TECHNICAL SERVICE BULLETIN: VOLUNTARY SERVICE CAMPAIGN: 4WD ECU INSPECTION/REPLACEMENT (SC297) - This bulletin provides information to inspect and, if necessary, replace/repair the 4WD Electronic Control Unit (ECU) and wire harness and also to install a protective cover over the 4WD ECU on certain 2021-2023MY Seltos (SP2) All-Wheel Drive (AWD) vehicles produced from November 20, 2019 through March 2, 2023 that were originally sold or are currently registered in one of 36 states and the District of Columbia with significant snowfall (AK, CO, CT, DC, DE, IA, ID, IL, IN, KS, KY, MA, MD, ME, MI, MN, MO, MT, ND, NE, NH, NJ, NM, NV, NY, OR, OH, PA, RI, SD, UT, VA, VT, WA, WI, WV, and WY). In the 36 states and District of Columbia with significant snowfall, snow may be tracked into the drivers footwell area. Meltwater from this snow may enter the 4WD ECU located under the drivers seat and, over time, damage the 4WD ECU circuit board components. This can lead to the illumination of the 4WD Warning Light and deactivation of the vehicles 4WD feature. If this occurs, the vehicle can continue to be driven in the front-wheel drive mode. This service campaign is to improve protection of the 4WD ECU against water intrusion.
