(a) Check for DTCs and note any codes that are output.
(b) Delete the DTC.
(c) Recheck for DTCs. Try to prompt the DTC (SFI system
and engine immobiliser system) by simulating the
original activity that the DTC suggested.
(1) If the DTC does not reoccur, proceed to A.
(2) If the DTC (SFI system) reoccurs, proceed to B.
(3) If the DTC (engine immobiliser system) reoccurs,
