Test Description

The numbers below refer to the step numbers in the diagnostic table.

  1. 1:  The Diagnostic System Check - Vehicle 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. 2:  This step determines if a fault is present. The scan tool should indicate Cranking only when the starter circuit is energized during engine start.
  3. 4:  This step checks for the correct voltage on the crank signal circuit. The voltage is normally high only when cranking the engine.
