4.2 4 System Diagnostics

The CRP123E V3.0 / CRP123I V3.0 can diagnose four core vehicle systems:

• Engine System: Read and clear Diagnostic Trouble Codes (DTCs), view live data streams, and turn off the Check Engine Light (MIL).
• Anti-lock Braking System (ABS): Access ABS system data, retrieve fault codes, and turn off the ABS warning light.
• Supplemental Restraint System (SRS/Airbag): Detect electronic parameters, check health status, and address potential issues to ensure driving safety, turning off the Airbag warning light.
• Transmission System: Diagnose transmission issues by reading codes, viewing live data, and turning off the transmission warning light.
