Question about 2001 Volkswagen Golf

1 Answer

Reflash the Pcm

I have taken my car to a mechanic because it would not crank. I have been given two codes. 17560 and 17978. I have been advised to find a locksmith that can re-flash the Pcm. (or ecm cant remember) I am having trouble finding a locksmith that will do this in my town. Is this something that a dealer has to do? What does re-flash mean? I own a VW 2001 Golf.

I have a 08 Milan and it drives ok then will jerk and shut down but will restart and drive off like nothing happened. I've taken it to a mechanic and was told it was the pcm, is this true?


see PCM above....what tests were done for the pcm to diagnose it. The TPS or PPS are also possible causes of your malady. (throttle position sensor and pedal position sensor.)
Don't like to second guess a man who may have had the vehicle on his OBD reader. Was the car plugged in and codes checked?
Powertrain control module

visit link above for information on the PCM...see what you think


I would ask what code the pcm had thrown up

Also...there may be a problem with the PCM on that model, there are numerous repairers around...your man may be kosher

ECM has code P0017


the cams and crank are out of time...if thats the only generic DTC you pulled out of the computer. the cam and cranks are out of sync for whatever reason. could be a faulty timing chain tensioner let one of the cams or crank jump one tooth retarded. that is if the only trouble code p0017 is present. if there are more codes present than that, contact your local factory dealer. there may be a recall on the PCM programming. when they put in the updated parameters they call it a reflash.

Diagnois pcm failure


Mechanic would have checked for good input of crank and camshaft sensors and good output of spark and fuel injectors. If they saw good input but no output, that would be a sign of a fried PCM

P0337 code


Diagnostic Test Code (DTC) P0337 is not a valid code for a 2002 Mitzubishi Lancer. However, if you are using a generic OBD code reader to get this code, there may be another "vehicle specific" crankshaft position sensor code that the code reader does not have a definition for and is rendering it as a P0337.

The generic definition for this DTC is "Crankshaft Position Sensor [A] circuit low input". This can be caused by a defective crank sensor, loose or corroded electrical connectors between the crank sensor and the PCM, defective PCM, or mechanical problems that can cause erratic crank sensor signals like timing component problems or bad crankshaft main bearings.

In your case, I would think that the noise is causing the crank sensor code. The crank sensor code is not causing the noise. There may be loose timing components that are hitting the crank sensor or something to that effect.

Whats with this P0601 code on 2001 Dodge Caravan? Many OEM repalcements (with reflash) have reocurring codes. Some forums responsd and say its some wiring, some say the battery, and some say bad...


With a P0601 OBD-II trouble code, the most common fix is to replace and reprogram the PCM. In a few cases the dealer may be able to reflash the PCM and get it working. But more than likely the PCM will need to be replaced and reprogrammed (we recommend you take it to a dealership for this). The good news is it *may* be covered under your emmissions warranty. So even if you're out of bumper-to-bumper warranty or powertrain warranty, check your warranty guide or dealer to see if this is covered.

Other people have reported that they cleared the code only for it to return again and again. Keep in mind that most shops can replace the PCM but not all can program it.

I have found out the problem with my 2007 Grand Caravan is a P0480 code, it mentions a PCM and a PCM reflash, what does this mean?


a PCM reflash is a reprogramming of your engine computer (power control module), this can be done at a dealer generally, although performance cars go to races shops
