Pinpoint Test

Description
Pinpoint tests are step-by-step diagnostic tests used to isolate the cause of a driveability symptom or system fault. The pinpoint test steps include references to specific for component inspection and testing, references to the Vehicle/Diagrams for circuit routing and electrical component locations, testing of engine control components (relays, switches, sensors, and solenoids), and basic circuit checks.

NOTE:
^ Vehicle inspection and preparation should be performed before starting any pinpoint test.
^ Always turn the key to the OFF position unless directed otherwise by the pinpoint test.
^ After the fault has been isolated and the correct repairs have been made, restore the vehicle, clear DTCs, rerun Diagnostic Quick Test, remove all test equipment, and reconnect all components.
