For certain Western Star 4700 or 5700 vehicles, power distribution modules (PDMs) are typically ordered in the aftermarket by serial number and populated with fuses and circuit breakers. It may take up to three weeks for a serial number specific PDM to be processed, made, and shipped to a dealership. In order to reduce the down time of a vehicle, an alternative PDM may be ordered fully populated with fuses and circuit breakers and delivered the next day. A cost increase may be associated with this option.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10181086-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10181086-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10181086","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"WESTERN STAR","model":"4700","year_from":2020,"year_to":2021,"match":"exact","vehicle_ids":["2020_western-star_4700","2021_western-star_4700"]},{"make":"WESTERN STAR","model":"5700","year_from":2020,"year_to":2021,"match":"exact","vehicle_ids":["2020_western-star_5700","2021_western-star_5700"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
