3.1 4 System Diagnostics

The CS4 scanner provides in-depth diagnostics for four core vehicle systems: Engine, Transmission, Anti-lock Braking System (ABS), and Supplemental Restraint System (SRS).

• Engine System: Reads and clears engine fault codes, views live data, and turns off the Malfunction Indicator Lamp (MIL).
• Transmission System: Diagnoses issues within the vehicle's transmission, including reading and clearing codes.
• ABS System: Accesses and diagnoses the Anti-lock Braking System to identify brake-related issues.
• SRS System: Checks the Supplemental Restraint System (airbag system) for fault codes and ensures proper operation.

To perform a system diagnostic:

1. From the main menu, select "Diagnose".
2. The device will automatically detect the vehicle's VIN (Vehicle Identification Number). Confirm the VIN.
3. Select the system you wish to diagnose (Engine, Transmission, ABS, SRS).
4. Choose to "Read Codes" to view current and pending DTCs, or "Clear Codes" to erase them after repairs.
