Quick Test: Notes

Quick Test is divided into specialized test procedures that are functional tests of EEC system. All tests are completely menu driven using New Generation Star (NGS) scan tool. The following procedures must be followed in sequence to avoid misdiagnosis:

• VISUAL CHECK 
• VEHICLE PREPARATION & EQUIPMENT HOOKUP 
• DIAGNOSTIC TEST MODE 
• SWITCH MONITOR TEST 
• CLEARING CODES 

Complete QUICK TEST before performing any system tests. Record any DTCs retrieved. Service DTCs in the order they are output. If servicing possible intermittent DTCs, retrieve any available freeze frame data. See FREEZE FRAME DATA MODE  under ADDITIONAL SYSTEM FUNCTIONS. After each service or repair procedure has been completed, always repeat QUICK TEST procedures to ensure all EEC systems are working properly and DTCs are no longer present.
