d.F
Code d.F: d.8 + d.4 + d.2 + d.1
Connect FlashWare and see if the versions for the Display, TPA, PPA, VM, and Armrest Board are displayed. If the Display is not shown, check connections to the Display. If OK, replace the Display. If the other devices are not shown, check connections to the VM from the Display. Verify power to the devices. If OK, replace the VM. If no devices are shown, check for shorts between the CAN High and CAN Low wires. Measure resistance between the CAN High and CAN Low pins going into the Display. The reading should be approx. 180 ohms. If open or shorted, replace the Display.
E1
Code E1: Incorrect Start Procedure for the Armrest Board or Levers One of the switches on the Armrest Board or one of the lever control switches is out-of-neutral prior to key ON or the seat switch or battery gate switches are closed.
Check the lever/fingertip controls for binding. Check the seat switch and battery gate switches. Test switches. Check resistance of resistor in static strap standoff; should be 200 to 250k ohm.
E2
Code E2: Lift Potentiometer (Lever Control) Out-of-Range Voltage from the lift pot is outside the expected operating range.
Check pot for binding. Make sure battery voltage is configured correctly. Learn pot. Test pot voltage. Check resistance of resistor in static strap standoff; should be 200 to 250k ohm. Verify configuration jumpers are in place on PPA. Check for shorts to frame. Set amplifier and VM defaults in FlashWare.
E3
Code E3: Tilt Potentiometer Out-of-Range Voltage from the tilt pot is outside the expected operating range.
Make sure battery voltage is configured correctly. Learn pot. Test pot voltage.
E4
Code E4: Sideshift Potentiometer Out-of-Range Voltage from the sideshift pot is outside the expected operating range.
Make sure battery voltage is configured correctly. Learn pot. Test pot voltage.
E5
Code E5: 4th Function Potentiometer Out-of-Range Voltage from the 4th Function pot is outside the expected operating range.
Make sure battery voltage is configured correctly. Learn pot. Test pot voltage.
