Question
How do technicians use bi-directional controls?
Answer
They command components to test system response in real time.
Explain
Bi-directional tests activate solenoids, valves, fans, pumps, and actuators to confirm module control. CHEPQ diagnostic tools allow targeted commands so technicians can verify component integrity, wiring continuity, and module logic. This is essential for troubleshooting complex systems like emissions, HVAC, and fuel delivery.
