• A recall is optional for the manufacturer

• Both are optional for technicians

Which of the following is a safety risk if a technician ignores a recall procedure?

• Ground circuit

Which cable color and markings indicate high-voltage components on an xEV?

• Red cables

Manufacturers issue TSBs instead of recalling every problem because:

• TSBs address less serious or widespread issues that do not require a full recall.

• TSBs are required by law for every vehicle issue.

• Recalls are less expensive than TSBs for manufacturers.

• TSBs are only for cosmetic problems, not mechanical ones.

Select two safety precautions you must take before working on high-voltage xEV systems.

• Disconnect the high-voltage battery and wear appropriate personal protective equipment (PPE)

• Leave the system powered on and avoid using PPE

• Work alone without informing anyone and use metal tools

• Ignore manufacturer guidelines and use any available equipment

Calibration is important after replacing an ADAS sensor or completing a wheel alignment because:

• it increases tire pressure automatically

• it changes the color of the dashboard lights

• it improves fuel efficiency directly
