Circuit boards had specific roles like regulating fuel injection systems. By the s, on-board computers became more sophisticated. They could now control most of the electrical processes of the car, including climate controls, braking systems, and odometer.
Today, vehicles are really like computers with wheels. Cars are upgradeable and customizable, giving the backyard mechanic incredible control over performance.
How Do I Reflash My Dodge PCM? (Updated)
Modern vehicles have a set of computers commonly referred to as modules that communicate with sensors throughout the car. Manufacturers started phasing in CANs in the early s. The powertrain control module PCM is one of the most important computers in your car, usually managing the engine and transmission, depending on the make of your vehicle. Then, the computer can adjust the ignition and fuel injection timing and the position of the camshafts and throttle.
The TCM uses incoming sensor data to determine when the transmission needs to shift. TCM functionality has improved over the years, adding input from cruise control, throttle and traction control system.
This reduces gear hunting and wheel spin. By combining them, the PCM can better regulate their functions together. For example, when the PCM changes gears, it can pull back the throttle to shift smoother. However, the two units operate independently. You can program one system without affecting the other. To confuse things a bit more, the term electronic control unit ECU is often used as a generic term for any built-in system that controls multiple electrical features in a car. The PCM senses and monitors more than factors in a car or truck.
Here are a few of the most essential processes.
How to Reset the Computer in a Jeep Cherokee
Once warmed up, the PCM adjusts the ratio to decrease the fuel being pumped in. Ignition Timing — Depending on different conditions, the PCM can make the spark plugs fire in a faster or slower sequence, helping the engine deliver an optimum amount of power per RPM. A qualified mechanic can understand this error code and make the necessary repairs.
Powertrain Control Module reflashing is essentially a software upgrade. PCMs are built with microchips that can be reprogrammed electronically without being removed from the vehicle. This process has many names. Auto Manufacturers are continually updating controller software to solve problems such as false diagnostic trouble codes, hesitation, rough idle, emissions problems, hard starting, poor fuel economy and other issues.
You may want to consider reflashing after installing an aftermarket performance cam, bigger cylinder heads, a different intake manifold or fuel induction system to compensate for changes in airflow.
A professional tune is highly recommended when used in conjunction with other aftermarket parts. The PCM might be unable to read its sensors and cannot adjust properly.
Virtually all and newer Domestic, Asian and European vehicles are compatible with the J compliant pass-thru tool. Reflashing can also be accomplished using professional grade scan toolswhich include the same functionality, plus many other features unrelated to reflashing.The Truth about Engine ECU Upgrades, Chips & Re-mapping - Auto Expert John Cadogan - Australia
These are even more expensive. In addition to the J pass-thru device or professional scan tool, reflashing requires:. Subscription fees vary by manufacturer. They have several payment options: per-vehicle, 24 hours, 72 hours, weekly, monthly, or annually.Flashing your car's computer, or ECU, will open up many performance gains that are often restricted at the factory for various reasons.

This procedure first came to me from the folks at Avenger. I then verified it with a phone call to a Chrysler Engineer who had called me a year or so ago to ask about my experiences with a certain part on my TJ.
I figured he owned me a favor. He had to check up on this for me. He called me back a week later and did indeed verify this procedure and what it does. After performing this procedure the PCM will re-learn and store into Adaptive Memory your engines performance characteristics. Please perform these steps exactly as they are written, in the order they are written. When you start the engine it will be running off a set of pre-programmed tables that come with the PCM from the factory.
Warm-up Cycle A warm-up cycle happens when all of the following conditions exist. Once your engine has gone through 50 warm-up cycles in at least a mile distance the PCM adaptive memory is set.

I recommend the Factory Tools if you are doing much programming, they are very easy to program with. I followed this process on a Dodge SX 2. I find that my customers are usually trying to install used ECMs instead of new and I want things to go smoothly for my part. Anything else?
Diagnostic Tool s : Modis I knew I couldn't be the only one that found that post intriguing! I cant wait to try it.
Also, does anyone know where to navigate to see what Chrysler modules are programable and what the latest calibration is for a particular module before you pay for a scrip? Nice work Mr Thats the page i was looking for! Did they move this? Could they make it any harder to locate? I used to be able to get here months ago, when i last checked, before i was a programming effecienado.
Thanks again Kai, you just may be Flash Gordon! I've done this on a few before and all that was needed was clear the vin, rewrite the vin, rewrite mileage. I'm not sure if i was doing something wrong or maybe the tool wasn't doing it right but it took several attempts and finally went through. Used Pcm. Any experience with replacing pcm with a used pcm. Dodge is out of stock on PCM for 03 Intrepid. I got PCM with identical part number and calibration.
The key does not have a transponder. I used Tool box 2 to reset and vin write process. Now the car does not turn over and I cannot get any codes with modis. One problem I had was when doing the calibration update, it did not finish updating the TCM.

Last Jump to page: Results 1 to 10 of Thread Tools Show Printable Version. The past few days the JK has been acting really funny.
It started out on Tuesday when I was driving. All of a sudden, the engine started to spit, its almost died and then the speedo and tach started going crazy followed by almost every light in the cluster going on and off. Friday my daughter drove it to school and it wouldn't start afterwords. I ran down later that night and it started right up.
I let it run and it acted fine. It wouldn't start up. It had power but wouldn't even turn over. At first I thought the starter was gone. I let it sit for a minute and tried again. It started but wouldn't rev no matter how much I pushed on the gas. I put it in drive to get out of the middle of the intersection but it was just a crawl. It would go faster in reverse, so I backed into a parking space.
The only thing I could think of was to run the codes.

I didn't have my tuner so I just pulled the battery cables off and let it sit for a few minutes. I hooked them back up and it started right up and would rev. I decided to make a run for it and made it home. Then there are the next two that lead me to believe I have a PCM issue. I have done a few searches and everything keeps pointing to the PCM. I disconnected the battery today and let it sit for an hour or so.
I disconnected the connectors to the PCM and then hooked things back up. The engine light is still on. I have cleared the codes and disconnected the battery again.
