Actuator Control Module Performance
– Poor connection – Check Throttle Actuator Control (TAC) module connector for water
– Faulty Throttle Actuator Control (TAC) module
– No response
The Throttle Actuator Control (TAC) module contains data which is essential for proper TAC operation. The TAC module continuously test the integrity of this data. When the TAC module is unable to write or read data to and from random access memory (RAM), or the TAC module is unable to correctly read data from the flash memory or and internal TAC module processor fault is detected and the Detected Trouble Code (DTC) is set.
