Circuit Description

Throttle Actuator Control (TAC) module contains data which is essential for proper TAC system operation. TAC module continuously check integrity of this data.

When TAC module is unable to write or read data to and from RAM or TAC module is unable to correctly read data from flash memory or an internal TAC module processor fault is detected, DTC will set.

DTC will set when TAC module determines that an internal data test did not pass and condition is present for less than one second.
