Discuss the causes and fixes for C1425 Toyota OBDII Code

Had this same problem on 2022 Toyota's Avalon. Toyota shop finally resolved after 4 trips to shop as inherent problem. Use of led’s for brake lights does not allow for electrical path to ground. Therefore when brake pedal not being depressed signal to ecu would occasionally rise to 1.5 volts triggering ecu causing multiple warning lights including stop engine to appear. Ungrounded Wire from brake lights to ecu would induce stray voltage.
