I hear a relay click and I hear a squeek under the truck, but nothing. And last is to check the fuel pump relay as well. This scanner only works on most domestic vehicles and a few import cars from 1996 model year and up. Is there a perceptible drop in voltage output when the starter is engaged? If it doesn't it is a front axle engagement problem. Drive Train Axles Bearings problem 2005 Ford F150 V8 Four Wheel Drive Automatic My 4 wheel drive will not engage. Hello It seems as if I have the same type of problem. I know this is an old post, but I'm experiencing the exact samething.
Consumer continued home, parked the vehicle. If it's auto four wheel drive, a output shaft speed sensor that's out could cause it to believe one axle isn't moving and automatically lock into and keep it in four wheel low. Not sure where to go from here. Then I'd yank the speed control servo and visually inspect it. I had no way of knowing you'd know what you're talking about. This is the power to the Transfer Case shift relay, which powers the Shift motor in the Transfer case and power to the magnetic clutch coil via the transfer case relay.
Could they have done something then? But I hit the back of the transfer case and nothing happend. The switch looks like it has a resistor between each contact so the readings are not a direct short. I heard a noise a few weeks ago, but I was unable to determine the source of the noise. Not sure what this means. As the wheel rotates the teeth pass the magnetic wheel speed sensor and provides a reading that is translated into miles per hour. But I hit the back of the transfer case and nothing happend. The light being on is highly suspect along with no 4x4 engagement.
If not have person in vehicle hit the brakes put in park and turn vehicle off, Then with a vacuum gauge attach it to the actuator and apply 10 - 12 psi of vacuum. This extends the down time of the fleet vehicles, but assures efficient use of tax payer funds. You do this by pushing it inward, and seeing if the problem is solved. Steve Check the transfer case motor. Professional grade brake scan tools remain expensive and this made it difficult for do-it-yourself mechanics to diagnose and repair system failures. Sometimes I can turn it on and it works fine, other times it won't turn on at all. Make sure you check the vehicle coverage list provided.
First I'd verify the brake fluid level is at the proper amount, anything over, and this could trigger your problem, as well as under. Went to another Ford dealer directly afterwards, fearing the last parts guys didnt know what he was talking about, and unfortunately got the same exact answer. Again thanks to anyone that post or reads the post. But it was remembered well since it actually caused fires. I have a 1999 ford f250.
Posted on Sep 03, 2008 Just as a precaution, please check the brake fluid reservoir on that model. Not sure where to go from here. Make sure the hose isn't cracked or broken. Just trying to find out where to start. I hope this helps and you get going again.
Did find one on the net tho if need be 4x4 problems Sooo recently I got an 02 Sport trac handed down to me. I have measured the resistance of the switch in both 4 hi and 4 lo positions. Both seem to be fine. Or is it a manual transfer case? I really don't wanna have to take it in. Metal chips build up on the magnet or heavy particles become suspended in the fluid. Key to run position do not start , engage 4x4 and try to turn the front drive shaft. This reluctor ring looks like a gear with teeth on it.
This will slide into the cylinder and the other end to what is left on the harness. I don't hear a click when I turn the switch but on start-up the 4x4 lights flash on. I had no way of knowing you'd know what you're talking about. Jun 07, 2011 The sound is not coming from the glove compartment, it is coming from the panel behind the drivers seat, that's where the relays and computer are located. If you are technically adept -- you can remove the small side panel from behind the drivers seat and remove the control board. If it turns it is a problem with the transfer case.
Anyway, The battery cable was the only success we had in getting it out of low range. I have measured the resistance of the switch in both 4 hi and 4 lo positions. Wheel speed sensor codes are definitely the most common failures in these systems. The switch looks like it has a resistor between each contact so the readings are not a direct short. I don't know if this is related to your problem. Dealer admitted they heard a noise.
Of course, there's also the possibility the module went stupid on you and doesn't recognize wrong when it sees it. Keep in mind that I never used my cruise control, so I had no problems. A slack issue with the servo cable, there is an adjustment clip just before the plastic cover dead center to the engine. After some panicking last weekend it wound up being the Transfer Case Switch Motor which is located on the transfer case it self. If not the connections or the motor may be bad. It could be slipping, or the motor could be failing for the same reason my own croaked.
