A brake pedal that slowly goes to the floor when the brakes are applied, with the engine off, with no fluid loss could indicate the
master cylinder is defective
brake pads or brake shoes may be worn out
power brake booster is defective
brake fluid is low

When using manufacturer's diagnostic routines for traction control,
the technician can retrieve DTCs by using scan tools
DTCs can be ignored if they do not match customer's symptom
DTCs symptom charts are only a suggested diagnostic route
visual inspection may be eliminated if DTCs are present
When following a manufacturer's diagnostic routine, which of the following is correct?
DTC is the last step in diagnosis process
Diagnosis by symptom charts is helpful if no traction control DTC is present.
Basic brakes and engine concerns do not affect traction control performance
Traction control only works in cold weather states
When using manufacturer's diagnostic material, it is TRUE that
a general description of the system is USUALLY found in the beginning of the diagnostic section
failure to follow flow charts will usually result in repairing vehicles
known good components means that
defective parts may be substituted for diagnostic purposes
no DTCs means the system is okay
What component is the heart of the anti-lock brake system (ABS)?
electronic controller
reservoir
booster
solenoid body
An ABS system will
decrease braking force on selected wheels
increase the braking distance on high-traction surfaces
always reduce braking distance on bitumen-surface roads
decrease braking distances on gravel and snow

Technician A
Technician B
both technician
neither technician
