Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Mode F3 (ABS Snapshot)
Mode helps isolate intermittent problems by capturing data before and after fault condition.
If MANUAL TRIGGER mode is selected, Tech 1 will wait for ENTER to be pressed before storing speed sensor information. All stored information can be displayed and examined for conditions which might indicate a problem.
If AUTOMATIC TRIGGER mode is selected, Tech 1 will capture data which deviates from normal conditions but may not set a DTC, such as driving over bumpy roads or railroad tracks. Condition may be caused by loose connections or intermittent wiring problems. While Tech 1 is waiting for a trigger, ENTER or F9 key may be used to force a trigger.
