DIAGNOSTIC INFORMATION AND PROCEDURES DIAGNOSTIC STARTING POINT - ENGINE MECHANICAL Begin the system diagnosis by reviewing the DISASSEMBLED VIEWS, ENGINE COMPONENT DESCRIPTION, Drive Belt System Description , LUBRICATION DESCRIPTION and NEW PRODUCT INFORMATIONand . Reviewing the description and operation information will help you determine the correct symptom diagnostic procedure when a malfunction exists. Reviewing the description and operation information will also help you determine if the condition described by the customer is normal operation. Refer to Symptoms - Engine Mechanical in order to identify the correct procedure for diagnosing the system and where the procedure is located. SYMPTOMS - ENGINE MECHANICAL Strategy Based Diagnostics 1. Perform a DIAGNOSTIC SYSTEM CHECKS in Engine Controls before using the symptom tables (if applicable). 2. Review the system operations in order to familiarize yourself with the system functions. Refer to DISASSEMBLED VIEWS, ENGINE COMPONENT DESCRIPTION, Drive Belt System Description , LUBRICATION DESCRIPTION and NEW PRODUCT INFORMATION. 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. Visual/Physical Inspection  Inspect for aftermarket devices which could affect the operation of the Engine. Refer to CHECKING AFTERMARKET ACCESSORIES in Wiring Systems.  Inspect the easily accessible or visible system components for obvious damage or conditions which could cause the symptom.  Check for the correct oil level, proper oil viscosity, and correct filter application.  Verify the exact operating conditions under which the concern exists. Note factors such as engine RPM, ambient temperature, engine temperature, amount of engine warm-up time, and other specifics.  Compare the engine sounds (if applicable) to a known good engine and make sure you are not trying to correct a normal condition. Intermittent Test the vehicle under the same conditions that the customer reported in order to verify the system is operating properly.
