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.

want to provide clarity regarding the rear door lighting configuration for DT vehicles equipped with sales code LB2. It has come to our attention that there is some confusion regarding the number of lights on DT rear doors. 1. Background:  In model year MY22 and earlier, DT rear doors were equipped with three lights.  However, starting from MY23, DT rear doors are correctly built with only two lights. 3. Sales Code LB2:  Vehicles with sales code LB2 are designed to have two lights on the rear doors. 4. Action Required:  If a customer complains about missing rear door lights on an LB2-equipped vehicle, please do not order part number 68291943AC.  LB2-equipped vehicles are correctly built with two lights, and adding a third light is unnecessary. Thank you for your attention to this matter. If you have any further questions or need assistance, feel free to reach out to our support team.

In repair procedure the dealerships are replacing the CAN star block connector during their root cause process with returned parts showing no trouble found. Here is a list of steps the dealers can follow to determine if they have a defective CAN star block connector using a multimeter: Step 1: Visually review CAN star block for damage and ensure back cover has all locking tabs engaged. If a bent pin, cracked or damaged housing or locking tab is not engaged is observed then replacement is required. Step 2: Identify Connector #1 as the 3 Pin Connector cavity Step 3: Measure resistance between Pin#1 and Pin#2 in Connector #1. Acceptable values are 120.4 Ohms to 139.8 Ohms. If resistance is outside of this range then replacement is required. Step 4: Measure the continuity between Pin#1 in Connector #1 to Pin#1 in each of the other 2 Pin connector cavities. If continuity is not found then a replacement is required. Step 5: Measure the continuity between Pin#2 in Connector #1 to Pin#2 in each of the other 2 Pin connector cavities. If continuity is not found then a replacement is required.
