Bulletin Summary
Service Update - Certain vehicles may have a condition in which a false diagnostic trouble code (DTC), U3636 symptom 09, is triggered. This false DTC is resulting in customers experiencing a Malfunction Indicator Lamp (MIL) illuminated in the Driver Information Center (DIC), a Reduced Propulsion message, and a charging limited to 30% State of Charge. Since this is a false DTC, it can lead to unnecessary battery pack replacements. Dealers are to reprogram the Hybrid Powertrain Control Module 2.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
