Pinpoint Test Instructions

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 component inspection and testing, references to the 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, complete Powertrain Control Module (PCM) reset to clear Diagnostic Trouble Codes (DTCs), rerun Quick Test, remove all test equipment, and reconnect all components.
