9. VERIFY EVAPORATIVE EMISSION LEAK WARNING: Keep lit cigarettes, sparks, flames, and other ignition sources away from the test area to prevent the ignition of explosive gases. Keep the test area well ventilated. Failure to do so may result in possible serious or fatal injury. Turn the ignition off. To continue testing, you will need Evaporative Emission Leak Detector (EELD) (special tool #8404C, Kit, EELD And Accessory). NOTE: The fuel tank should have between 20% and 80% of fuel tank capacity to properly test the Evap system. Connect the red power lead of EELD to the battery positive terminal and the black ground lead to battery negative terminal. Block the vent hose of the Evap Canister. Connect shop air to the EELD. Set the smoke/air control switch to AIR. Insert the tester's AIR supply tip (clear hose) into the 0.040 orifice on the tester's control panel. Press the remote smoke/air start button. Position the red flag on the air flow meter so it is aligned with the indicator ball. When the calibration is complete, release the remote button. The EELD flow meter is now calibrated in liters per minute. Install the service port adapter (special tool #8404-14, Adapter, Evaporative Service Port) on the vehicle's service port (if equipped) or install the service adapter (special tool #8404-ADP, Smoke Machine Adapters) into the filter line. Connect the AIR supply hose from the EELD to the service port (if equipped) or to the adapter (special tool #8404-ADP, Smoke Machine Adapters). Press the remote button to activate AIR flow. NOTE: Larger volume fuel tanks, lower fuel levels, or vehicles equipped with a Flow Management Valve may indicate high flow and will require four to five minutes to fill. Compare the flow meter indicator ball reading to the red flag. ABOVE the red flag indicates a leak present. BELOW the red flag indicates a sealed system. Is the indicator ball above the red flag? Yes Go To 10 No Go To 12
10. EVAPORATIVE EMISSION LEAK DETECTION NOTE: A thorough visual inspection of the EVAP system hoses, tubes, and connections may save time in your diagnosis. Look for any physical damage or signs of wetness at connections. The strong smell of fuel vapors may aid diagnosis also. Remove the Air supply hose from the service port or the adapter (special tool #8404-ADP, Smoke Machine Adapters). Connect the SMOKE supply tip (black hose) to the service port (if equipped) or to the adapter (special tool #8404-ADP, Smoke Machine Adapters). Set the smoke/air control switch to SMOKE. NOTE: The flow meter indicator ball will not move at this point. Press the remote smoke/air start button. NOTE: Make sure that smoke has filled the EVAP System by continuing to press the remote smoke/air start button, remove the vehicle fuel cap, and wait for the smoke to exit. Once smoke is indicated reinstall the fuel cap. NOTE: For optimal performance, introduce smoke into the system for an additional 60 seconds; continue introducing smoke at 15 second intervals, as necessary. While still holding the remote smoke/air start button, use the white light (special tool #8404-CLL, Light, White) to follow the EVAP system path, and look for the source of the leak indicated by exiting smoke. If a leak is concealed from view (i.e., top of fuel tank), release the remote smoke/air start button, and use the ultraviolet (UV) black light (special tool #8404-UVL, Light, UV) and the yellow goggles (special tool #8404-20, Goggles, Yellow) to look for residual traces of dye that are left behind by the smoke. The exiting smoke deposits a residual fluid that is either bright green or bright yellow in color when viewed with a UV light. NOTE: The EVAP system is divided into three zones. A leak from any of these zones can cause this DTC to set. The lists below specify the possible leak points in that specific zone. For further assistance see the Zone Identification Charts below. ZONE 1 EVAP SYSTEM COMPONENTS CALLOUT DESCRIPTION 1 Fuel Tank 2 Fuel Tank Vent (Check Valve) 3 Vapor Line to Canister 4 Fuel Tank to Canister Vapor Line 5 Control Valve 6 Fuel tank Pressure Sensor 7 Vapor Recirculation Line 8 Fuel Cap 9 Fuel Fill Tube 10 Fuel Fill Tube to Tank connector 11 Fuel Fill Check Valve ZONE 2 EVAP SYSTEM COMPONENTS CALLOUT DESCRIPTION 1 ESIM Switch 2 Filter 3 Evaporative Purge connection 4 Fuel Tank to Canister Vapor Line 5 Evaporative Canister 6 ESIM Switch O-Ring Seal ZONE 3 EVAP SYSTEM COMPONENTS CALLOUT DESCRIPTION 1 Connection to Canister 2 Chassis Purge Line 3 Connection to Evaporative Purge Harness 4 Chassis Evaporative Purge to Engine Vacuum line and connection 5 Evaporative Purge Valve 6 Evaporative Purge Vacuum Line 7 Connection to Chassis Line NOTE: Carefully inspect the vent side of the Evaporative Canister. Due to the filtering system in the canister the smoke or dye may or may not be visible. Introducing smoke into the filtered side of the canister may assist in locating the leak. Select the appropriate response from the list below: A leak was found at the gas cap or fuel filler tube Go To 11 A leak was found in one or more of the EVAP system zones If the leak is at a hose connection, remove the hose then reconnect the hose and check for a leak again. All other leaks repair as necessary. Perform the POWERTRAIN VERIFICATION TEST. Refer to «POWERTRAIN VERIFICATION TEST»(ref-646322-S42876527142014072800000) . No leaks were detected Go To 12

Immediately after key off.

At key off, the Powertrain Control Module (PCM) evaluates the state of the ESIM Switch for open or closed. After a period of time when the engine is off, the EVAP purge system should equalize to ambient pressure. If the ESIM switch opens the tests passes and the PCM continues a power down routine. If the switch does not open at any time during the current drive cycle, then the PCM stores the state and it is evaluated again at the next key on. If the PCM does not detect that the ESIM Switch is open, an error is detected. Two Trip Fault.
