I have the same problem. The only way to get the TV to come on is to unplug it, but once you get it back on it turns itself off again in a few minutes.

you have to reset the ecm code , when you removed the fuse the ecm registered this as a loss of voltage and threw a code so now it doesn't know that the fuse has been replaced. you need a scan tool to reset the ecm...please rate the solution...thanks

the first place to start is the flashing engine lite. that means cylinders are not firing at all or improperly and driving it like that for even short period could cause heavier damage. particularly valves and cat converter(s) the computer really needs to be scanned for codes in order to proceed. did the oil lite come on before or after engine quit. after engine quit would be normal cause it stalled. its possible that it needs spark plugs and/or coils. or more

SOURCE: My Fujitsu ScanSnap S510 only flashes 5 blue lights

I got off the phone with Fujitsu and i was told you need to make sure that the ScanSnap Icon is in the system tray without a Red Line cross through it, so if it is not in your system tray start the snap scan program, if it's disabled re-enable it and you should be good.

You may have dying power supply which you will have to do some checking, look for DC filter caps with leaking/bulging top, brown burt spots on the board, etc.

I have no fuses blown under hood or in fuse panel on dash side code scanner will not power up or work at all


With key in on do you have all dash warning lamps on, and the check engine light is on? If that's all okay, and still nothing on the scanner, it is possible the wiring to the diagnostic port got messed up. You would need a wiring diagram to really see the wires involved. By the way what year is your vehicle? All after 1996 have the same obd-2 connector. There were some variations leading up to the '96 model year. I recall some dismayed GM owners of '94 & '95 models, especially luxury class models, that had obd-2 connectors and obd-1 diagnostics, same as all the early '90's GM vehicles. Back then, GM and Chrysler were always a step ahead of Ford, beginning in the early '80's. ! enough nostalgia, did u figure it out with your scanner?

Car wont start, changed ecm, plugs, started but died, what should i do


After you put in the ecu, do the crank relearn, and you're good to go.
Ensure that your battery is fully charged before attempting the relearn procedure. Do not leave any battery charger or jumper cables attached to the battery. Close the hood completely. Some applications require that the doors remain closed during the procedure.
96-99 GM
1. Rotate the key to the start position to attempt to start the vehicle (the vehicle will not start).
Allow the key to return to the all position (same as if the vehicle would have started). The theft system light will flash (or stay lit) on the dash for approximately 10 minutes.
2. When the theft system telltale stops flashing (or turns oft) turn the key to the off position for 5 seconds and then attempt tostart the vehicle. The vehicle should start on this cycle.
3. Once the vehicle is running, the password relearn is complete.

3. When the theft system telltale stops flashing (or turns off) turn the key to the off position for 5 seconds and then attempt to start the vehicle.
4. Repeat steps 1 through 3 two more times for a total of 3 cycles/30 minutes.
5. On the next cycle of turning the ignition key from off to crank the vehicle should start
6. Once the vehicle is running, the password is learned and this completes the cycle.
7. Clear any DTC's with a scan tool if necessary. DTC history will be cleared after 100 ignition cycles.

How do i unlock a 2004 gm radio?


GM tech II scanner will unlock (calibrate) this stereo. some automotive shops that specialize in electronics will have this scanner or you will have to go to GM dealer.

Code of radio


there is no such thing for your van. the stereos in your van are coded through a data calibration system. If stereo is switched with a different one, most poeple will change the stereo due to the display being out. when this happens, you will need a GM tech II scanner in order to recalibrate the unit into your vehicle. some dealers will charge anything from free to 1/2 hour to calibrate the stereo. to save time you should install the radio into the van, because the calibration is done through thr OBDII connector under dash.

How do i clear the "service engine soon"


Disconnect the battery for a minuit and turn on the light's to power down any electrical power. Reconnect the battery and that should clear the "servie engine light soon",but if there are any DTC codes, the "Service engine light" will come back on.
On board diagnostic (OBD) was designed on vehicles equipped with electronic fuel injection so you can generally retrieve the codes yourself. No need buying a scanner or running to any parts stores to check the Engine Light. This system is called obd1 and applies to most vehicles made before 1995 for domestics and 1993 on imports.

For GM domestic vehicles made before 1995, the diagnostic connector is located under the dash panel by the driver side. To get the check engine codes to flash in your dash panel, use a jumper wire or a paper clip and connect terminals A and B of the diagnostic connector. Turn your ignition key on with engine off and the codes should start to blink. All codes should start with code 12 which is one long flash followed by 2 short flashes. This code 12 means the diagnostic system is normal and will repeat itself continuously if there are no trouble codes. Otherwise, code 12 will flash 3 times before flashing the fault codes.

the codes can be erased or cleared by disconnecting the battery negative terminal for 1 minute and reconnect. Just make sure to check your service manual in case you have electronic equipment such as radio or clock that needs reprogramming in which battery disconnection is not recommended. Finally after performing repairs on the culprit code, always go for a road test to confirm if the problem is fixed.

Good luck and hope this help, here is a link to the DTC codes. http://www.gmtuners.com/OBD1_DTC.htm
