I HAVE A 2008 IMPALA I JUST GOT A NEW ALT,AND BATTERY BATTERY SAVER ACTIVE COMES ON AFTER IT RUNS A FEW MIN WHAT COULD THE PROBLEM BE


Electric Power Management
The vehicle has Electric Power Management (EPM) that estimates the battery's temperature and state of charge. It then adjusts the voltage for best performance and extended life of the battery.
When the battery's state of charge is low, the voltage is raised slightly to quickly bring the charge back up. When the state of charge is high, the voltage is lowered slightly to prevent overcharging. If the vehicle has a voltmeter gage or a voltage display on the Driver Information Center (DIC), you may see the voltage move up or down. This is normal. If there is a problem, an alert will be displayed.
The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles. This is because the generator (alternator) may not be spinning fast enough at idle to produce all the power that is needed for very high electrical loads.
A high electrical load occurs when several of the following are on: headlamps, high beams, fog lamps, rear window defogger, climate control fan at high speed, heated seats, engine cooling fans, trailer loads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the battery. It does this by balancing the generator's output and the vehicle's electrical needs. It can increase engine idle speed to generate more power, whenever needed. It can temporarily reduce the power demands of some accessories.
Normally, these actions occur in steps or levels, without being noticeable. In rare cases at the highest levels of corrective action, this action may be noticeable to the driver. If so, a Driver Information Center (DIC) message might be displayed, such as BATTERY SAVER ACTIVE, BATTERY VOLTAGE LOW, or LOW BATTERY. If this message is displayed, it is recommended that the driver reduce the electrical loads as much as possible. See DIC Warnings and Messages.

Chek apears on dashboard


You would need to know which warning light you are dealing with.
CHECK could be a check engine light, or check gauges light.
A check engine light means the computer sees a problem with the performance of the engine that can affect fuel mileage or emissions.

2000 Land Cruiser flashing check engine light and the car is running rough/shuddering


The warning light is telling you the computer has found a problem that is affecting engine performance and fuel mileage. A flashing light means it is something serious.
You should have someone scan the computer for trouble codes and go from there. The codes will help direct the mechanic as to what to test.

Engine warning light


Hello and welcome to fixya.com
turned on by the systems computer it is to alert you to the fact that the computer module has detected a fault in the systems operation, this can be the engine, the emissions system or the transmission. What must be done now is to have the system scanned for fault codes, these are called OBD2 fault codes, then diagnostics are performed to determine the cause of the fault codes and repair made based on the diagnostics performed.

My 2007 Dodge cummins 6.7 is telling me to perform service and the catalyst is full. How do I fix this problem myself?


Intervention Regeneration Strategy - EVIC
Message Process Flow (Catalyst Full Message)
(6.7L Diesel Engines Only)

Your new Cummins 6.7L diesel meets all EPA Heavy
Duty Diesel Engine Emissions Standards, resulting in the
lowest emitting diesel engine ever produced.
To achieve these emission standards your vehicle is
equipped with state of the art engine and exhaust system.
The engine and exhaust aftertreatment system work
together to achieve the EPA Heavy Duty Diesel Engine
Emissions Standards. These systems are seamlessly integrated
into your vehicle and managed by the Cummins
6.7L engine Powertrain Control Module (PCM). The PCM
manages engine combustion to allow the exhaust system's
catalyst to trap and burn Particulate Matter (PM)
pollutants, with no input or interaction on your part.
Additionally, the overhead console in your vehicle has
the ability to alert you to additional maintenance required
on your truck or engine. Refer to the following
messages that may be displayed on your Electronic
Vehicle Information Center (EVIC):

WARNING!
A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.

Perform Service
The 6.7L Cummins engine utilizes a Closed Crankcase
Ventilation (CCV) system, EGR Valve and a EGR Cooler.
This system filters and recycles gasses produced in the
crankcase during the normal combustion process. Perform
Service will be displayed on the overhead console of
your vehicle if the CCV filter, EGR Valve and EGR Cooler
is due for required maintenance. The CCV filter is located
on the top of the engine valve cover. For additional
information, see your local authorized dealer.
Catalyst Full See Owner Manual
Catalyst Full See Owner Manual will be displayed on the
overhead console of your vehicle if the exhaust particulate
filter reaches 80% of its maximum storage capacity.
Under conditions of exclusive short duration and low
speed driving cycles, your Cummins engine and exhaust
aftertreatment system may never reach the conditions
required to remove the trapped PM, if this occurs Catalyst
Full See Owner Manual will be displayed on the
overhead console in your vehicle. If this message is
displayed you will hear one chime to assist in alerting
you of this condition.
Catalyst Stat::::::::::80%
Catalyst Stat::::::::::80% will replace the message Catalyst
Full See Owner Manual after it is displayed for one
minute. The engine Powertrain Control Module (PCM)
will continue to monitor the amount of particulate matter
trapped in the particulate filter. This message indicates
the percentage of the particulate filter capacity that has
been used.

By simply driving your vehicle at highway speeds for as
little as 45 minutes you can remedy the condition in the
particulate filter system and allow your Cummins engine
and exhaust Aftertreatment system to remove the
trapped PM and restore the system to normal operating
condition.
Catalyst Stat:::::::::::80%, 90%, 99%
Catalyst Stat:::::::::::80%, 90%, 99% If you are unable to
drive your vehicle under these conditions for an extended
period of time after the initial warning notification,
the Engine PCM will continue to monitor the
particulate filter and will display the progression of
particulate filter usage (80, 90, 99%) on the EVIC message
center.

CATALYST FULL SERVICE REQD
If the particulate filter reaches 99% of it's capacity the
overhead console in your vehicle will chime twice and
display the message CATALYST FULL SERVICE REQD.
At this point the engine PCM will register a fault code,
the instrument panel will display a MIL light and the
engine PCM will derate the truck reducing its horsepower
and torque output.
The PCM derates the engine in order to limit the likelihood
of permanent damage to the aftertreatment system.
If this condition is not corrected and a dealer service is
not performed, extensive exhaust aftertreatment damage
can occur. In order to correct this condition it will be
necessary to have the truck serviced by your local
authorized dealer.

What does the master warning light mean? (triangel with ! and the three lights points to the car).


This light shows operational status of traction control system. If it is constantly lit when engine is running, this means that traction control system is off. If the light flashes during driving, it means the loss of traction at the wheels, and traction control system is operating- decreasing engine torque to stop exessive wheelspin.
Good luck.

What does perform service service indicator light came on,what does that mean. 20.400 miles oil was changed @20,200 mikes


Perform service indicator warning is a heads up that another oil change is needed. Your vehicles computer calculates a duty cycle for service intervals; Driving distance, stop and go etc... Change the engine oil, and reset the alert, and you'll be fine.

A message stating service B in 500 miles


Service B means that there is a major service due. Brakes are not related. You will get a break warning light when they are due. The B service includes Oil and filter, Interior dust filter, Tire rotation, check of all the fluids, Lubricate all door and trunk hinges, and engine air filter. Also brake flush every 2 years.
