Re-Creating The Fault
Re-creating the fault is the first step in isolating the cause of the intermittent symptom. A thorough investigation should start with the customer information worksheet located in the Introduction. If freeze frame data is available, it may help in re-creating the conditions at the time of a MIL DTC. Listed below are some of the conditions for re-creating the fault:
