(No Codes, all Systems Clear) (No Warning Lamps on) (No visual Air Bag Deployments)
This type of scan is done to a vehicle that does not display any warning lamps, symptoms or an obvious air bag deployment. Purpose is to check if any codes are set in any system of a vehicle and what systems the vehicle is equipped with on its computer network. This scan remains a “Quick Scan” when the results are “no codes in any system” the scan type changes to an Inspection Scan if trouble in a system is found that require further inspections, diagnostics or assessments. In addition, a review of the repairs for the vehicle will include identification of any required calibrations that will be needed as part of the repair process. (OCS, steering angle, park assist, object detection calibrations etc. etc.) All Information is documented at this time
(Codes or electronic trouble is present with vehicle) (Air Bag Deployment) (Warning Lamps on)
This type of scan is applied when any warning lamps or messages are seen, visible air bag deployments, or codes found during a quick scan that did not illuminate a MIL (Malfunction Indicator Lamp, AKA Check Engine Light), this takes a bit longer and more effort and knowledge by a diagnostic technician than a quick scan being that codes, data and electronic assessments are taking place. The Technician performing this and reviewing the data must have the knowledge of vehicle systems and functions to make on car inspections, testing, or part replacement recommendations. If systems are identified that require specialized vehicle set up, targeting etc., this must be identified and planned for in the repair plan for possible subletting to complete the task if shop is not equipped.
- If an Air Bag deployment has occurred the system is evaluated to determine if all stages of multistage air bags have deployed or if live detonators are still present in deployed devices
- Air bag module is evaluated electronically to determine if replacement is needed
This Type of scan is done during repair process and application is conditional
This type of scan applies in 2 different situations.
- A known problem that requires a scan tool to access data, troubleshoot, reset systems, program a replacement module etc. to proceed with vehicle repairs, a final completion scan will need to be done to clear codes, perform calibrations and verify repairs when vehicle assembly is complete before QC (quality control) stage.
- When additional trouble is found with the vehicle that requires on-vehicle repairs or on vehicle pinpoint troubleshooting during a completion scan. The scan type will be changed to a diagnostic scan. If the shop is not equipped with trouble shooting tools (Test Lamps, Volt meters, etc.), a technician with the skill set to follow guided instructions, or shortcomings in diagnostic applications, recommendations will be made to sublet the repair to a skilled equipped shop, dealership or specialized mobile technician
This type of scan is done when vehicle is completely re-assembled before final QC. Required calibrations and/or necessary programming procedures are done, all systems check and all system code clear is done. Verification of warning lamps and basic system functions are verified with all calibration procedures and scan results documented.
If additional trouble is found, or procedures will not complete due to incomplete repairs, electrical connection issues or defective parts, the scan changes to a Diagnostic scan and returns to repair for additional correction or on car troubleshooting.
This Type of scan is conditionally based and done only after a completion scan, final QC and road test are complete. Conditions below indicate when a follow up scan is needed. Completion scan results must be available for comparative purpose.
- If a warning lamp illuminates during or after QC with road test
There are several fault types that can be present that will not set a code with or without a warning lamp until the particular function is actuated. Examples are cruise control, evaporative emissions, cooling fans, HVAC functions, park assist objet detection etc.
- If symptom(s) or function(s) is/are found to be inoperative during QC procedures.
If a symptom is found such as window, or liftgate functions inoperative, lighting functions inoperative passive entry etc. a follow up scan can show additional fault codes or returning fault codes that were cleared during a completion scan session.
- If a particular concern is seen during a completion that warrants additional conformation by double checking the system with a follow up scan for verification purposes.
During a completion scan a follow up scan may be recommended base on the nature of repairs or procedures performed during completion.
- If a customer returns with a warning lamp or symptom
Some faults can take several drive cycles, key cycles or specific conditions before they will set. Additionally, other faults can occur or systems fail coincidentally after a repair.
