Fault 29: Master Board Internal Error

InfoCenter Display:
Fault Description
This fault is reported when the primary TEC detects a hardware fault in one of its output circuits. The output
circuit is shut off but current flow is still detected.
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.
