XJ DIAGNOSTIC ASSISTANT

AI-GUIDED HARNESS FAULT DIAGNOSIS

ABOUT THIS TOOLSelect your XJ generation below, then describe the problem. I'll ask about specific pin readings and guide you to root cause.Circuit codes in responses (like F22) are clickable links to the relevant diagram sheet.
How this works & why you can trust it

The AI part: When you type a question, an AI assistant (Anthropic's Claude) reads it and replies in plain English, like texting a knowledgeable friend. Understanding your question and writing a clear, step-by-step answer is the "artificial intelligence" part.

What is NOT the AI: Every answer is anchored to a fixed reference we wrote and fact-checked ourselves, built from the factory service manuals: wiring specs, pin numbers, sensor readings, relay tests, and trouble codes. That reference is a static book, not "intelligent." The AI's job is to read your question, look to that trusted reference, and explain the part that applies to you.

Why trust it: answers are grounded in that factory-sourced reference rather than random internet information, it points you to specific circuit codes you can confirm in the diagrams, and it works like a careful technician by asking for real measurements and checking power and ground first.

Keep in mind: it cannot see or touch your Jeep, so it only knows what you tell it. Treat it as a well-informed second opinion, not a substitute for a meter and your own judgment. Confirm critical steps with a measurement, disconnect the battery before unplugging connectors, and remember that any AI can occasionally be wrong.
