Diagnostic Test

WARNING: This page is about a different variant/trim than selected.

FUEL TANK CAP CLOSING CHECK
1. Check the correct closing of the fuel tank cap.
  Closing not correct
  
  Yes
  - Go To 2
  No
  - Close the fuel tank cap properly.
EVAPORATIVE EMISSION LEAK DETECTION
1. To continue testing you will need the (special tool #8404C, Kit, EELD And Accessory).
2. Connect the red power lead of the EELD to the Battery positive terminal and the black ground lead to Battery negative terminal.
3. Connect shop air to the EELD.
  NOTE:
  Do not use smoke in the Evaporative system during leak testing. Putting smoke in the system will damage the ELCM.
4. Set the smoke/air control switch to AIR to pressurize the system.
5. Press the remote smoke/air start button.
6. 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.
7. 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.
8. Remove the tube from the ELCM. Make sure to disconnect the tube that connects between the Charcoal Canister and ELCM. Not the tube that connects to the vent filter.
9. Connect the service adapter (special tool #8404-ADP, Smoke Machine Adapters) to the ELCM tube.
10. Connect the AIR supply tip (clear hose) to the adapter.
11. 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 pressurize the system.
12. 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 ELCM. Replace the ELCM in accordance with the Service Information.
  The ball stays above the red flag indicating a leak in the system;
  - This indicates that the leak is not coming from the ELCM. There is a leak elsewhere in the system. Leak test the system to find and repair the leak using one of the following methods;
  - Hydrocarbon Sniffer: Pressurize the system with smoke 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: Pressurize the system with smoke 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 and check for a leak from the Purge Solenoid. Refer to SOLENOID, EVAPORATIVE EMISSIONS PURGE, REMOVAL AND INSTALLATION .
