Fault 4: Input Pull-Up Enable (Ipe) Voltage Too Low - Toro Reelmaster 5010-H Diagnostic Manual

Fault 4: Input Pull-Up Enable (IPE) Voltage
Too Low
InfoCenter Display:
Fault Description
Inputs for the TEC-5002 controller are bad. The Input Enable Pull-up (IPE) check on the TEC-5002 has failed.
Circuit Description
The internal TEC-5002 input pull-ups are not being properly powered.
Conditions for Setting the Fault
If the input pull-ups are not being properly powered on the circuit board for the TEC-5002 controller, the inputs
and outputs do not function and the TEC-5002 reports a fault 4.
Recommended Service Actions
Step 1: Verify that the fault repeats.
1. Clear the system faults from the InfoCenter. Refer to
2. Operate the machine.
Pass The fault did not repeat. Go to
Note:
If the fault does not repeat, an isolated event has occurred.
Fail The fault repeated. Go to Step 2.
Because the TEC-5002 controller is a solid-state component, there is no method to test it directly. The
TEC-5002 may be damaged if you attempt to test it with electrical test equipment, such as a digital multimeter.
Step 2: Replace the TEC.
Note:
TEC controllers are programmed to specific machine model and serial numbers. TEC controllers do not
function until programmed by Toro DIAG.
There are three procedures that you need to accomplish as part of replacing a TEC. Refer to
Electronic Controller (TEC) (page
1. Use Toro DIAG to save the machine timers and counters file out of the machine. (page 26)
2. Replace the TEC-5002. (page 26)
3. Use Toro DIAG to Program the TEC-5002. (page 27)
4. Go to Returning the Machine to Service (page 22)
