Which happens that the DME or ECU unit got wet. But I did not know until I tried to started but. Here is how to reset your cars ECU to get better fuel economy andor for your car to lean how to use new upgrades. View the full threeday conference programme for the free Open Technology Forum held alongside the Automotive Testing Expo Europe exhibition, with full details about. You can also make optimized performance changes by editing, tuning and reprogramming cars ECU chip data brain that controls how the car runs. This is typically. From the first telephone contact with ECU Testing to the return of the repaired ECU the service was top class. Your communication keeping me advised by emailmessage.

But they didnt. The choice probably had more to do with production scheduling and new model introductions than profile or image. GM knew OBD II was coming and that it would require a new generation of PCMs that were faster, more capable and able to be programmed electronically. Up to this point, Program Read Only Memory PROM chips held all of the PCMs vital calibration information and operating instructions. GM pioneered the replaceable PROM chip as a way of programming a limited number of basic PCMs to fit a wide range of GM makes and models. A replaceable PROM chip also meant the PCM could be retuned if necessary to correct certain kinds of emission or driveability problems. It also meant that if a bug was later discovered in the original factory programming, it could be corrected in the field by simply replacing the original PROM with an updated corrected PROM a tactic GM has successfully used over the years to fix many factory flaws. Performance enthusiasts also liked replaceable PROMs because the chip could be replaced with one that provided more spark advance, fuel enrichment, a higher rev limit, etc., to squeeze more power out of the engine. But replaceable PROMS had a serious drawback there were too many of them Every model year and every running change meant another PROM had to be created. Every field fix or recall for an emissions or driveability problem created more part numbers to keep track of. Api 2000 Venting Calculation Software'>Api 2000 Venting Calculation Software. Were talking thousands of different PROMS. The General Motors PROM Identification manual that OTC used to provide with their Monitor scan tool and Pathfinder software contained over 3. GM PROM numbers Enter the flash reprogrammable EEPROM Electronically Erasable Program Read Only Memory chip. PCMs built with EEPROM chips can be reprogrammed in a matter of minutes without having to remove the PCM or replace a single chip. Its all done digitally with the proper access codes and input data. Following the Geo Storm, GM began phasing in PCMs with flash reprogrammable chips in a variety of cars and trucks. By. 1. 99. 5, most GM models had the flash reprogrammable PCMs. Ford and Chrysler were also doing the same thing as OBD II arrived on all cars and light trucks in model year 1. Today, almost all PCMs have reprogramming capabilities so changes and upgrades can be made if needed. Thats over 1. 00 million vehicles that have been built since 1. WHY REPROGRAM As we said earlier, PCMs may need to be reprogrammed for several reasons. One is to fix factory bugs. Every time Windows OS or a new phone for example, comes to market, it they always turns out to have bugs and security holes that were somehow missed but must be fixed by downloading and installing the latest patch. Its a never ending cycle of upgrades and patches. Fortunately, it isnt that bad yet with automotive PCMs, but it has become a crutch for automakers who rush products to market that arent quite ready. This philosophy of build it now and fix it later creates a lot of unnecessary recalls, but at least it gives technicians a way to fix factory mistakes without having to replace any parts. A reflash may also be required if the factory settings for the OBD II self diagnostics turns out to be overly sensitive especially after a few years of operation. The same goes for driveability. What works fine in a brand new car many not work so great after. Changing the fuel enrichment curve, spark timing or some emission control function slightly may be necessary to eliminate a hesitation, spark knock or other condition that develops over time. For example, on certain GM vehicles the Check Engine light comes on and sets a code P1. EGR valve. Cleaning or replacing the EGR valve and clearing the code does not fix the vehicle because the code usually returns. The real problem is the OBD II programming in the PCM. When the PCM commands the EGR valve to open to check its operation, it isnt allowing enough time for the valve to respond. A brand new valve takes only about 5. NOX emissions failure but is long enough to trip a fault code. The fix in this instance is to reflash the PCM with new instructions that allow more time for the EGR valve to respond. War In The Pacific Tutorial Pdf. Another example are rich codes that may appear on some late model GM vehicles. The problem here is that the original OBD II self diagnostic programming doesnt allow enough leeway for changes in intake vacuum that occur as the engine ages. After. 6. 0,0. 00 miles, intake vacuum isnt as high as in a new engine which can create a rich fuel condition. The cure is to flash reprogram the PCM to compensate for the drop in vacuum. When vehicle manufacturers calibrate the onboard diagnostics to meet federal emission standards, they have to draw the line somewhere as to what operating conditions might cause emissions to exceed federal limits 1. Thats the threshold where a fault code must be set and the Check Engine light must come on. It doesnt mean emissions really are over the limit, but it is possible based on laboratory dyno testing and field experience. Depending on the application, the vehicle manufacturer may even set the limit a little lower just to be safe because the last thing any OEM wants is an expensive emissions recall. Unfortunately, vehicle manufacturers dont always tell us their diagnostic strategies or even their operating strategies for their. Some service manuals include a fair amount of system background information but others provide almost nothing beyond a basic diagnostic flow chart. Maybe the engineers who design this stuff think technicians only need flow charts and assembly instructions to fix vehicles today. But it often takes a much deeper understanding of the system operating logic to figure out whats setting a particular code especially when the cause isnt obvious. The best advice when confronted with a troublesome code that keeps coming back or seems to set for no apparent reason is to check for any Technical Service Bulletins TSBs that may have been published. Changes are it might be a programming issue that requires a reflash to fix. Something else to keep in mind with respect to all late model flash reprogrammable PCMs if you replace the PCM for any reason, the replacement unit must be reflashed before it will start the engine If the PCM is not programmed, its just a dumb box like a PC without an operating system. Some remanufacturers who supply reconditioned PCMs now flash program PCMs for specific vehicle applications. But to do this, they need three critical pieces of information the vehicle identification number VIN, the type of transmission manual or automatic and the emissions type federal certification or California. Your other option is to flash reprogram the PCM yourself. NOT JUST DEALERS ANYMOREUntil recently, car dealers were the only ones who had access to the tools and software needed to reflash PCMs. Thanks to the passing of Senate Bill 1. September 2. 00. 0, vehicles manufacturers must now make this technology available to independent repair shops at reasonable cost. Starting in 2. 00. China ECU Tools Centre.
