were poor)
