obd2,ecu, diagnosis tool free downloadToyota 4Runner 2004 Alternator Issues solution
Car model and year: 04 Toyota 4Runner 4.7l
Issue: have alternator issues
Details:
I went on a business trip for a week, got back home went to crank it and the famous click click click. Battery was under warranty took it to napa they tested it said it was just low they charged it and i brought it back installed and got her running. Here is where I think I have a problem, I let it run for about 15 minutes to warm up it was rather warm here in South Carolina over the weekend. I had to go to my shed and get something so I turned it off. when I returned I cranked it back up and now when it cranks if the tack gets below 1000 rpms the engine shuts off. After a couple of times of doing this not wanting to kill the battery it still does this when cranking and giving it gas, it will run but when I take my foot off the pedal it dies.
Optional method:
Option 1:
I’d start with Foxwell BT715 battery analyzer from:
Foxwell BT715 will tell you that the alternator is “good” (or bad) and what the charging rate is, as well as if the battery is “good” (or bad).
Option 2:
If you can get the truck to most any auto part store they can test it for you for free. That way you don’t have to buy that tool unless you want to. Just get it started, and drive over to a store, keep it running and they should be able to do a load test on the battery and charging system. Its not 100 percent accurate but its pretty good.
Operability:
For the option 2 method, it was my first thought but when I go to put it into gear it shuts off…..
Option 3:
Use a meter… measure at battery while engine idles, you should have ~ 14VDC. If only 12VDC or lower, the alternator is not working properly.
Option 4:
I’m guessing it could possibly be something going on with the throttle body, in older models vehicles the TPS…Throttle Position Sensor is a separate/replaceable part attached to the throttle body and if bad can do what your’s is doing plus other issues, but on the 4th Gens 4Runners the TPS is integrated into the throttle body and can’t be replaced.
I have never had to test one but you can Google search “Symptoms of a Bad or Failing Throttle Position Sensor” , which may help you get started on how to test the sensor to see if it’s bad, you may have to do more research to be able to actually test it properly, such as the values mentioned to know if it’s within the correct range and the type of sensor it is.
Option 5:
I suspect a bad battery coupled with bad NAPA testing, it is possible. I have had batteries heat up and the plates touch. So If possible check voltage, find a ground inside the car, ground one side of the meter and CAREFULLY test the cigarette lighter voltage, I believe it is straight battery juice. Be careful not to short out the probe, protect it with tape if you have to.
Please try any of the above methods according to your actual situation.
Good luck!
Toyota 4Runner 02 ABS Bleeding by Foxwell NT630 Plus
Car model and year: Toyota 4Runner 02 Sport
Symptoms: Prolonged motor cycling-whirring sound upon startup. Squishy brake pedal and rig lurches forward when almost at a stop, while making motor cycling-whirring sounds.
What I tried to do:
Physically inspected all connection harnesses at the ABS unit as well as speed sensors at each wheel and they seem to be fine. No breaks etc.
Picked up a complete ABS/Master Cylinder unit from a local guy for $150 so why not swap it out to see if it’ll help.
While researching bleeding procedures I stumbled upon the 4th Gen site and they seem to be split into two camps: normal bleeding procedure and those saying the ABS actuators had to be tripped via some sort of Toyota software and a special connector. Apparently if you leave the ABS unit alone you can bleed old school but if you replace the ABS unit, like I’m going to do, you need the software? Others say to just drive the car hard, brake like a lunatic to trip the ABS and then bleed.
My question:
If ABS actuators are not tripped and opened, air may accumulate inside the ABS unit itself?
What is the most effective way to bleed an 02 when replacing the ABS/Master Cylinder Unit?
Suggestions:
I was checking out this scanner, not a bad price, when I noticed in the fine print that it works with Toyotas…2003 and up… search continues.
Found it! Same price as the dealer to bleed and I won’t get sucked into other “needed” repairs.
Looks good. Pages #26 & #27 of interest in the user’s manual.

Might be worth calling Foxwell tech support to see if it will hook up with an 2002 Toyota brake system. Same as 2003.
Worth the call as these will usually get a *lot* of vehicles but will skip weird ones.
Want to sure on what you exactly need for your vehicle.
I. E. Doubt it does 100% ABS function bi-directional for all the vehicles listed in the advertisement.
Will do most. That’s the problem with these lower end cost units. Truth in advertising.
Then there are other units (next price increment up) which simply clone the auto factory software and bundle it up. (software license infringement?)
This is where the fun begins.
Test reports:
Yes, Foxwell NT630 Plus has brake bleeding function for cars equipped with ABS brakes
Hope it helps.
Bleed Jeep Liberty ABS with Foxwell NT630 Elite
I emailed foxwelltool.com asking for a low priced scanner that has the ABS Bleeding feature for use on my 2002 Liberty and this is the one that I was recommended.
Customer Service was good. They had me do a Software update. And I was able to activate & Bleed the ABS system on my 2002 Liberty.
This innovative NT630 Elite ABS and Airbag Reset Tool with SAS Function does not only have extensive coverage of vehicles but also provides accurate and professional diagnosis of ABS and airbag faults.
It has an 8MB Ultra Micro SDHC card to store data & upgrade software. You’ll need an Ultra Micro SDHC card reader to connect to your laptop for software updates. It also has a USB cable to access the Ultra Micro SD card.
Pros:
*I was finally able to Bleed my ABS unit!
*Ultra Micro SDHC card for storage.
*USB connection for PC.
*8MB Ultra Micro SDHC included.
*It has a Graft feature for sensor readouts.
*Its says they support every car.
*Customer support was very prompt to help.
*Nice Low Price $120.
*Nice hard plastic carry case.
Cons:
*It didn’t have a JEEP category. I was instructed to use the CHRYSLER
category then select “2004 and below”
*It has many Chrysler features that are not part of the Jeep tests and if you
select them the unit either takes a long time to tell you its not supported or
it locks up (or I didn’t wait long enough for the message).
*Software update took about an hour.
Foxwell NT530 Review on Honda Good or Bad
Put together all Foxwell NT530 Honda Civic code reader respective test reports good and bad in this article.
- Able to do everything HDS can do. Reset DTCs and clear TPS sensor data for cleaning and changing throttle bodies, reset ECU and run tests like make the wiper squirter motor run with the sunroof open.
- I got the NT530. I was able to perform the TPS Alignment and fix my bouncing idle issue so it did what I needed to do so far. It has a good amount of functionality so all in all I’m happy with the purchase.
3.The Foxwel NT530 (with Honda software) is really a great little tool and reasonably priced.
- 4. I bought the Foxwell NT530 as suggested and it worked perfectly. It has a lot of other bidirectional features for Honda so I highly recommend it to anyone who owns a Honda and does their own work.
- 6. I bought the Foxwell NT530 and used it to clear the TPS sensor data. Took only a minute to do with the scan tool and then 5-10 minutes of idle relearn time.
When you’re all done and it’s back together reset the TPS data with a bidirectional scan tool like the Foxwell NT530 (I’m still really happy with this tool, by the way) and do the idle relearn procedure.
