The numbers below refer to the step numbers in the diagnostic procedures.
- 1 - The Diagnostic System Check - Engine Controls prompts the technician to complete some basic checks and store the Freeze Frame data on the scan tool if applicable. This creates an electronic copy of the data taken when the fault occurred. The information is then stored in the scan tool for later reference.
- 2 - This step determines if the fault is present.
- 3 - This step checks for voltage at the PCM when the ignition is off. The PCM should indicate battery voltage on this terminal under all operating conditions.
