• Current when the error occurred
• Distance in km when the error occurred
The correspondence between error codes and descriptions is given in the table below:
Error Code Description
1
OVERHEATING: this condition occurs when the temperature detected by the
sensor on the circuit board exceeds 90°C.
2
OVERCURRENT: this condition occurs when the Brake board detects an
excessive amount of current being sent to the winding.
8
OVERVOLTAGE: this condition occurs when the +12 Vdc voltage goes above
13.7 Vdc (only on the 500, 700, and 700WTV models).
16
SOLENOID OVERHEATING: this condition occurs when the NTC, connected
in series with the solenoid, detects a temperature higher than 140°C and opens the
circuit.
