Testing EA/CC/ISC Systems
LH and HFM fuel management systems have a separate module that controls the electronic
actuator, cruise control, and idle speed control (EA/CC/ISC). The ME control module on 1996
and later vehicles integrated all operations into the ME control system.
The exact Electronic Actuator (EA), Cruise Control (CC), and Idle Speed Control (ISC) module
variations (i.e., EA/CC/ISC, CC/ISC, and ISC) are dependent on installed options like cruise
