Service bulletin TSB1854005

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

This is a Technical Service Bulletin sent to dealers, instructing them to reprogram affected vehicles' sub-BMU with updated software. Due to inappropriate programming, the sub-BMU may falsely judge the leak detection circuit as faulty by picking up electrical noises from operation of the drive selector, brake application, or air conditioner operation. This may cause several malfunction indicators to illuminate, including: Engine Malfunction, EV System Service Required, and RBS (Regenerative Brake System), with Diagnostic Trouble Codes (DTCs) P0AA7 and P0AA8 (Leak Sensor Detection Circuit). This condition is accompanied by a decrease in vehicle power and vehicle speed being restricted to maximum of 37mph (60 km/h).
