Question
Why is freeze-frame data valuable for diagnostics?
Answer
It captures sensor values at the moment a fault occurs.
Explain
Freeze-frame snapshots help technicians understand the exact operating conditions when a DTC was triggered. CHEPQ diagnostic scanners display RPM, fuel trim, temperature, load, and voltage parameters tied to specific faults. This allows targeted troubleshooting instead of guesswork, leading to faster resolutions and fewer repeat repairs.
