Diagnostic Test
- CHECK FOR ANY SERVICE BULLETINS THAT APPLY
- Before proceeding with this test procedure, perform any Service Bulletins or PCM Flash updates that relate to this fault code.
Are there any Service Bulletins or PCM Flash updates available?
Yes
- Perform the applicable Service Bulletins or PCM Flash update.
- Verify the system is not leaking by performing the Engine Off (Non-Intrusive) Leak Evaluation.
No
- Go To 2
- Before proceeding with this test procedure, perform any Service Bulletins or PCM Flash updates that relate to this fault code.
- EVAP SYSTEM INSPECTION
- Turn the ignition off.
- Perform a visual inspection for:
- Proper orientation of the ESIM Switch connector (3 O'clock position)
- If the switch is not in the proper orientation, it may cause the weighted pressure and vacuum vents to intermittently not seal correctly.
Were any problems found?
Yes
- Repair as necessary.
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
No
- Go To 3
- Proper orientation of the ESIM Switch connector (3 O'clock position)
- EVAPORATIVE EMISSION LEAK DETECTION
- To continue testing you will need the (special tool #8404C, Kit, EELD And Accessory).
- Connect the red power lead of the EELD to the Battery positive terminal and the black ground lead to Battery negative terminal.
- Connect shop air to the EELD.
- Set the smoke/air control switch to AIR to pressurize the system.
- Press the remote smoke/air start button.
- Block off the end of the tester's AIR supply tip (clear hose) while pressing the remote start button.NOTE:
The indicator ball should be resting on the bottom of the air flow meter (this is calibrated to no leak present) if the EELD is calibrated correctly.
- If the indicator ball is not resting on the bottom of air flow meter, position the red flag on the air flow meter so it is aligned with ball.NOTE:
The Gas Cap adaptor can be used instead of going through the ESIM vent. First, block off the ESIM vent before pressurizing the system because the pressure introduced by the EELD tester is higher than the ESIM vent valve threshold and will cause the appearance of a false leak through the ESIM. Doing so will also allow you to determine if the ESIM is the cause of the leak.
- Connect the service adapter (special tool #8404-ADP, Smoke Machine Adapters) to the ESIM vent hose.
- Connect the AIR supply tip (clear hose) to the adapter.
- Press the remote button to activate AIR
flow.NOTE:
Depending on the vehicles fuel level, or vehicle venting configuration, it can take several minutes to fill the system.
- Compare the flow meter indicator ball reading to the red flag.NOTE:
If the indicator ball drops down to the bottom of the air flow meter, or below the red flag that would indicate that the system is sealed and not leaking.
Select the appropriate response from the list below:
The ball drops down to the bottom of the air flow meter, or below the red flag;
- This indicates that the leak is coming from the valves inside the ESIM. Replace the ESIM in accordance with the Service Information.NOTE:
If the Gas Cap adaptor was used when testing the system the Gas Cap must be checked for a leak before replacing the ESIM.
The ball stays above the red flag indicating a leak in the system;
- This indicates that the leak is not coming from the ESIM. There is a leak elsewhere in the system. Leak test the system to find and repair the leak using one of the following methods;
- Smoke test: Attach the black hose to the adaptor and switch the EELD tester to smoke. Pressurize the system with smoke from the EELD tester and look for smoke coming from around all connections and sealing points in the system. Repair or replace the leaking component.
- Hydrocarbon Sniffer: Continue pressurizing the system and check for a leak using the TIF8800X - Combustible Gas Detector or equivalent around all connections and sealing points in the system. Repair or replace the leaking component.
- Bubble test: Continue pressurizing the system and check for a leak by applying Mopar Air Leak Detector or equivalent around all connections and sealing points in the system and look for bubbles indicating a leak. Repair or replace the leaking component.
- To check the Purge Solenoid for an internal leak, remove the Manifold Hose from the Purge Solenoid, fill the system with smoke and check for smoke coming through the Purge Solenoid. If smoke is present, replace the Purge Solenoid in accordance with the Service Information.
- Perform the Intrusive Leak Evaluation again to verify repair.
- This indicates that the leak is coming from the valves inside the ESIM. Replace the ESIM in accordance with the Service Information.
