4.4.3. Fault codes When a fault occurs in the HCU, it is disabled. The fault code can be read by opening the truck's main cover and reading the code from the HCU status LED. The status LED displays the code by flashing in a sequence. The number of pulses in the sequence indicates the fault. For example, a repeating sequence of five pulses and a pause indicates error 2. The possible fault codes: •
Error 2: New software version This error appears only when a new software version is being loaded into the controller.
•
Error 4: Low battery voltage This fault is triggered if the HCU detects a drop in the battery voltage. It can indicate a problem in the batteries or supply cables. Check the condition of the battery and the supply cables. The fault can be reset by switching the controller supply off and then on.
