2004 Scion xA Service and Repair Manual

This service and repair manual is built around the 2004 Scion xA specifically — the 1.5L four-cylinder (1NZ-FE), in either trim Scion listed for the year — so the clearances, torque values and service procedures you follow are the ones written for your car rather than figures approximated from an adjacent model year.

Known issues on the 2004 xA. Two recalls are on federal record for this vehicle. The first covers the air bag control module: the control module for the supplemental restraint system (SRS ECU) may experience an internal short, possibly causing the air bags to unintentionally deploy, or become deactivated. If the air bags and/or seat belt pretensioners unintentionally deploy, it can increase the risk of a crash; if they are deactivated, it can increase the risk of injury in the event of a crash. The second covers the cruise control, where certain Rostra units installed as original equipment on Gulf States Toyota and Southeast Toyota Scion vehicles, and also sold as aftermarket equipment, may not return to idle when the on/off switch is pressed for the first time; failure to release the throttle when the cruise control is turned off could result in a vehicle crash. Owners have filed 20 complaints for the year and Scion has issued 17 technical service bulletins. The diagnostic and repair procedures behind those systems are here.

Servicing the supplemental restraint system, checking a cruise control fault or working through a scheduled service, it keeps you on the OEM procedure and the correct specification for this 2004 xA.
