Strategy Based Diagnostics

Perform a «Diagnostic System Check - Vehicle»(/cadillac/srx/i-2003-2009/remont/oem-general-information/#vehicle-dtc-information) in Vehicle DTC Information before using the symptom tables, if applicable.
Review the system operations in order to familiarize yourself with the system functions. Refer to «Disassembled Views»(/cadillac/srx/i-2003-2009/remont/mechanical/#engine-mechanical-36l-ly7-introduction) , «Engine Component Description»(/cadillac/srx/i-2003-2009/remont/mechanical/#engine-mechanical-36l-ly7-introduction__engine-component-description) , «Drive Belt System Description»(/cadillac/srx/i-2003-2009/remont/mechanical/#engine-mechanical-36l-ly7-introduction__drive-belt-system-description) and «Lubrication Description»(/cadillac/srx/i-2003-2009/remont/mechanical/#engine-mechanical-36l-ly7-introduction__lubrication-description) .

All diagnosis on a vehicle should follow a logical process. Strategy based diagnostics is a uniform approach for repairing all systems. The diagnostic flow may always be used in order to resolve a system problem. The diagnostic flow is the place to start when repairs are necessary. For a detailed explanation, refer to Strategy Based Diagnosis in General Information.
