With CONSULT-III
1. Turn ignition switch ON.
2. Select “EVAP SYSTEM CLOSE” of “WORK SUPPORT” mode with CONSULT-III.
3. Touch “START” and apply pressure into the EVAP line until the pressure indicator reaches the middle of
the bar graph.
CAUTION:
Never use compressed air or a high pressure pump.
Do not exceed 4.12 kPa (0.042 kg/cm2 , 0.6 psi) of pressure in the system.
4. Using EVAP leak detector, locate the EVAP leak. For the leak
detector, refer to the instruction manual for more details.
Refer to EC-34, "
EVAPORATIVE EMISSION LINE DRAWING" .
OK or NG
OK >> GO TO 8.
