Table 28: List of error codes

CodeDescriptionPossible cause / Hint or Solution

E107 Main contactor not activated [K10]

Problem with main contactor tips or cabling (open circuit). Contactor control wire not connected.

Incorrect contactor output from the transistor regulator (switched off). / Inspect the main contactor tips. Check control wires to main contactor. Check contactor drive output goes {low}. [A1]

E108 Main contactor tips welded or open circuit in coil.[K10]

E110 Incorrect rotor current value. [M1, A1]

Main contactor tips welded.

Contactor drive output in controller faulty (on) / Check main contactor tips Check contactor drive output goes {high}. [A1]

Defective transistor regulator [A1].

Can be caused by excessive moisture inside regulator. / Restart the truck.

E113 Unspecified steer servo fault Control system has detected a fault condition but is unable to ascertain the exact cause. / Restart the truck.

E114 Steer servo phase error [A5, M6]

Loss of motor phase to steer servo motor. / Check internal motor cable connections in steer servo

E115 Steer servo start up error [A5] Faulty Servo

Internal logical fault

Incorrect parameter settings. / Restart the truck.

E116 Steer servo checksum error [A5]

Can occur after new software has been loaded into truck. / Restart the truck.

E117 Steer servo communication error Not used

E118 Command mode error

E119 Steer servo error during homing operation (Time out)

Not used

Home position (steering straight) not achieved within preset time.

Home reference sensor [S65] not adjusted correctly

Faulty reference sensor / Check reference sensor gap is adjusted correctly, check wiring to sensor.

E120 Error in steer servo potentiometer Not used

E121 Steer servo error -steering angle value check

E122 Steer servo -reference supply out of range

Defective steering signal potentiometer [R2] or cabling / Restart the truck. The sum of the voltages between cables 92-94 and 93-94 =5 V Recalibrate steering. See# 36 - Steer servo calibration on page 46

Defective steer servo [A5] / Check voltage between wire nos. 91-94 = 4,5 to 5,5 V.

E123 Steer servo - Hall sensor fault Intermittent contacts inside steer servo

Defective steer servo [A5] / Check internal contacts in steer servo [A5].

E124 Steer servo - overvoltage [A5]

Fully charged battery and energy regeneration during hard reversing braking. / Restart the truck.
