SEMI TRUCK PRE-PURCHASE INSPECTION

Same-day inspection. ECM scan included. Full photo report. $350 flat.

A pre-purchase semi truck inspection covers the engine, transmission, brakes, suspension, tires, electrical, and cab condition. Sell My Rig inspectors use a J1939 diagnostic cable to pull ECM fault codes and aftertreatment status, check brake lining depth with calipers, measure tread depth at every position in 32nds, photograph 200+ checkpoints, and verify the VIN against the door placard and GVWR sticker. The full report is delivered digitally same day, typically within hours of the inspection.

FAQ

Questions About Semi Truck Inspections

How much does a semi truck inspection cost?

Sell My Rig Inspections charges $350 for a Standard semi truck inspection, which includes an ECM scan, brake check, tread depth measurements, and 200+ photos delivered same day. Basic starts at $199 and Premium (lender-grade with oil analysis) is $499.

How fast do I get the inspection report?

Reports are delivered the same day the inspection is completed. Sell My Rig inspectors upload photos and findings directly to the platform and you get instant digital access — no waiting 2-3 business days.

What does the ECM scan check on a semi truck?

The ECM scan connects to the J1939 diagnostic port and pulls all stored fault codes, active warnings, and aftertreatment status (DPF, DOC, SCR). It reveals hidden engine issues a visual inspection cannot catch.

Do you inspect semi trucks in my city?

Yes. Sell My Rig Inspections has inspectors in all 50 states. Enter your city or zip when you order and we dispatch the nearest qualified inspector — same day.

Who performs the semi truck inspection?

Certified mechanics with commercial vehicle experience. ECM inspectors carry a J1939 diagnostic laptop and all inspectors carry E&O coverage. They are independent — not employed by any dealer.

What if the inspection finds major issues?

Sell My Rig reports exactly what we find — no pass/fail grades. You get the data and decide whether to renegotiate, walk away, or buy with confidence. Most buyers use findings to negotiate a better price.
