Well since the lights are controlled by the OBD (on board diagnostics), you'll have to reset it. You may be able to do this by simply disconnecting the battery for a few hours. However, a lot of newer vehicles have electronically locked radios which require the manual to be able to be re-enabled.

I'd check out the radio before disconnecting the battery.

The only other ways are to physically disconnect the lights in the dash or get someone with an OBD reader to clear the codes.

SOURCE: 2002 Nissan Frontier. Vacuum problem


The windshield washer hoses have nothing to do with any electical componenents on the car. You simply won't get water to the windshield.

I suggest locating, and purchasing if necessary a repair manual for this truck. These newer engines have so many wires, and hoses and can be hard to trace.

All vaccum lines start from the engine area, tranny area, and lead to the firewall (back) and other compenants.

Start looking at different compenants that have small rubber hoses and try to trace them as far as you can. Search top and bottom, front and back, side to side. These hoses are sometimes linked with others by T's, and V's and such as vacuum operates several different components at once from one source.

I highly suggest getting a repair manual; CHILTON is the best, as it is more details and descriptive, and provides clear pictures to show particular components and such.

Please, let me know if you need any further assistance with this matter.

2004 Nissan frontier. Bypass hose replaced by a mechanic that had to remove the intake plenum. Now the check engine light is on. EGR is not getting vacuum. Brake booster looses vacuum when off.

It sounds like a vacuum leak either at the intake plenum or intake manifold, or egr valve.You might check all the vacuum lines to be sure they are all connected. But if it was not doing that before the mechanic worked on it I would take it back to him and say fix it. The check engine light is on because there is a vacuum leak and it's causing the egr valve and booster to not function properly.
