Evaporative Loss System Check - Clarified Procedure

ISSUE:

A mandatory testing tool was previously issued to enable the detection and repair of leaks from the dual canister evaporative emission system which is present on vehicles within the above VIN ranges. This bulletin is supplied to supplement the user's manual issued with the kit.

ACTION:





The "Evaporative Emission Tester for OBDII, 134-00056J", manufactured by K-Line Industries Inc., can pressurize the fuel and evaporative emission system and then check for any leak from that system by use of the ultrasonic leak detector. The tester is equipped with all the tools necessary to diagnose any EVAP system fault. The inert gas, (nitrogen or argon), used to pressurize the system, must be obtained locally.

Assemble the tester according to the manufacturer's instructions supplied with the tester.

!WARNING:
Never attach the tester to a cylinder of combustible gas. Only cylinders of nitrogen or argon gas, which are in good condition and properly maintained, should be attached to the tester. At least one gas cylinder should be installed in the equipment stand, to act as ballast, to prevent it overturning.

Install the gas regulator on the gas cylinder.

!WARNING:
The gas cylinder is pressurized to 2650 psi. Ensure that the regulator is correctly attached to the cylinder and that it is tightened securely.

Note:
The primary gauge will show the current cylinder pressure, e.g. 2650 psi. The secondary gauge will show 10 to 12 psi., these limits are set at the factory and are not adjustable.
