If the DTCs return, go to REPAIR PROCEDURE. • If the VIN does not qualify for service bulletin 16-034 or if the bulletin has already been completed, go to REPAIR PROCEDURE. 2018-20 models, go to SOFTWARE UPDATE, then go to REPAIR PROCEDURE. SOFTWARE UPDATE NOTE: • • • • • • • Make sure the 12-volt battery is fully charged before starting an update. Connect a fully charged jumper battery to the vehicle, and leave it connected during the entire procedure to maintain steady voltage. Do not use the GR8 because the vehicle requires a steady electrical current. Control module failure caused by the improper completion of a software update (early key cycle, low battery voltage, disconnected DLC cable, etc.) is not covered by warranty. If an error occurs during the update or the i-HDS freezes, do not disconnect the battery or turn the ignition to OFF. Reboot the i-HDS, and start over. To prevent control unit damage, do not operate anything electrical (headlights, audio system, brakes, A/C, power windows, door locks, etc.) during the update. Warranty reimbursement for technician labor is not allowed for routine checking/installation of any available software update. 1. Update the PGM-FI software using the J2534 Rewrite software with the DST-i. Refer to service bulletin 01-023, Updating Control Units/Modules. Page 4 of 16 CARBON CLEANER ASSEMBLY INSTRUCTIONS NOTE: If the carbon cleaner tool is already assembled with new media cleaner, skip to REPAIR PROCEDURE on page 9. 1. Remove all the equipment from the carbon cleaner canister to ensure that the following items are included: • • • • • • Inlet air pressure regulator Nozzle with depth stopper 5R7 intake port adaptor and spacer (can be reordered as 07AAK-5R7A130) Two black silicone universal intake port adaptors and one blue silicone hose coupler. (only the blue silicone coupler is used) Safety goggles Carbon Cleaner Filter (not shown in photo, can be reordered as 07AAK-5R7A120) 2. Install the air pressure regulator through the regulator bracket on the outside of the canister. Make sure you tighten the regulator nut to secure it. 3. Install the appropriate air fitting on the air regulator for your shop’s compressor lines. Page 5 of 16 4. Install the clear tube into the right end of the air regulator. To ensure that it is in place, tug lightly on the tube. 5. Install the filter on the rim of the canister. If it’s not on properly, the motor assembly will not close. Page 6 of 16 6. Fill the canister with new (unused) media to approximately 5 mm to 10 mm from the bottom of the suction hose receptacle. NOTE: Using any other type of media could damage the vehicle or might not repair the vehicle correctly. Use only the media listed in the table above for this repair. 7. Install the motor assembly on top of the base. Use the latches on the sides to seal it to the base of the canister. Page 7 of 16 8. Install the nozzle on the handle assembly and tighten with a 15 mm open-ended wrench. 9. Confirm that the length from the tip of the nozzle to the depth stopper measures 80 mm. If not, adjust the depth stopper so that it is. NOTE: If the depth stopper isn’t correctly adjusted, you may cause damage to the valves and valve stems. 10. Insert the suction hose to the suction hose receptacle until you hear a click. Once it is all the way in, lightly tug on it to ensure that it’s properly installed. Page 8 of 16 REPAIR PROCEDURE 1. Remove the intake manifold and insulator. See the service information. 2. Remove the fuel rail cover. NOTE: Do not remove the fuel rail. 3. Raise the vehicle on a lift and remove the right front tire. 4. Turn the crankshaft to align the No.1 position at top dead center. The white mark on the crankshaft pulley lines up with the pointer. Page 9 of 16 5. Confirm the intake valves A and B of cylinder #1 and #2 are closed. 6. Tape off the ports on cylinders #3 and #4 to prevent debris from entering the ports. Page 10 of 16 7. Install the intake port adaptor on cylinders #1 and #2. Use the spacer from the kit and the intake manifold nut to ensure the adaptor is installed correctly. Torque the nut to 24 N·m (18 lb-ft). NOTE: Make sure the tabs on the inside of the adaptor are correctly inside the intake port. If they are not, it will not be flush with the cylinder head. Page 11 of 16 8. Attach the carbon cleaner suction hose to the port adaptor using the blue silicone hose coupler shown below. NOTE: Make sure the carbon cleaner suction hose is attached to the larger end of the blue silicone hose coupler. 9. Confirm the air flow valve on the trigger is closed. Page 12 of 16 10. Connect a shop air supply hose to the air pressure regulator. 11. Make sure that the air pressure on the air valve gauge reads 80 psi before use. To adjust the pressure, pull the pressure adjustment knob upward, and turn it clockwise or counterclockwise until the pressure is correct. Once it is correct, press it down to relock. 12. Turn the suction power switch on the front face to ON. NOTE: If this switch is not ON while you are cleaning the ports, you may damage the valves. Page 13 of 16 13. Place the nozzle of the handle assembly in the opening of the intake port adapter for cylinder #1. Make sure that the depth stopper is touching the intake port adaptor. Do not apply force onto the depth stopper when inserting the nozzle into intake port, as it will result in displacement of the depth stopper. ⚠ CAUTION Damage to the surrounding area or injury to yourself may occur if the nozzle is removed from the intake port adaptor during the cleaning process. The media is applied with high pressure from the nozzle. Do not remove the nozzle during the cleaning process. 14. Once the nozzle is in place, open the air flow valve on the handle so that it is vertical. Aim the nozzle at valve A and hold the trigger to start the cleaning process. Clean valve A for 2.5 minutes. Then, aim the nozzle at valve B and repeat the process. NOTE: • • When cleaning the valves, move the nozzle in an up and down motion to ensure a proper cleaning. Do not insert the nozzle past the 80 mm depth stopper. 15. Once you are done with cleaning both valves on a cylinder, switch the air flow valve to the closed position. Keep the suction on for 5 to 10 seconds to extract any remaining media in that cylinder. Once completed with cylinder one, repeat steps 13 through 15 for cylinder two before proceeding to step 16. Page 14 of 16 16. Turn the suction power switch off, remove the adapter from cylinders #1 and #2 and confirm that the remaining media is removed. If media is still left, turn the suction power switch back on and apply the suction hose directly onto the cylinder head. NOTE: Even after extracting the media in the area, there may be small amounts of media left. This is acceptable to leave. 17. Apply a paint mark on the edge of the crankshaft pulley, 180 degrees from the pointer. Then, turn the crankshaft pulley clockwise so that the paint mark aligns with the pointer. This will set it to TDC for cylinder #3. Remove the tape and confirm the intake valves for cylinders #3 and #4 are closed. 18. Tape off the intake ports on cylinders #1 and #2 to prevent debris from entering the ports. 19. Repeat steps 7 through 16 for cylinders #3 and #4, then proceed to step 20. 20. Remove the tape. 21. Install all the removed parts in the reverse order of removal. 22. Once the repair is complete, empty the carbon cleaner tool of the used media. NOTE: • • • Do not reuse the used carbon cleaning media. Used media must be removed from the cleaning tool after each repair. (See page 15 for removal instructions.) Clear any DTCs Page 15 of 16 REMOVING THE USED CARBON CLEANER MEDIA 1. Remove the motor assembly off the base of the canister. 2. Inspect the condition of the filter for tears or clogs. Knock off any media that might be stuck on the filter by tapping it. If you notice a lack of performance from the motor assembly, replace the filter. 3. For removal of the old media, dump it out of the base of the canister. For any media in the hose, tilt the canister upside down at about 45 degrees so that media can flow out of the hose.
