ASE A9 stresses coolant intrusion. White smoke with coolant loss indicates a blown head gasket or cracked head allowing coolant into cylinders. Turbo seals cause blue smoke. Glow plugs affect starting, not coolant loss. Over-fueling injectors cause black smoke. ASE requires cooling system pressure tests.

ASE A4 stresses steering linkage inspection. Loose tie rod ends allow steering wheel play and cause clunks over bumps. Ball joints also clunk but primarily affect suspension, not steering play. Strut mounts create noise during turning but don’t cause looseness. Low fluid causes stiff steering, not play. ASE requires performing dry-park checks to confirm tie rod end wear.

ASE A7 stresses gauge interpretation. Equalized pressures at ambient levels indicate the system is empty of refrigerant. A weak compressor would still create pressure differences. A restriction alters pressures but doesn’t equalize them. Blend doors affect cabin airflow, not refrigerant pressures. ASE requires leak detection before recharging.

ASE A2 stresses electronic controls. A failed solenoid prevents gear change as commanded. Low fluid causes slipping, not lock in gear. Worn clutches cause slipping, not stuck shifts. Throttle bodies affect fuel delivery, not shifting. ASE requires solenoid testing or replacement.

ASE A7 stresses airflow faults. If pressures are normal but airflow is weak, the restriction is on the air side—most commonly a clogged cabin air filter. A restricted orifice tube or faulty compressor would alter pressures. Overcharge also shows abnormal pressures. ASE requires technicians to check blower speed and airflow path first.
