Hybrid Batt. Current is greater than +225 A.

瀚慖f less than the specified range, test the signal circuit for a short to voltage or an open/high resistance. If the circuit tests normal, replace

the drive motor generator battery control module.

7. If all circuits test normal, replace the current sensor.
