Fault 39: Master TEC Internal Error

InfoCenter Display:
Fault Description
This fault is reported when the primary TEC detects an internal hardware fault.
Circuit Description
The primary TEC monitors the condition of various machine switches and sensors (inputs) and directs electrical
power to control machine functions (outputs) based on the state of the inputs. The primary TEC is primarily
responsible for managing the engine start signal and interlocks.
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
