Mode V (Test Mode)

Mode V represents a real-time diagnostic test of crank angle sensor, ignition signal. This mode is accessed for an in-bay running test of vehicle. Red and Green LEDs must be monitored carefully during this test, with special attention paid to number of flashes before each pause.

Malfunction code will be displayed only once and will not be stored in memory. If Red LED blinks on and off evenly, a fault exists in crank angle sensor. If Green LED flashes twice before a pause, a fault exists in airflow meter. If Red LED blinks 3 times before a pause, a fault exists in fuel pump circuit. If Green LED blinks 4 times before a pause, a fault exists in ignition signal.
