Fault Code
Fault Description
33 Forward piston (traction) pump output has open or short to ground
34 Reverse piston (traction) pump output has open or short to ground
35 Reverse engine cooling fan output has open or short to ground
39 LH PTO output has open or short to ground
40 RH PTO output has open or short to ground
41 Solenoid valve S1 (GM 4700−D lift/lower enable) output has open or short to
ground
42 Solenoid valve S2 (GM 4700−D LH deck raise) output has open or short to
ground
43 Solenoid valve S3 (GM 4700−D LH deck lower) output has open or short to
ground
44 Solenoid valve S4 (GM 4700−D LH deck float) output has open or short to
ground
45 Solenoid valve S5 (center deck raise) output has open or short to ground
46 Solenoid valve S6 (center deck float) output is faulty
47 Solenoid valve S7 (GM 4700−D RH deck raise) output is faulty
48 Solenoid valve S8 (GM 4700−D RH deck lower) output is faulty
49 Solenoid valve S9 (GM 4700−D RH deck float) output has open or short to
ground
50 Mow circuit PRV1 output has open or short to ground
51 Mow circuit PRV2 output has open or short to ground
52 Engine cooling fan output has open or short to ground
62 Counterbalance solenoid has open or short to ground
63 Traction pedal position sensor is returning a voltage higher than 4.75V or lower
than 0.25V (replace the traction pedal position sensor)
64 Traction pedal position sensor neutral switches do not align with calibrated
sensor values (recalibrate traction pedal position sensor)
65 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)
66 TEC controller overcurrent in traction circuit
67 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.
