Mechanic Diagnostic Receipt Examples

See how our generator formats diagnostic receipts: labor-only services with scan tool fees, DTC fault codes, and technician notes. No parts lines on a pure diagnostic visit.

Diagnostic receipts cover OBD-II scans for check engine lights ($80-$150) and comprehensive engine diagnostics ($150-$300) where the shop investigates symptoms before quoting a repair. These receipts document the diagnostic procedure, codes pulled (e.g., P0420 catalyst efficiency), and recommended next steps.

Frequently Asked Questions

What is on a mechanic diagnostic receipt?

A diagnostic receipt is typically a labor-only service document. It shows the diagnostic labor charge (usually 1.0 hour at the shop rate), a scan tool fee if the shop charges separately, the DTC fault codes retrieved, and technician notes describing the root cause. No parts appear unless repairs were authorized on the same visit. The receipt may note whether a follow-up repair estimate was provided.

What is an OBD-II code read receipt?

An OBD-II (On-Board Diagnostics II) code read is a short diagnostic service where the technician plugs a scan tool into the vehicle's OBD-II port under the dash to retrieve stored Diagnostic Trouble Codes (DTCs). The receipt lists the code read as a 0.5-hour labor charge, prints the DTC codes retrieved (e.g. P0420), and includes a technician note explaining the fault. It is the lowest-cost diagnostic service and often applied toward a repair if the customer authorizes the work.

Is a diagnostic fee applied toward the repair cost?

Many independent shops credit the diagnostic fee toward the repair if the customer authorizes the work on the same visit. This is usually noted on the receipt as a credit line or stated in the terms at the bottom. If the customer declines the repair, the full diagnostic fee is charged. The generator supports both credit-applied and standalone diagnostic receipt formats.

Are diagnostic receipts labor-only or do they include parts?

A pure diagnostic receipt is labor-only, it shows the diagnostic labor hours and scan tool fee but no parts. If the diagnosis leads to an immediate repair on the same visit, the receipt may combine the diagnostic labor with the repair labor and parts on a single document. Our examples show both scenarios so you can choose the format that matches your situation.
