Recreating The Fault
Recreating the fault is the first step in isolating the cause of the intermittent symptom. A thorough investigation should start with the customer information. If freeze frame data is available, it may help in recreating the conditions at the time of a malfunction indicator lamp diagnostic trouble code (MIL DTC). Listed below are some of the conditions for recreating the fault:
