Test NF-1A - No Fault Code Test Menu
Check TECHNICAL SERVICE BULLETINS (TSBs) for any pertinent information. If a TSB exists, perform corrective action. If TSB does not exist or if driveability problem still exists, check suspect system and perform indicated test. See NO FAULT CODE TEST MENU table. If system causing driveability problem is not known, perform TEST NF-2A through TEST NF-7A in sequence until problem is found.
NOTE:
Components listed below that provide an input to SBEC are being checked for a condition that WILL NOT set a fault code, but cause a driveability condition.
