When direct injection is started and then stopped using the active test, current ECU logic does not turn off the direct injectors and can cause DTCs P017200, P017500 and P0160300. To avoid this condition, technicians should raise engine RPM when changing back and forth between the Direct Injection and Port Injection active tests. Use the recommended procedure below to avoid this concern while testing injection mode of FKS equipped vehicles. NOTE: If the active test is used multiple times without using this procedure to raise engine RPM, it may be necessary to reset learning values for fuel trim and Air to Fuel ratio before returning vehicle to customer.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10153281-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2019/MC-10153281-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10153281","components":[{"id":"engine","name":"Engine","parent":null}],"codes":["P0172","P0175"],"topics":[],"vehicles":[{"make":"LEXUS","model":"ES350","year_from":2020,"year_to":2020,"match":null,"vehicle_ids":[]},{"make":"LEXUS","model":"GS 200T","year_from":2016,"year_to":2017,"match":null,"vehicle_ids":[]},{"make":"LEXUS","model":"GS 350","year_from":2017,"year_to":2020,"match":null,"vehicle_ids":[]},{"make":"LEXUS","model":"GS300","year_from":2020,"year_to":2020,"match":null,"vehicle_ids":[]},{"make":"LEXUS","model":"IS 250","year_from":2016,"year_to":2017,"match":null,"vehicle_ids":[]},{"make":"LEXUS","model":"IS 300","year_from":2018,"year_to":2020,"match":null,"vehicle_ids":[]},{"make":"LEXUS","model":"LS500","year_from":2018,"year_to":2020,"match":null,"vehicle_ids":[]},{"make":"LEXUS","model":"RC 200T","year_from":2016,"year_to":2017,"match":null,"vehicle_ids":[]},{"make":"LEXUS","model":"RC 300","year_from":2018,"year_to":2020,"match":null,"vehicle_ids":[]},{"make":"LEXUS","model":"RC 350","year_from":2016,"year_to":2019,"match":null,"vehicle_ids":[]},{"make":"LEXUS","model":"RX350","year_from":2020,"year_to":2020,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
