The integrative predictive powertrain control (IPPC) module programming should be updated to the newest software. If the ignition short-cycles on these vehicles with the previous software, there is a risk that the IPPC module will not have time to write EEPROM data in the controller. If this occurs, the IPPC will set check sum fault 520208/19 and will require programming to clear it.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10185689-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10185689-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10185689","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FREIGHTLINER","model":"CASCADIA","year_from":2020,"year_to":2021,"match":"exact","vehicle_ids":["2020_freightliner_cascadia","2021_freightliner_cascadia"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
