NOTE: To confirm the cold start catalyst heating, use WiTech Freeze Frame data, and confirm "Time Since Engine Start" less than 30 seconds and "Engine Coolant Temperature °F" less than 122°F (50°C) when Misfire Code was set. See Step 3 for more details. ● U0104-00 - Lost Communication With Cruise Control Module - in ACTIVE or STORED status. This software flash will allow these permanent fault codes to naturally clear. ● U0405-00 - Invalid Data Received From Cruise Control Module - in ACTIVE or STORED status. This software flash will allow these permanent fault codes to naturally clear.** Customers may experience the following: ● A potential to stall when coming to a stop with an immediate restart.
