Where is located the ground wire on mazda mpv 2001?
Your ground wire connection for the OBD2 connector is located under the dash just below and to the right of the heater controls. More likely that you dont have power to the connector. Check the 10 amp "ROOM" fuse in under dash fuse box.
My car vibrate at 100-120km/hr
This is due to poor settings of the wheel bearings,tyres,- check balancing once again, wheel drums/ brake pads,suspension , joints and steering.
In all the entire front suspension must be checked, the WHELL ALIGNMENT must be checked with precision and each of the wheels must be checked for damage on hub, axle or chassis.
A TNS fuse is clicking when the ignition switch is off but when i go to ACC the clicking stops. What does this fuse do and what does it stand for and 3 what can I do to get this fixed
It is not a fuse, it is a relay.
- TNS controls parking lights, tail lights and running lights.
- Not sure what TNS stands for but my guess would be "Taillight, Night Running lights and Stop light"
- Normally the TNS relay is powered by the taillight fuse and is energized when the headlight switch is turned on
Having said that I'm not sure why it would be cycling when the ignition switch is off. Could be a short to ground somewhere in the system. If you have had any work done I would have it rechecked, especially if you swapped out radios or added extra lighting somewhere.
Other things you can try:
- Pull the taillight fuse. The TNS should not have power and the lights will not work.
- If the TNS is a removable type of relay pull it out and see if you still hear something clicking
- With the relay pulled check the base. The coil side should have 12vdc to ground on one side. the other side should not have continuity to ground with the headlight switch off.
- If there are other relays in the box of the same type, try swapping them out and see fir the problem follows the relay.
While these things will not fix the problem it may help diagnose the underlying problem.
