1. 4-System Diagnosis (Engine, Transmission, ABS, SRS)

This tool allows for comprehensive diagnostics across four critical vehicle systems. When a warning light appears for any of these systems, the scanner can identify the root cause.

• Engine System: Retrieves fault codes (DTCs) and real-time sensor data related to engine performance, fuel supply, ignition, intake, and exhaust systems.
• Transmission System: Diagnoses issues related to engine power transmission to the wheels, including the transmission, clutch, and drive shafts. It can retrieve fault codes, check fluid levels, and inspect sensors.
• ABS System: Identifies problems within the anti-lock braking system, which prevents wheel lockup during emergency braking. Reads ABS-related fault codes and checks wheel speed and pressure sensors.
• SRS System: Reads and clears DTCs for the Supplemental Restraint System, addressing issues with airbags, seat belt pretensioners, and the SRS ECU.
