During cold engine start, rough or partial clutch operation (manual transmission only) may cause powertrain vibration similar to a misfire and cause false MIL illumination. 2. At high engine speeds with low load condition, a CVT downshift can cause powertrain vibration similar to a misfire and cause false MIL illumination. 3. At high engine speeds, improper Misfire Monitoring (P0300) threshold values may cause false MIL illumination. New software revises improper Misfire Monitoring (P0300) threshold values to false MIL illumination.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2013/MC-10172186-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2013/MC-10172186-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10172186"},{"nhtsa_id":10170846,"type":"service_bulletin","type_name":"Service bulletin","date_added":"2020-02-11","date":"2013-01-29","document_id":"TSB-13-13-001","mfr_campaign":null,"component":"POWER TRAIN; ENGINE AND ENGINE COOLING","summary":"During cold engine start, rough or partial clutch operation may cause powertrain vibration similar to misfire conditions and cause false MIL illumination.
