Driver Information System: Diagnosis Nissan Versa I

SELF-DIAGNOSIS MODE FUNCTION

1. Self-diagnosis can check for continuity between meter control circuit and each meter (speedometer, tachometer and fuel gauge).
2. Self-diagnosis can check for ODO/trip meter and A/T indicator (with A/T) or CVT indicator (with CVT) segment, low-fuel level warning lamp, low water temperature indicator lamp, and high water temperature warning lamp.

1. Turn the ignition switch ON, and switch the ODO/trip meter to "trip A" or "trip B". NOTE: If the diagnosis function is activated with "trip A" displayed, the mileage on "trip A" will indicate "0000.0", but the actual trip mileage will be retained. (The same applies for "trip B").
2. Turn ignition switch OFF.
3. While pushing the ODO/trip meter switch (1), turn the ignition switch ON.
4. Confirm that the trip meter displays "0000.0".
5. Push the ODO/trip meter switch at least 3 times. (Within 7 seconds after the ignition switch is turned ON.)
6. All the segments on the ODO/trip meter, and simultaneously the low-fuel warning lamp indicator illuminates. At this time, the unified meter control unit is turned to self-diagnosis mode. M/T MODELS (1) A/T AND CVT MODELS (2) NOTE: Check combination meter power supply and ground circuit when self-diagnosis mode of combination meter does not start. Replace combination meter if normal. Refer to " «COMBINATION METER»(ref-337620-S00700295732009080600000) ". If any of the segments is not displayed, replace combination meter. Refer to " «COMBINATION METER»(ref-337620-S00700295732009080600000) ".
7. Each meter activates while pressing ODO/trip meter switch. (At this time, the low-fuel warning lamp turns off, low water temperature indicator lamp and high water temperature warning lamp turn on.) NOTE: If any of the meter and gages are not activated, replace combination meter. Refer to " «COMBINATION METER»(ref-337620-S00700295732009080600000) ".
