What will this report explain? Your SmogTips™ VIR diagnosis will help you understand your vehicle's smog check results. California law requires vehicle owners receive a Vehicle Inspection Report (VIR) from the smog station where their vehicle was inspected. The VIR is an invaluble tool in diagnosing your vehicle's smog check results.

Our report will begin by explaining the abbrevations listed on your VIR. If your vehicle failed for high emissions, we will cover the possible faults which typically cause an increase in HC, CO and/or NOx emissions. If your vehicle's check engine light or service engine soon light is on and trouble codes are present, we will cover those Trouble Codes as well.

Why do I need this report? To better prepare you in communicating with your smog check technician if and when you happen to need smog check repairs.

How important is my VIR? Your VIR contains invaluable information regarding the presence and proper connection of required emission components, engine diagnostic codes and freeze frame data stored in your vehicle's Engine Control Unit (ECU), results of functional tests conducted during the smog inspection, and most importantly, an accurate account of your vehicle's exhaust emission results during the smog test.

Which Type Should I Choose?


VIRs are commonly used by smog check repair technicians in assisting the diagnosis of smog check results, whether a vehicle has failed or passed the smog check. The VIR helps technicians determine if and where to begin smog check repairs, and offers valuable information about an engine's general and specific emission problems. Smog technicians often determine where to begin a smog check diagnosis based on information from the VIR.
