where is the on-board computer (engine control module?) located?

The ECU is located rear right hand side passenger side of engine compartment.There was a recall and re-flashing bulletins for that car.There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online
