Work Instructions

Subject: Freightliner Cascadia Steering Wheel Airbags

Models Affected: Specific Freightliner Cascadia vehicles manufactured August 3, 2017, through January 30, 2019.

NOTE: Shipping instructions and freight cost reimbursement procedures for airbags removed during the Interim Recall are currently being validated and will be included in a revised FL806 bulletin in the very near future. Please continue to safely store the airbags following the EPA guideline for Class 9 Hazardous Materials.

 

Ground Inspection and Airbag Procedure

  1. Check the Coverage Info screen in OWL for an FL806 FINAL repair claim indicating this work has been done. If a claim is present, no work is needed. If there is no claim, proceed with the next step. NOTE: An FL806 completion sticker may not be a good indication that the Final repair has been completed as some dealers may have installed a sticker during the Interim repair.

IMPORTANT: Some vehicles had the airbag removed on a previous repair and will require the installation of a new airbag along with additional repair procedures which are included in these work instructions. Vehicles with an airbag currently installed will reuse the existing airbag and will be directed not to perform all of the steps in this procedure.

The airbag, if installed, is located on the steering wheel and will be clearly marked “AIR BAG.”

  1. Position the front tires straight ahead. If possible, drive the vehicle in a straight line for a short distance, stopping at the spot where service work will be done.
  2. Apply the parking brakes and shut down the engine. Chock the tires.
  3. Disconnect the batteries.
  4. Remove the dash lower center consoles, the footwell panel, the steering column lower cover, the dash switch panel, the dash auxiliary (B panel) fascia, the right-hand lower dash panel, the electronics bay cover, and the panel gauge auxiliary cover panel. Refer to Section 60.06, Subject 100 in the New Cascadia Workshop Manual for instructions.
  5. Open the hood.
  6. Inspect the vehicle frame rail GNDE and GNDP studs. See 1 and Fig. 2. Use lacquer thinner, as needed, to clean off any excess paint on electrical connections throughout these instructions.
  1. Verify that the Electrical Ground (GNDE) and the Power Ground (GNDP) frame rail studs are clean and torqued correctly. Disassemble and inspect the studs for overspray on the flat surfaces, and in between the ring eyes. Torque these frame rail ground studs 14 lbf·ft (19 N·m). Repaint the connection as necessary. See Fig. 9 on page 10.

IMPORTANT: Vehicles will have a GNDE cable either going directly to the battery negative (back-of-cab battery box equipped units) or to the left frame rail stud near the HDEP MCM (undercab battery box equipped units), but not both. Service as required for the vehicle’s configuration. The GNDP frame rail stud is located on the inside of left frame rail, just aft of the left rear engine mount.

  1. Relocate GNDP cab skin ground ( 7 on page 9) to the longitudinal bolt near the floor stud. This will require replacing the original GNDP ring eye terminal (23-12446-063) with a 6 AWG 3/8-inch ring eye cable end (p/n 23-11194-506) that fits on the 10-mm longitudinal bolt; the left cab splash shield will need removed for this repair. Remove the longitudinal bolt, and clean the cab skin around longitudinal bolt as needed. Install the GNDP ground cable and longitudinal bolt, and torque to 33 lbf·ft (45 N·m). See Fig. 3.
  2. If the GNDP floor stud is damaged or spinning in its mount when removing the nut used to mount the sleeper A/C line support Z bracket, the stud will need replaced with a bolt. Continue with the following substeps for this procedure.

NOTE: Vehicles without a sleeper A/C support bracket (typically daycabs) do not need the following repair. Continue with step 11.

10.1 Remove the driver’s-side sill cover, the lower A-pillar cover, and the lower steering wheel cover. See Fig. 4.

10.2 Roll back the driver’s-side floor mat far enough to access the center floor area above the stud, where the bolt is installed.

10.3 Locate the mounded area on the floor, directly above the GNDP stud location.

10.4 Locate and mark a spot directly between the mound and the closest rivet. The center will be approximately 5/16 inch (7.9 mm) from the edge of the rivet. Verify the area below the floor is clear, and drill a 5/16 inch (7.9 mm) hole through the aluminum floor at the spot marked. See Fig. 5

10.5    Use a cutoff wheel or suitable tool to cut the damaged stud off flush with lower floor skin.

10.6   Using a 5/16 x 1.25 bolt, install the A/C line support Z bracket, and secure it with a washer and nut. Torque to 14 lbf·ft (18 N·m).

10.7   Position the driver’s-side floor mat in the vehicle and install the-driver’s side lower steering cover, the lower A-pillar cover, and the sill cover.

  1. Inspect the GNDE pass-through stud on the engine side of the frontwall. See Fig. 6 and Fig. 8. Verify that the GNDE pass-through stud on the engine side frontwall is clean and torqued correctly. Disassemble and inspect the stud for overspray on the flat surfaces. Torque the stud 7 lbf·ft (9.5 N·m). Repaint the connection as necessary.
  2. Inspect the GNDP non-isolated stud, located on the lower aft portion of the MGJB bracket. See Fig. 6, ref. 2.

NOTE: There should always be FOUR ring eyes attached to the GNDP non-isolated stud. The nonisolated stud itself is NOT a return path to ground through the bracket and relies on the grounding cable returning to the frame for ground; confirm the 2YU GNDP cable is connected from the stud to the frame rail GNDP stud. The GNDP cab skin cable is oversized, and larger than the return to frame cable.

Verify that the GNDP non-isolated stud is clean, configured properly, and torqued correctly. Disassemble and inspect the stud for overspray on the flat surfaces, and in between the ring eyes. Verify there are exactly four (4) circuits on ring eye terminals that attach to the GNDP non-isolated stud on every vehicle. If more or less are found on this stud, combine this inspection step with the next one for GNDE MGJB, separate and group the cables until four GNDP connections are confirmed. Fan these GNDP ring eyes properly on the non-isolated stud and then torque the stud to 14 lbf·ft (18 N·m). Repaint the connection as necessary.

  1. Inspect the GNDE ring terminals on the isolated studs on the Main Ground Junction Block (MGJB). See Fig. 6, ref. 4. Verify that the GNDE connections to the MGJB are clean, configured properly, and torqued correctly.

NOTE: No particular location or order is needed for the GNDE terminals, other than ensuring that only GNDE terminals are located on the MGJB studs.

Disassemble and inspect the studs for overspray on the flat surfaces, and in between the ring eyes, then fan the ring eyes properly and torque the studs 14 lbf·ft (18 N·m). Repaint the connection as necessary.

  1. Inspect the ASAM (advanced signal detect and actuation module) power and ground connections. Check the torque at the ASAM power and ground connections. Torque them 8.6 lbf·ft (12 N·m).
  2. Inspect the GNDE pass-through stud on the cab side of the frontwall. See Fig. 10 and Fig. 11.

NOTE: The driver’s side HVAC floor duct and the main dash harness clipping tie strap may need to be removed for improved access to the cab side GNDE pass-through.

Wiggle the cable to check for movement, and service if loose. Torque the stud 7 lbf·ft (9.5 N·m).

  1. Install the ground service harness (A66-17803-001).

16.1 Remove the VPDM outer cover, then remove the 4 mounting screws and gently lower the VPDM to the cab floor and remove the back cover from the VPDM. Refer to Section 54.08, Subject 100 in the New Cascadia Workshop Manual for instructions.

16.2. Locate and remove VPDM connector J6 by loosening the captured screw from the front of the VPDM and removing the connector from the back of the VPDM. See Fig. 12.

16.3 Locate and remove the black ground wire from VPDM connector J6, pin E10 by removing the green terminal lock from the connector and then removing the wire/terminal while at the same time releasing the lock tab using tool DDE DKI0CHA17002-2, or a similar tool. See Fig. 13 and Fig. 14.

16.4 Locate the 2-pin connector provided on service harness A66-17803-001 and separate the housing from the harness mating connector housing, then remove the grey terminal lock from the connector housing.

16.5 Install the GND wire into the 2-pin connector. The GND wire can be inserted into either pin of the 2-pin connecter because both pins are populated with circuit GND-C. Once the GND wire is inserted into the 2-pin connector, install the grey terminal lock to secure the terminal. Connect the 2-pin connector with the mating harness connector.

16.6 Install the green terminal lock into connector J6, then install the connector J6 in the VPDM and secure it with the captured screw on the front of the VPDM. Tighten captured screw to 3.7 lbf·ft (5 N·m). Verify that the connector is fully seated by making sure that the green indicator next to captured screw extends from the VPDM housing.

16.7 Locate the ground module at the right lower cab under the electronics bay. Disconnect the 8-pin connector (GND_INT_DASH_O_STP_GNDP_1A) from the ground module. See Fig. 15 .

16.8 Locate the wire terminal labeled HRN GNDP on service harness A66-17803-001. Route the HRN GNDP end of the harness along the existing dash harness from the VPDM to the ground module under the electronics bay.

16.9 Using tool DDE DKI0CHA17002-2 or a similar tool, pull the red terminal lock from the module side of the 8-pin connector so that the terminal can be inserted. See Fig. 16

16.10 Insert the wire terminal HRN GNDP into pin 6 of the 8-pin ground module connector and push the red lock back into the locked position. Connect the 8-pin connector to the ground module. See Fig. 17

16.11 Route the remainder of service harness A66-17803-001 labeled CS HRN GNDP along the existing dash harness, across the dash to the base of the steering wheel clockspring.

16.12 Unplug the clockspring 6-pin connector (STRG_DASH_O_CLOCK_SPRING_1A) from the underside of the clockspring. Remove the black ground wire GND currently in pin 4 of the clockspring connector by first releasing the terminal lock and then releasing the tab that holds the terminal using tool DDE DKI0CHA17002-2 or similar tool.

16.13 Blunt cut, shrink tube, and secure the GND wire back into the harness. Install the wire terminal labeled CS HRN GNDP from service harness A66-17803-001 into the clockspring connector at pin 4, and install the terminal lock. Secure the service harness to the existing dash harness as needed using electrical tape and tie straps. Install the front and rear VPDM covers and install the VPDM.

IMPORTANT: If the airbag was removed during the repair in FL806INT and a new airbag is being installed, the final repair will also require that the air bag ECU be re-connected, two parameter changes, and the temporary airbag sun visor stickers removed.

  1. Replace the steering wheel clockspring. Refer to Section 46.01.140 in the New Cascadia Workshop Manual for instructions.

17.1 Inspect steering wheel to verify if an airbag is installed. Airbags will be clearly marked “AIR BAG”. Either remove the fasteners that attach the airbag to the steering wheel and remove the airbag, -Or remove the steering wheel cover by pulling it up.

17.2 Disconnect the clockspring connector from the right hand (RH) switch pod. See Fig. 18.

17.9   Thread the switch and airbag connectors through the hole to the right of the steering wheel, and set the steering wheel on the steering column.

17.10 Carefully align the skip-tooth on the steering wheel with the skip-tooth on the steering column shaft end and lower the wheel onto the column. Refer to Section 46.01, Subject 100 in the New Cascadia Workshop Manual for instructions.

17.11 Apply Loctite® 242 to the steering wheel bolt, then install the bolt and tighten 52 to 66 lbf·ft (70 to 90 N·m).

17.12 If the vehicle had an airbag upon arrival, reinstall the existing airbag on steering wheel. If vehicle did not have airbag, install a new airbag (14-19562-001)on the steering wheel. Connect the steering wheel switch connector and the electrical wiring from the clockspring to the new airbag module, then position the airbag module on the steering wheel.

17.13 Install two airbag retaining screws (23-14428-000) at the bottom of the steering wheel, and tighten 44 to 53 lbf·in (500 to 600 N·cm).

IMPORTANT: If the airbag was removed during the previous INT FL806 repair and a new airbag is being installed, the final repair will also require the airbag ECU to be re-connected, two parameter changes, and the temporary airbag sun visor stickers removed.

17.14 For units that arrived with an airbag installed and are reusing the existing airbag, connect the batteries and go to step 26. For units that had the airbag previously removed and required a new airbag be installed, continue with step 18.

  1. On vehicles that had the airbag removed during Interim Recall INT FL806, the airbag ECU harness connector was disconnected, wrapped, and secured and will need the ECU pigtail harness rerouted and connected to the cab harness in order to complete this repair.
