Engine Diagnostics FAQ
Is reading a trouble code the same as diagnosing the repair?
No. A code identifies the system that detected a problem. Testing is still needed to determine whether the cause is a sensor, circuit, mechanical fault or another condition.
Can you diagnose a vehicle that will not start?
Yes. No-start diagnosis commonly includes battery condition, charging and starting circuits, ignition, fuel delivery and relevant computer data.
Do you diagnose more than cars and trucks?
Yes. Diagnostic work may also be available for motorcycles, ATVs, side-by-sides and small engines depending on the equipment and symptoms.
