BLINKING

Excessively low voltage, DTC displayed: 1 – UVP1, 2 – UVP2, 3 – UVP3

Read what to do in the next section or connect Blu-Link to GCS and check the Diagnostics tab

...

Diagnostic Trouble Codes (DTC) indicate basic malfunctions and problems with your battery, AEG, ETU or Blu-Link. You are notified about them by a LED blinking for 120 s after the problem occurs. The Blu-Link DTCs can later be read and cleared in the Diagnostics tab in GCS.

In the Event of Trouble

  1. The LED color reflects the problem type:

    • Yellow indicates a warning

    • Red indicates a problem

  2. The number of blinks determines what exactly the problem is.

DTC Explanation

...

Tip

Note
If you are using an ETU connected to Blu-Link, also check the ETU DTCs. Blu-Link is designed to withstand higher power load and lower voltage than an ETU, so in most cases, ETU protection is activated earlier and Blu-Link does not detect the problem.
