Leak Detector: Testing and Inspection

EVAPORATIVE EMISSION SYSTEM LEAK TEST

CAUTION: The evaporative emission system must not be pressurized to more than 3.48 kPa (14 in/H20) or damage to the evaporative emission system may occur.

1. Connect evaporative emission (EVAP) system tester SST (134-01049) or equivalent at the evaporative emission test port.
2. Access Output Test Mode using IDS or equivalent tester. See ON - BOARD DIAGNOSTIC TESTS. Initial Inspection and Diagnostic Overview

3. Select EVAPCV PID.
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 See PINPOINT TEST 10: FUEL LINE PRESSURE/FUEL PRESSURE HOLD INSPECTION. Pinpoint Test 10: Fuel Line Pressure/Fuel Pressure Hold Inspection

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