Borderline visible. AI bots can crawl Car Code Finder, but the structured-data signals are thin - you are at real risk of being skipped when buyers ask ChatGPT, Claude, or Perplexity for a recommendation.

About Car Code Finder
from our crawl and measurement
Car Code Finder describes itself simply: "Big rig and semi truck fault code lookup: Cummins ISX / X15, Detroit DD13 / DD15 / DD16, PACCAR MX-11 / MX-13, CAT C15, Volvo D13, and Mack MP8." To AI engines like ChatGPT and Perplexity, though, it is barely visible: it scores 4.3 out of 10.
Our crawl found structured data on the page (BreadcrumbList) and a readable heading structure. It is missing an llms.txt file and a sitemap.
AI crawlers have visited once in our tracking, including ClaudeBot (Anthropic).

What this score means
Your AEO score measures whether AI search engines - ChatGPT, Claude, Perplexity, Gemini - can actually read your site and cite it in answers. Roughly two-thirds of sites are invisible to them. At 4.3/10, Car Code Finder is crawlable but under-signaled - fixable, and the signals above are where to start.
Frequently Asked Questions
What is a Heavy-Duty Diagnostic Code?
Heavy-duty trucks communicate over the J1939 CAN bus, a protocol defined by SAE for commercial vehicles. Unlike light-duty OBD-II (which uses P/B/C/U codes), J1939 faults are reported as SPN (Suspect Parameter Number) paired with an FMI (Failure Mode Identifier). For example, SPN 3251 FMI 0 describes a DPF outlet pressure above normal operating range.
