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 F1 (Code History)
Mode displays DTCs and description. EBCM keeps track of ignition cycles since DTC occurred. Ignition cycle information is useful in determining reason vehicle is in for service. If display indicates zero ignition cycles since DTC was set, fault is currently present. Vehicle speed information can be used to duplicate fault if an intermittent fault condition caused DTC to set. History information on up to 3 DTCs can be stored.
