Check your alternator, if you recently had it replaced - make sure that the one you got is correct, if your working on your own.. take a volt meter, set it to dc volts and measure across the battery while the car is running, generally you see around 14 volts, 12+ volts from the battery always and the alternator adds around 2 while running - the weird smell you smell if it smells like a dying rat, it would sound like you will need an alternator - as for your brakes, I'd start by checking the parking brake lever - back to your battery light, make sure all connectors are good on the alternator and also if your alternator does measure 14 volts, turn on all acessories - wipers headlights, radio, blower, rear defogger - this will generate what we call a load, if you then go to your battery you should see the battery voltage not drop below around 13.5 if it does, you probably need an alternator because it's failing to meet the demands of your car. though the lights come on together, it doesn't necessarily mean their in the same circuit - I had the exact same problem with a nissan altima of that year, that came into the shop... all its bulbs were burnt out and it kept having that happen, then other times it was just fine! give that a try, if that doesn't work send me an email at email@example.com I'd be glad to give you advice!

Your alternator is dead/dying. Nissan puts both of those lights on to tell you that the alternator isn't charging your battery.

Crankshaft and Camshaft Position Sensors
Camshaft Position Sensor
Engine timing is determined from the relationship between the crankshaft and camshaft. This relationship is maintained by a timing chain or timing belt. The Engine Management System does not control engine timing but it does monitor the relative position and speed of these shafts by monitoring signals generated by sensors. The Engine Management System (EMS) uses signals generated by the camshaft position sensor to synchronize fuel injection to the valve sequence and for the on-board diagnostic procedure for misfire detection. The EMS energizes the injector at or near the time the intake valve opens. For misfire diagnosis, the EMS compares the number of camshaft sensor reference pulses and the number of crankshaft position sensor reference pulses received. If the EMS receives an incorrect number of pulses Diagnostic Trouble Codes (DTC’s) should be stored in the EMS.
If the camshaft position sensor or circuit is faulty most engines will start. Some engine management systems will then default to a pre-programmed injector firing sequence. All injectors may be energized simultaneously or all of the injectors on one bank may be energized at the same time. If the CMP data is required for misfire detection and reliable CMP data is not present misfire detection would probably be suspended.
Related Symptoms The following symptoms can be caused by an intermittent wiring connection or faulty signal to the EMS:
In addition the EMS uses minute variations in the CKP sensor data to determine engine misfire. The EMS uses this information in conjunction with the camshaft position sensor to perform misfire diagnostics.
Related Symptoms: No Start/Intermittent Start Condition – Can be caused by a faulty crankshaft position sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit

Check your brake fluid level in the engine compartment. Its located on the rear RH side of the engine compartment, its a white/clear resevoir connecting to a large black circular object. If the fluid is low, fill to proper level, also I would recommend having your brake system checked as there may be a leak. If the fluid is fine and at the proper level, you may have a damaged/broken brake fluid level sensor or damaged/broken Emergency brake switch. Hopefully this helps....please rate thanks!!
