| Answer to: Computer not communicating | 18Relevance | 3 years ago | Chuck Tobias | Submit Your Question HERE | |
| Make sure that both signal and power grounds on the OBD2 diag connector are good (pins 4&5), and +12V power (pin 16). If that's not the problem check the signal wiring. | |||||

| 2010 F150 CAN Bus issues | 18Relevance | 1 year ago | hunterjr81 | Submit Your Question HERE | |
| Hello, I have a 2010 F150 crew cab 4x4 with the 3V 5.4 in it. This one has the luxury FX4 package in it also. I’m running into CAN issues. When I turn the key on, all the lights light up like normal and garages do there usual sweep motion but the passive anti theft system light beeps and rapidly flashes at me. Basically telling me it’s not recognizing the key and will not let the truck turn over at all. Initial code was a U0100 from my basic scan tool showing lost communication with ecm/pcm A. The truck was taken to a local mechanic who said it needed a new pcm. So, a new pcm was installed and 2 new keys programmed. However I am still having the same issue and the mechanic gave up and couldn’t figure it out. I bought a breakout box and plugged it into the OBD2 port to test the network. I am reading 120 ohms of resistance across pins 14 and 6 when it should read 60. I bought another scan tool that had more capabilities and scanned it again. It’s reading faults everywhere across multiple modules and I can’t communicate with the PCM. I bought a used instrument cluster thinking maybe the cluster was bad but the issue didn’t change. The last test I ran today was testing resistance between pin 6 of the OBD2 port with pin 59 of the PCM connector harness side and got less than 5 ohms of resistance which is good. I then tested resistance between pin 14 of the OBD2 port with pin 43 of the pcm connector harness side and couldn’t get a reading so it was open. I ran that test based on recommendations from the workshop manual I have for the truck. I do have a full wiring diagram as well but it is a bit intimidating. i have done a visual inspection of all the wiring I can see and don’t see an issue yet. Anyone have any idea on what my next step should be? | |||||
| Answer to: CEL came back | 18Relevance | 3 years ago | Dan | Submit Your Question HERE | |
| CEL came back The Check Engine Light (CEL) means that an Electronic Control Unit (ECU) found that a parameter is out of bounds by a very significant margin, The ECU that reads the parameter, has sent a request to the Engine Control Module (ECM) to illuminate the Check Engine Light (CEL). Using the On-Board Diagnostics port (OBD2) and a compatible Scan Tool, you can retentive Diagnostic Trouble Codes (DTCs), And then, using those Trouble Codes, we will be able to try and pin point your issue. I just don't know how serious the problem (...) is Saying "the engine signal light on" does not give us the required information to tell you the nature of the issue, We need to know the Diagnostic Trouble Codes to know the severity of the issue. To get the codes, either purchase a simple OBD2 scan tool, or go to a parts store that offers free OBD2 scans. Then post the trouble code on the forum, and consider tagging specific people you may want to see your update on the topic using the @ feature. Also if possible post what was the repair performed previously, what parts and their manufacturer (OEM/ DENSO / Non-OEM) | |||||
| RE: Misfires on 2012 Honda Civic | 18Relevance | 4 years ago | CrashxZ | Submit Your Question HERE | |
| Thanks. From the above page - I have isolated the spark plugs and the ignition coil out from the equation. There was no fuel on the old spark plus when I changed it, the ignition coils had some marks of wear (probably because of the 194k miles) - but they worked fine. I changed them because I got a good deal. I have checked the air filter and it was fine, changed it 1k miles ago. This is the stuff I could do myself. For checking compression, I don't have the tools and I'm quite scared to do it, the same goes for the vacuum test. I have visually inspected the lines though. They look old, but I don't see any cracks or leaks(at least visually). Can we make a more targeted diagnosis using the OBD2 data, if yes, what am I looking for? I would attach the OBD2 Scan data, but the anyscan a30 mobile app doesn't allow to export the recorded data. ALso, I think the misfires occur when the engine is decelerating from a high rpm. I might be wrong and this might simply be due to the delay between the phone and the obd 2 scanner. It would really help if someone could tell me what exactly am I looking for in the OBD2 data. | |||||
| Scan tool for 1995 Mercury Cougar? | 18Relevance | 4 years ago | CraigInAlexandriaLA | Submit Your Question HERE | |
| Hey Scotty, I'd like to buy an OBD2 Scanner/Reader from your Amazon store, but I'd like your recommendation for a good one to test things like the Cruise Control system, its steering wheel buttons and components. I'd also like to disable the Airbag system because you say it's not worth fixing on older cars, or at least prevent the dash error code light from flashing without removing the bulb(s). One that will let me reset/erase all codes. I have a 1995 Mercury Cougar 4.6L V8 XR7/SE that's running very well otherwise. The Ford dealership told me that the Techs would use an OBD2 to test the Cruise Control, but they don't work on anything this old anymore. I'd like to have an OBD2 that can do some advanced stuff, but I shouldn't need your top of the line ones. I bought a used set of OEM 1995 Thunderbird/Cougar-XR7 Service Manual and the Electrical and Vacuum Troubleshooting Manual so, with a slightly more than adequate ODB2 for these tasks, I should be set. Thanks in advance, Craig | |||||

| It just gets better gas mileage and where is the engine out and a transmission less. Most of them are automatic and they just come on and off depending if you're driving slower or faster. But some you can switch modes. If you have a switch that turns you can put on Eco normal sport. Some are set up that way some aren't | |||||
| Answer to: 2014 ram dodge eco diesel | 18Relevance | 3 years ago | Dad2LM2 | Submit Your Question HERE | |
| Do not, not not! buy a high mile Eco diesel. When they go bad, they can get real expensive real quick. If you want a RAM from that generation, get the 5.7 hemi. Way more reliable, and the difference in repair cost will more than offset the fuel cost. | |||||
| Lexus eco heat/cool | 18Relevance | 3 years ago | hif1980 | Submit Your Question HERE | |
| Hello Scotty! I have 2022 Lexus ES350 with around 9000 miles. Since I got it about a year ago, I’ve been using it with the Eco heat/cool on. Will this mode affect the longevity of the air compressor? Should I turn it off? I honestly don’t see the point of keeping it on but I will if it helps the engine to be less stressed. Please let me know what would you do. Thank you! | |||||
| 2000 Mercedes W163 parasitic battery drain | 18Relevance | 5 years ago | Belve510 | Submit Your Question HERE | |
| Ok so let me be as informative as possible in my situation. I have a 2000 Mercedes ML320. My issue lately is that I have a parasitic battery drain. I tested every fuse with my multimeter and I finally found where the drain was coming from and it was fuse #13 (Diagnostics/ steering angle sensor) which was located under the engine hood. This checks out because I tried to connect my OBD2 scanner and it powers on but won’t establish a link with the DLC. Also I took the car to get a smog check and it fails due to not being able to connect to the OBD2. note that I’ve changed all battery related components in the car such as battery, alternator, starter, spark plugs, coils, and wires and the car still dies after it sits for 2 days. Now I’m stuck and don’t know what to do or what to fix. I need advice on what to do next. I want to save money and not have to spend a fortune at the dealership on a car that’s 21 years old now. Like what would cause the car to drain? Do I need to change out the OBD2 port? Please help. | |||||
| 1994 Buick Century 3.1 V6 special - Stalls out most times on first start. | 18Relevance | 5 years ago | babyjones | Submit Your Question HERE | |
| Hello to you all, My first visit. I think the car is attempting to set the idle? I don't really know what's going on. It will start and run a couple mins. The idle goes up and down for 3 or 4 cycles, so low that the car stalls. If I put just a touch of pressure on the gas I can catch it before it stalls. It will eventually run smooth and idle fine for the rest of the day and on every subsequent start up after throughout the day. I almost think it's suffocating itself. I am not a mechanic, but I want to learn. A secondary note. I understand before OBD2 came online officially all kinds of connectors where being put on cars for diagnostics. Auto zone said it could not scan for codes because the car is a 1994. I've been under the dash a bit lately and it sure looks like an OBD2 connector mounted there. Could my 1994 century have gotten an early OBD2 connector? I mean it is the "Special Edition" after all. LOL! Many Thanks, I look forward to hearing from you. | |||||
| Answer to: GM's Eco Tech 1.5 L 3cylinder turbo | 18Relevance | 2 years ago | Chuck Tobias | Submit Your Question HERE | |
| Scotty has mentioned in his videos that both the Ford and GM 3-cylinder turbocharged engines are garbage. Aluminum pistons became popular in the 1920s due to their low reciprocating mass and have been the norm for quite a few decades. As far as I know the last automotive engine in the U.S. to use iron pistons was the Chevrolet "Stovebolt Six" (aka "The Cast Iron Wonder") introduced in 1929, where iron pistons were used to reduce cost ("a six for the price of a four"). That engine used cast iron pistons into the early 1950s. | |||||
