Technician's observations can refer to spongy or stuck hydraulic lash adjusters. Exhaust lash adjusters found with a "spongy" condition (compressible plunger) leading to the assumption of being defective/malfunctioning. EXHAUST lash adjusters are designed to be COMPRESSIBLE by hand. Intake lash adjusters found with a stiff or stuck condition (non-compressible plunger) leading to the assumption of being defective/malfunctioning. INTAKE lash adjusters are designed to be NON COMPRESSIBLE by hand. Do Not Replace EXHAUST lash adjusters when the following condition is present: should be compressible, but they will exert a reactionary spring force during compression and return to full expansion without a compression force. Do Not Replace INTAKE lash adjusters when the following condition is present: should feel very firm and difficult to compress. Once the correct functioning of the intake and exhaust lash adjusters is validated with the procedure above, refer to the Service Manual "HYDRAULIC LIFTER(S) NOISE DIAGNOSIS" procedure. After the corresponding service procedures from the Service Manual involving the Lash Adjusters have been conducted, refer to the detailed instructions in the Service Manual to diagnose and/or service any other component.

Refer to SOL # S2509000004. It is also important to confirm that the vehicle being repaired has the latest calibration/software update for oil pump operation mode (high pressure mode) during engine start up. RU, VF, WL & WD vehicles already include the latest oil pump mode in all 25MY and beyond. 24MY service releases are also available. JL & JT were updated as a running change in 24MY and beyond (08/15/24 & 08/19/24 respectively). 24MY service releases available. DT was updated starting 25MY and beyond. If the vehicle to be repaired is a 24MY vehicle with a service release available, please follow the released service procedures to update to the corresponding calibration/software.

turning off, wipers not returning to position, heated steering wheel not working and/or steering controls inop, please follow these steps: 1.- Review if there is any active DTC. Refer to service library procedure and follow diagnosis steps. 2.- If failure still present, make sure all the switches', horn's, heated steering wheel, airbag's harness are properly connected and there is no corrosion or pinching, disconnect the switches & reconnect them, and reverify the issue. 3.- Verify if failure is still present, review if there is lack of communication between SCCM and BCM. For example, activate turn signals or wipers. 4.- Read at the BCM diagnosis session if BCM is receiving information from SCCM. Through diagnosis review if activation from horn, wipers or turn signal is requested and are working. 5.- Disconnect the SCCM fuse for around 30s,and repeat the previous steps to see if failure still present. 6.- Do a hard reset to BCM and evaluate if any DTC is set. Retest if failure still present. Review the active DTCs. 7.- Before replacing the SCCM disconnect it and reconnect it again. Note: Wipers position is not controlled by SCCM, verify motor wiper status if issue continues. If request from SCCM is sent to BCM, then verify if the communication to wipers is not working properly. If there are no DTC's active, physical defects, steering controls inop, wipers inop, heated steering wheel inop, then SCCM does not need to be replaced."

These conditions may be related to worn intake camshaft high lift lobe(s), and intake rocker arm(s) high lift slider. High mileage failure (10,000-60,000 miles). 1. Remove the valve cover(s) per the released service procedures. The use of a stethoscope or DTC specific cylinder misfire codes can help to locate the condition to the left or right bank. 2. Once it has been visually confirmed that there is wear on the high lift intake lobe(s) & rocker arm(s) slider, there is a special service kit for this type of repair which should be used, instead of replacing the complete engine/long block. This kit contains the parts required for the repair (intake cam, rocker arms, sealer and gaskets). Once it is confirmed that the repair will be done using the camshaft/Rocker arms kit, it is also important to confirm that the vehicle being repaired has the latest calibration/software update for oil pump operation mode (high pressure mode) during engine start up. RU, VF, WL & WD vehicles already include the latest oil pump mode in all 25MY and beyond. 24MY service releases are also available.

observe that the interior door panel is not properly seated or attached. Panel(s) may appear warped or out of position in some areas. No signs of damage should be expected. How to diagnose: Visually inspect the door panel(s) for proper installation and check for the presence of broken or loose clips. Remove the panel and inspect clips and clip towers. Next step would be reinstalling the panel if visual inspection does not find any issues. Repair Procedure: Require a picture of the door panel(s) in the 'as found' condition so we can understand what warped means in the claims that are being created. After, check the door panel for proper installation and for the presence of broken or loose clips. Remove the panel, following normal servicing procedure, and inspect clips and clip towers. If any clips are broken or missing, replace prior to reinstalling original door. After confirmation that no loose/broken/damaged clips and/or clip towers, and reinstalling door panels does not correct issue, then a 'front door trim panel' kit / claim would be acceptable. In this case, Stellantis would like to request the panel back. How to validate fix: Verify that door has no loose/broken/damaged clips and/or clip towers. Replace any broken/missing clips where possible. Then validate that reinstalling the interior door panel addresses initial issue made within the claim.

layer of condensation on the SYMPTOM: inside of the lenses Fig. 1. This may be reported after the lamps have been turned on and brought up to operating temperature, turned off and then rapidly cooled by cold water (such as rain, or the water from a vehicle wash). Lens fogging can also occur under certain atmospheric conditions after a vehicle has been parked outside overnight (i.e. a warm humid day followed by clear cool night). This will usually clear as atmospheric conditions change to allow the condensation to change back into a vapor. Turning the taillamps on will usually accelerate this process. This bulletin is to communicate the procedure for rear taillamp condensation clearing.

If the condition is replicated, then check: 1) for kinked or pinched Clean Air Hose between the ESIM and the EVAP Air Filter; 2) for plugged EVAP Air Filter; 3) for kinked or pinched Vapor Hose between the Fuel Tank and the Vapor Canister. If the EVAP Filter is restricted, the replace the Filter. -Check if the Vapor Canister is flooded with fuel or the Recirculation Line has fuel. If fuel is found in the Vapor Canister or the Recirculation Line, then drop the Fuel Tank, remove the FDM Lock Ring to check if the internal Vapor Line is properly connected to the FDM Port. If the Vapor Line is not connected, then drain the fuel from the internal Vapor Line and properly connect to the FDM. Replace the Vapor Canister and the ESIM."

swapping the old AGS for a new one, and test if the error code returns. Very often the wiring harness presents corrosion, so make sure to check it for any damage BEFORE swapping the AGS. Corrosion in the harness disrupts communication with the AGS, which sets up the DTCs for AGS performance and lights the CEL. If the AGS is inop and it will be replaced and sent back to Stellantis also send back the wiring harness with it. Make sure to fully perform the PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE as indicated in the service library.
