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.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-11005199-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-11005199-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11005199","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"CHRYSLER","model":"PACIFICA","year_from":2023,"year_to":2025,"match":"exact","vehicle_ids":["2023_chrysler_pacifica","2024_chrysler_pacifica","2025_chrysler_pacifica"]},{"make":"CHRYSLER","model":"PACIFICA PLUG-IN HYBRID","year_from":2023,"year_to":2025,"match":"base","vehicle_ids":["2023_chrysler_pacifica","2024_chrysler_pacifica","2025_chrysler_pacifica"]},{"make":"CHRYSLER","model":"VOYAGER","year_from":2023,"year_to":2025,"match":"exact","vehicle_ids":["2023_chrysler_voyager","2024_chrysler_voyager","2025_chrysler_voyager"]},{"make":"JEEP","model":"GLADIATOR","year_from":2023,"year_to":2025,"match":"exact","vehicle_ids":["2023_jeep_gladiator","2024_jeep_gladiator","2025_jeep_gladiator"]},{"make":"JEEP","model":"WRANGLER","year_from":2023,"year_to":2025,"match":"exact","vehicle_ids":["2023_jeep_wrangler","2024_jeep_wrangler","2025_jeep_wrangler"]},{"make":"RAM","model":"1500","year_from":2024,"year_to":2024,"match":"exact","vehicle_ids":["2024_ram_1500"]},{"make":"RAM","model":"2500","year_from":2023,"year_to":2024,"match":"exact","vehicle_ids":["2023_ram_2500","2024_ram_2500"]},{"make":"RAM","model":"4500","year_from":2023,"year_to":2024,"match":"exact","vehicle_ids":["2023_ram_4500","2024_ram_4500"]},{"make":"RAM","model":"5500","year_from":2023,"year_to":2024,"match":"exact","vehicle_ids":["2023_ram_5500","2024_ram_5500"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
