Il est possible de trouver un sch?ma de c?blage pour la radio d'usine GMC Arcadia AWD 2010 aupr?s d'un concessionnaire GMC ou un atelier de r?paration automobile agr??, ils ont acc?s aux manuels techniques et aux informations de c?blage pour les v?hicules GMC. Il est important de noter que les travaux de c?blage de l'?lectronique de voiture doivent ?tre effectu?s par des professionnels exp?riment?s, car une mauvaise manipulation peut causer des dommages au v?hicule et mettre en danger les passagers.
HYJACKER , GMC TRUCK<>?
no engine, no year or country told nor VIN(FAIL)
THE SERVICE MANUAL COVERS THAT. buy it?
AND DEPENDS ON ENGINE THERE, NOT TOLD
BUT IN GENERAL
THAT IS THE RELAY THAT POWERS THE PCM UP.
on some cars the relay is enabled by the IMMO. too.
there really is no need to worry this tech question
we read the manual.
check and test bcm which is located under drivers side rear seat fold it up and unit and harnesses are mounted on floor sometimes get damaged or corrosion--------- https://www.trailvoy.com/threads/unknown-driver-gauges-crazy-etc.100835/ -------------https://www.trailvoy.com/threads/not-solved-unknown-driver-no-p-lock-p-wind-radio-etc.143065/--------https://www.trailvoy.com/threads/not-solved-unknown-driver-no-p-lock-p-wind-radio-etc.143065/ --------file:///C:/Users/john/Downloads/Service%20Bulletin%201551460%20(3).pdf
THE CAR HAS LIKE 50+ ELECTRICS DEVICES,
ONE IS HEAD LAMPS THAT WORK KEY OFF DO THEY
IF NOT FIX DEAD HEAD LAMPS FIRST. FUSES.
IS STATER MOTOR DEAD
IS ENGINE DEAD
IS TRANSMISSION DEAD (ENGINE RUNS)
DOES DASH HEATER BLOWER WORK
DOME LIGHTS DEAD?
BRAKE LAMPS DEAD
TURNS DEAD
PARK LAMPS FRONT AND REAR AND SIDES DEAD/.
SEE, HOW COMPLEX 12DC POWER IS? AND MORE LOTS MORE. EVEN A DEAD RADIO
4wd ?
the service manual covers that A/T box
scan the PCM for TCM errrors> yet
and check fuses.
the transmission pages show how to do the pump pressure port test for PRNDL , all selected lever positions.(a hand gauge tool)
the shift linkage must be working correctly.
transmission AFT levels correct , done correctly.?
no miles on truck told, 200k 300, 500? what?
there are ON CAR tests. for all A/;T made.
we do them all. first. for sure pressure test failing, is EOL on the box. but some boxes have pressure modulator valve, that if bad. pressure are all wrong but the scans tell you it failed.
why skip OBD2 scans?????????????????????????
There are a few potential issues that could be causing your 2004 GMC Envoy SLT to go into 4-low but not 4-high or 2-wheel drive. Some possible causes include:
Transfer case issues: The transfer case is responsible for controlling the engagement of the different drive modes. If the transfer case is damaged or malfunctioning, it may not be able to engage 4-high or 2-wheel drive.
Shift motor issues: The shift motor is responsible for controlling the engagement of the transfer case. If the shift motor is damaged or malfunctioning, it may not be able to engage 4-high or 2-wheel drive.
Vacuum issues: The vacuum system is responsible for controlling the engagement of the transfer case. If there is a problem with the vacuum system, it may not be able to engage 4-high or 2-wheel drive.
Wiring issues: The wiring that controls the transfer case and shift motor can become damaged or corroded over time. This can cause the transfer case to not engage 4-high or 2-wheel drive.
Control module issues: The control module that controls the transfer case and shift motor can fail. This can cause the transfer case to not engage 4-high or 2-wheel drive.
It's best to diagnose the issue by a professional mechanic, who can perform a proper diagnosis and repair the issue. They will be able to determine the specific cause of the problem and recommend the appropriate repairs.
You have one flasher for your turn signals and one for your emergency flashers. If one turn signal works then it isn't your flasher. I would look at the connector under the bed where the trailer plug splits off. This is a common place for corrosion. With a 12v test light you can probe from the light for power. If there isn't anything at the connector at the light move up to the splitter. If you have a signal there your problem is between it and the tail light.
There could be several issues that could cause your GMC Envoy's transmission to not shift gears properly and the RPMs to rev high. Here are a few potential problems that you may want to consider:
Low transmission fluid: If the transmission fluid is low, it could cause problems with the shifting mechanism. You'll want to check the transmission fluid level and add more if needed.
Faulty shift solenoid: The shift solenoid is responsible for directing transmission fluid to the appropriate gear. If the solenoid is faulty, it could cause shifting problems.
Worn transmission bands or gears: If the transmission bands or gears are worn, it could cause the transmission to not shift properly and the RPMs to rev high.
Clogged transmission filter: A clogged transmission filter can restrict the flow of transmission fluid, causing shifting issues.
Faulty transmission control module (TCM): The TCM is responsible for controlling the transmission. If it's not functioning properly, it could cause shifting problems.
I would recommend having a mechanic diagnose and fix the problem for you. It's important to address transmission issues promptly, as they can lead to further damage if left unchecked.
you may be able to find a diagram of the air brakes on your 2000 GMC C7500 Kodiak Topkick by doing the following:
Check the owner's manual: Your owner's manual should include a diagram of the air brake system for your specific vehicle.
Search online: There are many online resources that may have a diagram of the air brake system for your vehicle. You can try searching for the make, model, and year of your vehicle along with the term "air brake diagram" to see if you can find a diagram that way.
Hook up a professional grade scan tool to the vehicles computers an check for DTC'S diagnostic trouble codes , that will tell a professional mechanic what to check.
fuses good< oops
scan the PCM see errors cranking OMG it tells you why:? sure can.
forgot the 6 new spark wire plug set, replaced 1 by one never all at once, 6 new OEM type spark plugs and gaped correctly
22 year old spark parts are no good ever.
test for spark on all 6 yet, spark is 1st or there can be no FIRE.
4.3L cranks but will not start and run and stay running.(problem1)
fire cant be seen, but spark can.
1,2,3 engine,spark, fuel good 1,2,3 in that order
spark and fuel can not run a dead engine, so 1 is first engine'
compression good 150psi up not lower, all near same
next is spark if EFI sees spark
actual fuel pressure not told just OKay. pressures matter big time in EFI, and at cranking for sure. then idle and WOT later.
engine is free running so all tests are safe, cranking too.
the service manual covers all fuel checks cranked, balance test and leak down tests.

you have a air lock...Start the car with the radiator cap off. One of the easiest ways to bleed your car's radiator is to simply remove the radiator cap and then start your engine. Leave the vehicle running until it reaches its normal operating temperature. It may take between 15 or 20 minutes before your car generates enough heat to push out the air that has been trapped in your car's cooling system. You may find that you need to add additional coolant, as air pockets can artificially inflate coolant levels.
hope this helps
