Santa FE SM (2001-06) :: 2002 V6 AWD Check Engine Light Stays On After Replacing ECM

My 2002 Hyundai Santa Fe 2.7L V6 AWD failed to start a week ago. After towing to my neighborhood repair shop, it was diagnosed as a faulty ECM based on code P560 (System Voltage Problem). They replaced the ECM (along with relay) with a used one with the exact same part#. After that, the car was started and run OK but Check Engine Light stays on all the time. The codes displayed are:

P1529 TCU MIL Request Signal
P0501 VSS Range Performance

I was told that this is caused by the fact that each ECM is VIN/PIN locked. The replacing ECM was used in another car before and was locked with a different VIN thus cannot communicate with some components of the current car.

My questions are:

Can this used ECM be unlocked and relocked with a new VIN/PIN? If so, does it require the previous VIN/PIN to unlock? Most likely the previous VIN/PIN is no longer available.

Does this service require the presence of the car or can it be done with the ECM alone? Do keys need to be re-registered? The car starts fine currently.

Yukon :: 2007 - Check Engine Light Just Popped Up / Code P0455

Now, I just bought a 07 Yukon which seems to be in a great condition. The check engine light just popped up so I went to a mechanic and he said the code is p0455.

He did a smoke test and showed me that smoke is coming out of the rear of the vehicle at the gas tank area and the car needs the vent valve solenoid changed, but it's only sold at dealer.

So u went to dealer and got this part and decided to change it myself which was quite easy and fun.

I went back to clear the light, then a week later the light came back on, so I went back to him thinking maybe I didn't do it right, so he did another smoke test and sure enough we see smoke coming out of the rear again, so I looked under the car and saw it was coming out of the end of the vent valve assembly which I think is a small air filter. Is that normal? Or is the part defective?

Camry :: 2002 - Traction Control Off Light Stays On

Son was driving his car today and the roads were patchy ice leaving the addition. As he went around a turn the car started to slip and traction control kicked in. Right after that the trac off light came on and won't go off. Tried recycling the trac switch on and off to no avail. Tried to check the fuse but can't find where it is located.

Elantra XD (2001-06) :: 2002 - Red Interior Door Light Stays On

I noticed this morning that since last night the passengers side red interior door light stays on after the door is shut. The dome light shuts off once the door is closed however the red light does not. I've checked all four door light sensors that actuates the interior lighting but they all function correctly without any resistance or stickiness. The drivers side red interior light functions as it should but the passengers side stays on all the time.

I'm worried the battery will be drained if the light continues to stay on. I'd light to figure out why this is happening. If I choose to remove the bulb will there will be a draw on the battery? And do I have to remove the entire door panel in order to remove the bulb?

Chevrolet - S-10 :: 2001 - Check Gauges Light Stays On And Oil Pressure Gauge Stays At 0

I have a 2001 Chevy S10 4.3L. The CHECK GAUGES light stays on, and the oil pressure gauge stays at 0. The oil is full, and the engine runs and sounds fine. I drove it about 5 miles with no change. Up until now, the gauge has worked normally. Could it be the sending unit?

Gmc - Yukon :: 2002 - Cutting Off At High Speeds

Have a 2002 Yukon 5.3 ltr engine (155K miles) that likes to cut off at highway speeds. Usually happens after 4 or 5 hours of running at 70 to 80 mph. Strangely if I set the cruise control and do the same speeds, nothing... When it happens I end up coasting to the side at the roadway and sitting there for 15 or 20 minutes and it'll start right up and usually go the rest of the way. I've talked to a couple repair shops and they have checked service bulletins and have never been able to find anything. Will be driving to Connecticut for the 4th and not looking forward to being on 95 with the possibility of this happening again.

Yukon :: Whining Sound From Front End On 2002 Denali

I recently purchased a 2002 Yukon Denali. I've noticed a whining sound from the front end when I'm at a steady speed. When I take my foot off the pedal, the sound stops. I had it in the dealership and they first thought it was the front drive shaft and replaced it. That didn't work at all, so they then told me it was due to the all wheel drive. What is causing this?

Volvo - 940 :: Engine And Service Light Stays On

My engine and service light stays on all while I'm driving from start to end. It is a 1993 940 with about 163,000 miles on it. My mechanic who I've used for about 7 yrs is a specialist for years in only Volvo's and says it's not repairable. I't been over 3 weeks since I've been to my mechanic however, I have been driving the car only about 1 mile (about 4 times a week) just to do my errands. How long do you think I should drive this vehicle without it breaking down?

Toyota - Avalon :: Check Engine Light Stays On

The "Check Engine Light" is on. When I brought it in for the annual inspection (NY), the diagnosis was "lean fuel mixture". The fuel filter was replaced (the car has over 110,000 miles on it), and some adjustments were made in the computer, or the sensors (I don't remember which). It was found that one adjustment was effective at low speeds, and the other one was necessary for 2000 RPM. A valve cover gasket was replaced because of an oil leak, but I don't see how this could have contributed to the problem. I drove it for about 10 miles and the light went on again. What the cause might be?

Yukon :: 2002 XL Denali 1500 - Spare Tire Carrier Replacement

I have an '02 XL Denali 1500. The spare tire carrier was broken (cable had snapped) prior to me buying it. As best I can find, the part number for it is: 15026912. I'm curious if any of the newer designs (such as part# 25974845) would fit. 2 reasons I'm asking,

1) the newer ones supposedly keep the tire from falling on the road if the cable were to break, and
2) they're cheaper than the original part number.

Living where road salt snacks on vehicles for 6 or 7 months out of the year has yielded no luck in finding a functional one by checking with the local salvage yards.

Right now the spare sits in the back, which is fine most of the time, but it takes up a good amount of space when packing for trips.
