Input and output signals must always be correct and stable in the operation of the A T system The A T system must be in good operating condition and be free of valve seizure solenoid valve malfunction etc It is much more difficult to diagnose a problem that occurs intermit tently rather than continuously Most intermittent problems are caused by poor electric connections or improper wiring In this case careful checking of suspected circuits may help prevent the replacement of good parts A visual check only may not find the cause of the problems A road test with CONSULT II or GST or a circuit tester connected should be performed Follow the Work Flow Refer to Before undertaking actual checks take a few minutes to talk with a customer who approaches with a driveability complaint The cus tomer can supply good information about such problems espe cially intermittent ones Find out what symptoms are present and under what conditions they occur A Diagnostic Worksheet like the example AT 55 should be used Start your diagnosis by looking for conventional problems first This will help troubleshoot driveability problems on an electronically controlled engine vehicle Also check related Service bulletins AT 53 Gl MA EM LG EG GL MT ST RS SC EL DX TROUBLE DIAGNOSIS INTRODUCTION Introduction Cont d DIAGNOSTIC WORKSHEET Information From Customer KEY POINTS WHAT
