Attachment III - Technical Information

OVERVIEW

This document details the procedure for replacing the fresh air inlet hose connector with an elbow assembly for the evaporative emissions (EVAP) canister.

NOTE!
Less than 15% of the affected vehicles may arrive at the dealership with the fresh air inlet hose disconnected from the wheel well splash shield. The evaporative emissions canister assembly must be replaced on these vehicles. Call the Special Service Support Center if replacement of the EVAP canister is required. See Evaporative Emissions Canister Assembly Replacement in this document for replacement procedures.

DO NOT REPLACE the evaporative emissions canister if the vehicle arrives with the hose attached to the wheel well splash shield.

FRESH AIR INLET HOSE CONNECTOR REPLACEMENT





1. Disconnect the EVAP canister fresh air inlet hose connector from the opening in the driver-side rear wheel well splash shield. See Figure 1.





2. Measure 12.7 mm (0.5 in.) from the bulge in the fresh air inlet hose and, using an appropriate hose cutter, cut the end of the hose off and discard. Make sure no debris falls into the hose. See Figure 2.

3. Install the new fresh air inlet hose elbow assembly into the hose and position it through the splash shield opening.

4. CAUTION: A restriction of air flow in the fresh air inlet hose may result in a slow fuel fill condition. Make sure the fresh air inlet hose is not pinched after tie strap installation.





Secure the fresh air inlet hose to the fuel tank breather tube with a tie strap as indicated. See Figure 3.

5. Proceed to Authorized Modifications Label and Proof of Correction Certificate in this document.

EVAPORATIVE EMISSIONS CANISTER ASSEMBLY REPLACEMENT

NOTE!
Call the Special Service Support Center if replacement of the EVAP canister is required.

NOTE!
Perform this procedure only if the vehicle arrived at the dealership with the fresh air inlet hose disconnected from the wheel well splash shield

1. Disconnect the battery negative cable.

2. Lower and remove the spare tire.

3. Raise the vehicle on a hoist.





4. Remove the five (5) EVAP canister assembly mounting bolts. See Figure 4.





5. Position the EVAP canister so you can access and disconnect the vapor hose from the passenger side of the EVAP canister, then the vent solenoid electrical connector, the wiring harness pin-type retainer and the vapor hose from the driver side of the EVAP canister. Once all the items are disconnected, remove the EVAP canister from the vehicle. See Figure 5.

6. Connect the vapor hose, wiring harness pin-type retainer and the vent solenoid electrical connector to the driver side of the new EVAP canister. Then connect the vapor hose to the passenger side of new EVAP canister.

7. Install the five (5) canister assembly mounting bolts. Tighten the bolts to 10 Nm (89 lb-in).

8. Lower the vehicle.

9. Position and raise the spare tire.

10. Connect the battery negative cable.

11. Perform an Evaporative Emissions System Leak Test as follows:

a) CAUTION: The evaporative emission system must not be pressurized to more than 3.48 kPa (1.03 in Hg) or damage to the evaporative emission system may occur.

Connect the Evaporative Emission System Leak Tester 310-F007 (134-00056 or equivalent) to the evaporative test port.

b) NOTE: The ignition switch must be in the Key ON/Engine OFF position.

c) Using WDS, NGS or equivalent, apply 12 volts to the canister vent solenoid.

d) Pressurize the evaporative emissions system to 3.48 kPa (1.03 inHg).

e) Monitor the system for two (2) minutes. If pressure falls below 2.0 kPa (0.6 inHg), the system has failed the leak test.

f) Repair any leaks as necessary. (NOTE: Any repairs not related directly to the EVAP canister assembly replacement are not covered by this program.)

g) Repeat the Evaporative Emissions System Leak Test until the system remains above 2.0 kPa (0.6 inHg) after the last test period.

12. Proceed to Authorized Modifications Label and Proof of Correction Certificate in this document.

AUTHORIZED MODIFICATIONS LABEL AND PROOF OF CORRECTION CERTIFICATE





1. Obtain and prepare an Authorized Modifications Label. Write your P&A code, date of repair, the program type and number, and either "EVAP CANISTER FRESH AIR INLET HOSE MODIFIED" or "EVAP CANISTER FRESH AIR INLET HOSE MODIFIED AND EVAP CANISTER REPLACED" in the space provided. See Figure 6.

2. Apply the label to a clean area adjacent to the Vehicle Emissions Control Information (VECI) label, then cover it with a clear plastic decal shield.





3. Provide California and Massachusetts owners with a "Vehicle Emission Recall - Proof of Correction" certificate. See Figure 7.
