System Leak Test

CAUTION: The evaporative emission system must not be pressurized to more than 3.48 kPa (14 in/H2O) or damage to the evaporative emission system may occur.

1. Connect Evaporative Emission System Leak Tester MZ254AT3641 or equivalent at the evaporative emission test port.
2. Access Output Test Mode using NGS tester.
3. Select EVAPCVPID.
4. Select ALL OFF mode and press START to close the canister vent solenoid.

NOTE: Output Test Mode will default to its normal state after 10 minutes, after the vehicle is started or after cycling the key OFF then ON.

5. Follow the tester instruction:
- If the system passed leak test, no leak exists.
- If the system failed leak test, perform TEST 11: FUEL LINE PRESSURE / FUEL PRESSURE HOLD INSPECTION, See Powertrain Management, Testing.

NOTE: The leak tester detects smaller leak than minimum requirement in the PCM. Drive cycle procedure should be final confirmation method.
