ADC Error

An ADC Error is a fatal hardware failure occurring within LWTS devices. It indicates that the Analog to Digital Converter chip—responsible for translating battery voltage into a readable value—has burned out or a physical connection between the internal boards has failed.

Key Technical Details

• The Cause: Most commonly, the ADC chip on the VB, AB, or MB board has failed. Occasionally, one of the three internal board connectors may have come loose.

• The Symptom: The device cannot read the battery voltage (vBatt). In the Device Info page, "ADC Error" will be displayed next to the vBatt entry.

• The Impact: Because the device cannot verify the battery level, it will block all flashing attempts to prevent further damage.

LWTS or 5015 is disontinuned meaning we do not support it, and it needs to be upgraded to a LWTS+ 5015P. This new device has been upgraded to help mitigate the causes of this issue mentioned, as well as others.

Resolution and Support Policy

Unfortunately, this error cannot be resolved through software troubleshooting or recalibration.

• Repair Status: Because replacement boards for the original LWTS are no longer in production, individual board replacement is no longer an option.

• The Solution: Customers experiencing this error must upgrade to an LWTS+ device.

• Associated Costs: Please note that an upgrade fee applies when transitioning from a defective LWTS to an LWTS+.

This can show up on other devices such as the X4 and BDX but in those instances it can be resolved by reloading the FW.
