Diagnostic Aids
WARNING: This page is about a different variant/trim than selected.
- When a circuit fault is detected on the high voltage interlock loop that feeds the Starter/Generator and the vehicle hood is opened, the Starter/Generator Control Module will respond by turning off inverter switching. This will prevent the Starter/Generator from charging the Hybrid/EV Battery Pack and supplying voltage to the Starter/Generator Control Module 12 V output. Operating in this manner will cause an eventual discharge of both the high voltage Hybrid/EV Battery Pack and the 12 V battery.
- Because the 5 V reference circuit also supplies voltage to the brake pedal position sensor, a circuit fault on the high voltage interlock loop that feeds the Starter/Generator will also cause hybrid functions that rely on the brake pedal position, such as auto-stop and regenerative braking, to be disabled.
