2. Select “QUICK CHARGE PERMIT” in “ACTIVE TEST” mode of “CHARGER/PD MODULE” using CON-

SULT.

3. Select “QUICK CHARGE PERMIT” of “DATA MONITOR” item.

4. Switch the quick charge permit signal circuit between ON and OFF to check that the “QUICK CHARGE

PERMIT” indication changes.

5. Switch the quick charge permit signal circuit between ON and OFF to check that the “QUICK CHARGE

PERMIT” indication changes, also change the voltage between quick charge port harness connector and

ground.
