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.
