Figure 4-4 4.2.2 Scan Scan detects the systems supported by the vehicle and retrieves DTCs for all of these systems, providing a complete health check of your vehicle. Performing Scan before and after repair could help in troubleshooting and validating repairs. Pre and post scan reports can allow you to record the condition of the vehicle before and after repair for comparison. To perform a Scan, tap the Scan button. The CarPal will start scanning all the systems supported by the vehicle, and DTC retrieval will be automatically proceeded. Results are displayed progressively as the systems are scanned. Tap the system with DTCs to view the detail information of the DTCs. 16
