BMS-A135
BMS_a135_HW_BMB_Diagnostics_Failure
What does BMS-A135 mean?
Tesla alert code in the Battery Management System (BMS) module. BMS detected a pattern test failure on a BMB The BMS runs the BMB pattern diagnostics and detects a deviation from the expected results for any device in the chain The BMS runs the BMB pattern diagnostics and receives the expected results for all devices in the chain May indicate a potential BMB hardware failure which could manifest in more severe alerts from faulty BMB readings CAC difference of bricks within a module exceeds threshold Indicates that a brick's voltage slope is significantly less than the average. A brick has fallen below the minimum brick voltage BMS has detected that one or more BMB devices exceed the over temperature threshold

Severity Notes
BMS-A135 is an Alert in the Battery Management System system. It is generally safe to continue driving, but have it checked at your next scheduled service.
