Dim on headlight not working, changed fuse,bulb,relay 15016745,and bulb connector,still want work-2002 trailblazer


Low beam's don't work , how about high beams . Low beam relay is turned on by the BCM - body control module , headlamp switch is a input to the BCM . Your best bet mite be to take it to a qualified repair shop , rather then guessing an replacing parts you don't need . Hooking up a scan tool an checking for DTC'S - diagnostic trouble codes should have been the first step before replacing parts .
The headlamp driver module (HDM) is an electronic module that provides electrical power to the vehicle low beam headlamps. The HDM is controlled by a pulse width modulated (PWM) ground signal from the body control module (BCM). The BCM determines the desired lamp intensity using the ambient light sensor, multifunction switch , wiper motor, and the park brake switch as inputs. In general, the HDM will operate in one of three modes:
• Reduced Intensity Mode: This mode is used by features that do not require or allow maximum low beam headlamp intensity such as daytime running lights (DRL) (nominal: 81% duty cycle).
• Full Intensity Mode: This mode is used by features that require full low beam headlamp intensity such as low beam headlamp operation in manual, wiper activated headlamp (WAH), or auto modes (nominal: 100% duty cycle).
• Off Mode: This is the default mode of the system that will occur when none of the features described above are active. The BCM will deactivate its PWM output (0% duty cycle) during this mode.

I am looking for timer instructions for a Defiant brand outdoor heavy duty digital timer. Has option for three plugs at the bottom. I do not know model number. I can't figure out these "modes"!!!


a mode is a operation program in the computer
for example mode 1 is timer time
mode 2 is set adjusted time
mode 3 no of sprinklers on mode 4 set
mode 5 etc
the mode is used to move from one program to another and once a change is made in that setting the mode button then saves that setting
all of this would be explained in the operators manual

Headlight low beam on my envoy 2006 not working


The headlamp driver module (HDM) is an electronic module that provides electrical power to the vehicle low beam headlamps. The HDM is controlled by a pulse width modulated (PWM) ground signal from the body control module (BCM). The BCM determines the desired lamp intensity using the ambient light sensor, multifunction switch and the park brake switch as inputs. In general, the HDM will operate in 1 of 3 modes:
?€¢
Reduced Intensity Mode: This mode is used by features that do not require or allow maximum low beam headlamp intensity such as daytime running lights (DRL) (nominal: 85% duty cycle).


?€¢
Full Intensity Mode: This mode is used by features that require full low beam headlamp intensity such as low beam headlamp operation in manual or auto modes (nominal: 100% duty cycle).


?€¢
Off Mode: This is the default mode of the system that will occur when none of the features described above are active. The BCM will deactivate its PWM output (0% duty cycle) during this mode.

The normal battery voltage input to the HDM must be between 6 and 16 volts DC to operate. Any deviation to these values could cause improper operation.
Major components of this system are the BCM, HDM, ambient light sensor, multifunction switch, park brake switch and low beam headlamps.
DTC B2575 Headlamp Control Circuit
When the body control module (BCM) senses a request for headlamp or daytime running lamp (DRL) illumination, the BCM sends a pulse width modulated (PWM) ground signal to the low beam headlamp driver module through the low beam headlamp driver module control circuit. The low beam headlamp driver module will illuminate the headlamps, adjusting the intensity based on the PWM signal received
You best bet is to take your vehicle to a ASE certified repair shop or the dealer >

The ambient light sensor is a light sensitive transistor that varies its voltage signal to the body control module (BCM) in response to changes to the outside (ambient) light level.
You should have the modules scanned for codes first off. Not the engine control module .( BCM ) body control module , yes . That's the first thing I always do !
Could be a bad ambient light sensor or the headlamp driver module. You could check voltage at the battery with engine running, should be over 14 volts. If you don't deal with this sort of thing on a regular basis I'd take it to someone who does !

HOW TO RESET ERROR CODE 04-562


Not a copier guy here BUT came up with this
1) From here
http://www.copytechnet.com/forums/xerox/43094-error-04-562-workcenter-pro-c3545-print.html
It sounds like 'Image Belt Transfer' whatever that is.
'you can enter in serice mode on this model only with laptop and xerox wcp diagnostic navigator'
2) from Zerox here. http://www.support.xerox.com/support/workcentre-pro-c2128-c2636-c3545/support/enus.html click on fault code search , put in code.and......
'Needs further customer support.'

Sounds like a 'belt' inside the machine broken or faulty.
Hope this assists you.

Try taking your memory out and resitting it, then if that doesn't work try the same thing with your harddrive.

I got a output voltage of 100.1 on a trace dr3624


The rms voltage is what counts, because it tells how much power the output will deliver to a resistive load. Inexpensive multimeters on their AC ranges are usually average-responding rms-calibrated meters. This means they measure the average of the absolute value of the AC component of the signal, and display that average multiplied by about 1.11 (actually, pi over sqrt(8)), the ratio of rms to average value for a pure sine wave. That way, the meter will give the right rms reading for a sine wave.

If the signal is a square wave, where the average and rms values are equal, the average-responding meter will read 11% too high.

Many inverters put out a modified sine wave (MSW), which sits at zero for a while, goes to a constant positive level for a while, goes back to zero for a while, and goes to a constant negative level for a while to complete the cycle. The positive and negative parts of the signal have the same magnitude and duration.

The rms and average values of an MSW depend on its duty cycle D, the fraction of a cycle for which the signal is not at zero. In a well-designed inverter, the duty cycle will be adjusted when the DC input voltage goes up and down to maintain the nominal rms output voltage. If we use peak voltage Vp to mean the magnitude of the positive and negative voltages the signal goes to, then Vavg for an MSW is equal to Vp times D, and Vrms is equal to Vp times the square root of D.

The duty cycle for which an MSW will have the same rms to average ratio as a sine wave is 8 over pi squared, or 81%. For any duty cycle less than this, an average-responding meter will read a lower voltage than the inverter rms output, and for a duty cycle higher than this, the meter will read too high.

If your MSW inverter is putting out 120 volts rms and its duty cycle varies from 50% to 75%, the meter reading will vary from 94 volts to 115 volts. I avoid the problem by using a Radio Shack 22-174B true rms digital multimeter.
