need help im clueless....

[Roger_cha]

yea im clueless about what does the eng cont fuse does.... the small 10amp eng cont fuse.... it keeps on blowing out on me.... what does it means... the car runs fine but my techometer jumps when driving... and my brake light turn on... any help.... thanks.....

[onosqv]

last time i searched, that eng cont fuse has something to do w/ the egr. So probably something along the egr circuit is shorting out.

[onosqv]

o yea, and dood, search...

i actually answered this question earlier in teh year, in which i also searched and found a possible answer... :p

search -> engine control fuse -> 2nd result

[Roger_cha]

thanks for the tip ill search on that...

[Roger_cha]

o yea if u said that you search a possible answer can you tell me wats the problem... so i can make my research short... thanks

[vancouverbc]

it supplies power to aiv solenoid, egr solenoid, aac solenoid, scv solenoid and bulb check relay. ill post up a electrical schematic.

bulb check relay. sounds like it has something to do with bulb check relayand related circuit.

[vancouverbc]

bulb check relay is blue . located by fuse block per pic.

[Roger_cha]

yea i have another question the engine check light doesnt come one the brake light comes on.... but the question that i want to ask is does the fuse has something to do with my a/c compressor.... when i put the exact fuse on it blows up but when i put a higher amp fuse on it... it works fine everything is ok no problem... but my a/c compressor turned on all the time... even if i turn it off on the control... when i take the fuse off and leave it with no fuse the a/c compressor turned off and the a/c is fine. but my brake light turned on even if i check my e-brake and my brake fluid... my car has no a.b.s too...

[Roger_cha]

o yea i forgot to mention one thing... when i leave the fuse out and when you push the gas peddle you can hear a loud buzzing noise coming from under the steering wheel right on top of the brake peddle... the buzzing noise sounds like electrical are touching each other and my brake light slowly die out but when you release the gas peddle the buzzing stop and my brake light turns on agian... i want to take the car for a diagnostic but they say that it would cost about 150 cause it might be alot of things...

[vancouverbc]

i dont think there is any connection to a/c from that fuse. you have some kind of short in check bulb circuit. brake fluid level switch is part of that circuit.

[Roger_cha]

yep i check the level switch no problem... but when i press on the gas pedle there is a loud buzzing noise coming from on top of the brake pedle and the light goes out but when i release the gas pedle it stops buzzing and the brake light comes on agian...

[vancouverbc]

Relays buzz when they are not getting enough voltage. could be normal.

[Roger_cha]

thanks foe the info on the buzzing noise but in your idea wat do u think that cause the fuse to blow up like that....

[vancouverbc]

There has to be a short somewhere. that means 12v+ is touching 12v-(ground). loose wire or wire with plastic coating rubbed off.

[Roger_cha]

o yea hey i think i might figured it out.. i think that the problem might be the bulb check relay because... i check the diagram you post carefully and the diagram that i have download.. i think that the relay might be mess up... but what confuse me the most is it had nothing to do with my a/c compressor and yet my a/c compressor turned on even if i switch it off... hows that possible... i think that i have alot more problem then just the fuse or relay itself....

[Roger_cha]

o yea and i forgot to mention that my techometer jump when you get about 2000 it jump about 2500 then back down to 2000 it does that for just a quick second on every gear.... and the engine runs fine and very strong too... i even self dyno the ecu to check wats the problem the ecu shows that everything is fine... 5 long flashes and 5 short flashes....

[vancouverbc]

The fuse circuit actually does not go past the bulb check relay unless the relay is really screwed up. disconnect the bulb check relay and put new fuse in and see what happens. If it doesnt blow fuse, then you know the bulb check relay is the issue.

The aiv , egr , etc wiring and connectors might be the problem if not bulb check. An a/c wire etc obviously is being affected by this.

[Roger_cha]

ok thanks foe the tip ill check it up and try to see wats the problem with it and ill give u a holla back thanks...

[Roger_cha]

yea i want to ask something where can i get a diagram just like the one you showed me no the location but the wiring diagram..... cause when i look at the wiring diagram im a little confuse but when i looke at the ones u showed me i can understand it alittle better...

[vancouverbc]

I got mine from mitchel guide in library.

[Roger_cha]

thanks foe the info.... yesterday i check the car and it was the bulb check relay i unplug it and every thing in my car dies not the engine but the radio and all of the electronic in my car dies... but when i put the fuse back on and plug in the relay back on everything is fine now the fuse did not blow... thanks foe helping me man i apprecieated....

[vancouverbc]

If you are using the same bulb check relay, you have not found the problem. You must have inadvertently moved a wire or something. The pink and brown wires may be touching at the bulb relay. I'm not sure how common it is for a relay to short out versus the wires at the connector touching, etc..

the buzzing noise you here from under the dash is a relay or flasher or the voltage regulator on the cluster thats from not egnuff ground.

[vancouverbc]

the buzzing noise you here from under the dash is a relay or flasher or the voltage regulator on the cluster thats from not egnuff ground.

It can be a bad ground or a weak source of 12v+. The relay buzzes because it does not have enough power to fully open. Roger had the fuse out when he heard the buzz so the relay was probably getting a weak signal from the ecu that was too weak to open relay.

[Roger_cha]

thats true... the buzzing only happen when i dont have the fuse on... when i put the fuse on it stops.... o n yea after i fix the problem my engine idle very smoothe and i goten alot strong when i didnt have the fuse in. that means that the fuse is need for alot of things... well anyways thanks foe helping me solve my problems...
