Diagnostic Flash Code Listings
The Diagnostic Process
  • Establish the type of control system fitted to the vehicle.
  • Confirm there is a trip, or has been an intermittent trip.
    To do this firstly observe the control system's TruCharge (battery gauge) display. This will behave as described below.

    Flashing Rapidly
    The control system is tripped.
    Connecting a programmer to the control system while this is happening will give you a trip code.
    Click here to diagnose the Trip Code.

    Flashing Slowly
    No trip is currently detected by the control system. The slow flash is an indication that the batteries require charging.
    A trip may have occurred previously, connect a programmer, view the System Log and make a record of the Trip Codes.

    Display is steady
    No trip is currently detected by the control system.
    A trip may have occurred previously, connect a programmer, view the System Log and make a record of the Trip Codes.
    Click here to diagnose the Trip Code.

    Display does not illuminate
    No power is reaching the control system.
    Ensure the batteries are fully charged and that all connections between batteries and the control system are made. If these connections are good, then the entire control system should be returned to PGDT.

    NOTE: If the Vehicle has a single lamp/LED Status indicator then the information above is still relevant, with the exception that the Lamp/LED will repeat flash a Trip code by flashing a number of times rapidly and repeating the flash after a short period of time.
    EG: Flash..Flash..Flash.. pause........Flash..Flash..Flash.. - This represents a three bar Trip

    Actuators do not respond
  • If the vehicle has more than one actuator, check to see how many are not working.
  • Check that all connections between the control system and the actuator motors are correct.
  • Check that the actuator motor is not faulty.
    This can be achieved by disconnecting the control system and routing power straight to the Actuator motor in question.
  • If the actuator motor is not faulty check the connections between the control system modules are correct.
    If the connections are good, then in the case of Pilot+: the ALM should be returned to PGDT for investigation.

    Lights do not respond
  • Check that all connections between the control system and the lights are correct.
  • Check that the bulbs are all in good working order.
    Replace any blown bulbs and check the system to see if this has cured the problem.
  • If the lighting circuit is not faulty check the connections between the control system modules are correct.
    If the connections are good, then in the case of Pilot+: the ALM should be returned to PGDT for investigation.
    In the case of VSI The Lighting Module should be returned to PGDT for investigation.

    Number of lights flashing
    PILOT CONTROLLER
    PILOT +
    10
    High supply voltage
    2 flash then pause
    9
    Automatic (solenoid) brake fault
    5 flash then pause
    8
    Probable fault on controller
    6 flash then pause
    7
    Probable fault on controller (joystick)
    6
    Charger or inhibit active
    5
    Right motor fault (shorted to supply)
    4 flash then pause
    4
    Right motor fault (open circuit)
    3
    Left motor fault (shorted to supply)
    3 flash then pause
    2
    Left motor fault (open circuit)
    1
    Low supply fault
    1 flash then pause
    Pilot + 7 flash then pause = joystick out of Neutral -turn off then on again to clear
   
   
   
   
    OTHER CONDITIONS

This part covers conditions that are not displayed as trip codes or on the TruCharge display. This may be because:
  • Either the control system cannot switch on,
  • the condition is not considered critical enough to force a "trip",
  • or the control system cannot detect the condition.

    Control System Will Not Switch On
  • Check the battery connections to the control system. If these appear to be good, then the control system may be defective.

    Vehicle Drives Slowly OR Not at all
    This could be caused by one of the following:
  • The control system has been incorrectly programmed.
  • A speed limiting function is active, e.g. seat in a raised position on vehicles fitted with lifting seats.
  • Defective motor or defective brake.

    Vehicle Will Not Drive in a Straight Line
  • This could be caused by a defective motor or defective brake.

    One Motor or Brake becomes Very Warm
  • This could be caused by a defective motor or defective brake.

    Batteries Discharge Very Quickly
    The batteries can discharge very quickly for several reasons, these described below.
  • Worn or damaged batteries - check battery condition.
  • Charger defective or incorrect charger being used - check charger operation (refer to vehicle's operating manual).
  • Incorrect batteries being used - refer to vehicle manufacturer's instructions for correct battery types.
  • One motor or brake jamming.
    Ambient temperature has a significant effect on battery capacity. Therefore, if the temperature is lower than normal the wheelchair's range will be reduced. In this situation, the TruCharge battery gauge still gives an accurate state-of-charge reading.
