P1A28: Understanding The Hybrid/Ev Motor System Interlock Circuit Failure
The P1A28 code is related to the hybrid battery voltage.
It indicates that the voltage of the first battery in the Energy Storage Box is too high. The Energy Storage Control Module (ESCM) uses battery voltage sensors to monitor the voltage of the batteries in the Energy Storage Box (ESB).
The ESCM monitors the voltage drop across the battery voltage sensors and uses the inputs for hybrid calculations.
