The cell tap harness should be immediately disconnected from the BMS if this fault code is set. Leaving the harness connected to the BMS is likely to cause damage to the BMS and may indicate that a cell is severely … Continue reading →

This fault is a serious code that effectively disables the BMS and often causes many other fault codes to occur. When diagnosing errors, this error code should be corrected first. This error code indicates that the Orion BMS has determined … Continue reading →

This error code indicates that the voltage measured by the total pack voltage sensor did not match the sum of the individual cell voltage measurements. This error is triggered when the difference in voltage between the two measurements exceeds the … Continue reading →
