Mode V (Test Mode)
Mode V represents a real-time diagnostic test of the crank angle sensor, ignition signal, airflow output signal and fuel pump. This mode is accessed for an in-bay running test of the vehicle. The Red and Green LEDs must be monitored carefully during this test, with special attention paid to the number of flashes before each pause.
The malfunction code will be displayed only once and will not be stored in memory. If Green LED blinks on and off evenly, this indicates a fault in the crank angle sensor. If the Green LED flashes twice before a pause, this indicates a fault in the airflow meter. If the Green LED blinks 3 times before a pause, this indicates a fault in the fuel pump circuit. If the Green LED blinks 4 times before a pause, this indicates a fault in the ignition signal.
