Engine cooling fan output has open or short to ground
Counterbalance solenoid has open or short to ground
Traction pedal position sensor is returning a voltage higher than 4.75V or lower
than 0.25V (replace the traction pedal position sensor)
Traction pedal position sensor neutral switches do not align with calibrated
sensor values (recalibrate traction pedal position sensor)
Traction pedal position sensor forward/reverse switches are indicating the pedal
is in both positions at the same time (replace the traction pedal position sensor)
TEC controller overcurrent in traction circuit
Traction current validation failure: make sure TEC forward traction output is
connected to the piston pump forward traction solenoid coil. If circuit is connec-
ted, replace the TEC--5002 controller.
