Toyota Yaris XP210 (2020-2025) Reapir and Service Manual: Lost Communication with Battery Monitor Module Missing Message (P162B87)

DESCRIPTION The ECM and battery state sensor assembly each detect reception malfunctions. A battery state sensor assembly reception malfunction detected by the battery state sensor assembly is sent to the ECM via LIN communication. If there is a malfunction in either the ECM or battery state sensor assembly, the ECM determines that there is a LIN communication malfunction and outputs a DTC...
