The codes are divided into three groups accord- ing to the effect on the truck as follows:
Information Codes 1 to 99 Warning Codes 100 to 199 Faults Codes 200 to 999 Information:
Information codes represent current interlock status rather than faults. Information codes are not stored in the controller code history.
Warning:
A warning code is generated during normal oper- ation, and does not influence the function of the truck. Warning codes are stored in the controller code history.
Fault:
A fault code will influence the function of the truck. Depending on the severity of the fault, reduced performance or shut down may result. Fault codes are stored in the controller code history.
HYDRAULIC INFORMATION CODES 1 Boot condition not satisfied
2 Boot condition not satisfied. One or more joystick(s) is/are not in the neutral position afterPOWER ON 4 The seat switch is not operated
5 Slow signal (from CAN height) 6 Stop signal (from CAN height)
7 Excessive motor temperature - Lift speed reduction
9 Reach back inhibited. Used either for "fork park" or for a UPA version of the module, a"Reach Back Inhibit" exists when the forks are below a certain height 10 Lift inhibited (pin 102)
11 Battery discharge indicator cut-out active (lift speed affected) 12 Special interlocks apply (UPA 2 & 3)
15 Battery approaching low (torque limitation active) 16 Lift in calibrate mode
17 The reach limit(s) are not programmed, reach in calibrate mode
18 There was no valve detected during the POWER ON checks. (assume no mast and there-fore no pump) 20 Battery unlatched - lift lower interlocks apply (no lower / slow lift)
HYDRAULIC WARNING CODES 119 The calibration value for the joysticks has been corrupted 120 Lift valve open circuit.
121 Lower valve open circuit 122 Control valve open circuit 123 Select valve open circuit
