Forensic Vehicle Diagnostics

MC Wiring & Controls — MCWC

We find what
other shops can't.

MCWC is a specialized forensic diagnostic service built for the problems that defeat normal shops. We don't swap parts and hope — we measure, verify, and document exactly what's failing inside modern vehicle networks.

01
Specialization

We solve the problems that defeat normal shops.

Modern vehicles are rolling computer networks. When something goes wrong, it's rarely "just a bad part." MCWC specializes in the weird, intermittent, and "unfixable" — the cases where guesswork has already failed.

Think of us as the people shops call when they're stuck.

D-01
CAN Bus & Network Faults
Controller Area Network analysis, bus termination testing, and communication protocol diagnostics across all vehicle networks.
D-02
Module Communication Failures
ECU, TCM, BCM, and all control module communication faults — including lost modules, corrupted data, and programming issues.
D-03
Hybrid & EV Control Issues
High-voltage system diagnostics, BMS faults, inverter issues, and EV-specific control system failures with proper safety protocols.
D-04
Intermittent Electrical Problems
The hardest cases — faults that come and go, resist duplication, and defeat conventional scan tools. We stay the course.
D-05
Evidence-Grade Documentation
Photos, measurements, data captures, and plain-language findings that owners, attorneys, and partner shops can rely on.
02
Methodology

Forensic. Documented.
Defensible.

No guessing. No upsells. No pressure. Every vehicle gets a rigorous, documented process — and a repair path you can trust.

01
Measure & Verify
We start with instruments, not assumptions. Every signal, every voltage, every network response is measured and logged against factory spec.
02
Root Cause Analysis
We trace faults to their actual source — not the first plausible component. We don't stop until we've confirmed the cause with data.
03
Document Everything
Clear findings, plain-language explanations, photos, and data captures. Every report is neutral, factual, and defensible.
04
Trusted Repair Path
You receive a documented repair recommendation you can trust — and take anywhere. We have no incentive to sell you parts.
03
Who We Serve

A private, high-trust circle.

Public operations are closed. MCWC now supports a select group of clients where trust is already established and our documentation carries weight.

Legacy Clients
Returning Owners
Existing clients who've worked with MCWC before and return when the stakes are high. We know your history; you know our standard.
Network
Family & Inner Circle
The people closest to us get access when they need it. That's part of what "one connection at a time" means in practice.
Trade
Partner Shops
Shops that rely on our documentation when their own diagnostics have stalled. We're the quiet resource behind successful repairs.
Documentation
Warranty & Decal Clients
Owners navigating warranty disputes, manufacturer recalls, or legal matters who need neutral, evidence-grade diagnostic reports.
"One connection at a time."
— The MCWC Ethos

Every wire, every client, every story matters. MCWC isn't just about fixing machines — it's about restoring clarity, dignity, and trust for people who've been burned by guesswork.
