VZ V6 ECU/BCM/PIM Replacements First off! My sole goal here is to provide affordable reset second hand ECU's ready to be linked in car or the full security set to be purchased for a simple and easy plug-n-play solution!. VZ V6 ECU/BCM/PIM Second hand Kits Available I have begun collecting VZ V6 ECU's along with matching PIM and BCM's including a coded Key. These security components can be purchased separately or in a plug-n-play security linked kit. Below is a couple pictures of these security sets. Pricing is as follows: Linked ECU,PIM and PIM+Key with new case and blank insert - BCM + Key with new case and blank insert - Reset PIM - Reset ECU - *Resetting PIM/ECU mail service - Whats wrong with the VZ V6 ECU/BCM/PIM's? Our Holden VZ V6 Commodores are notorious for the ECU to become faulty or completely fail! The BCM is also prone to failing relays, and the PIM can become corrupt also! Here in Perth WA, I get a phone call every second day about failing VZ ECU's or see a new posting on Gumtree/forums in regards to a VZ V6 ECU having issues, or they have the typical symptoms that indicate its going to fail soon! There are 100's, and 100's of threads about the VZ V6 ECU becoming faulty and failing. Its unfortunately a VERY common issue which I think most V6 VZ's seem to get stung by at some point! The NEXT most irritating and frustrating part, is there is absolutely ZERO useful information on the web in regards to this! There is alot of mystery with changing ECU's, but I want to put a stop to that, and will be putting up a "How To" document soon! (Link to go here when completed!). With so much useless information (And myths!) floating about,everyone gets stuck with forking out 1.1K to Holden for a new ECU, which is VERY expensive for our dear old VZ V6 Commodores!. Why do the VZ V6 ECU/BCM/PIM fail? Normally, and most commonly it is the VZ V6 ECU that dies. When I have the ECU powered up on bench, it gets quite warm.. even hot after a while. So now imagine what happens when its bolted to the front of the engine exposed to the heat and weather! Its essentially a disaster waiting to happen! Ontop of that, I beleive the VZ V6 ECU plug is not 100% water proof, and seems that moisture due to wet roads or engine bay cleaning can lead to electrical shorts in the ECU causing failure. Both BCM and PIM are unfortunately completely random. And can make it very hard to diagnose the issue as they cause major havoc with the whole system when they begin to fail!. What are the common symptons/problems of a failing VZ V6 ECU/BCM/PIM? For the VZ V6 ECU, the following are a common indiction: -EXTREMELY rough idle, and struggles to run. Some injectors are not working (ECU pins have failed) -Powertrain Error and fuel gauge error on instrument cluster screen -Above errors and car fails to start, or starts intermittently -Service Vehicle Soon (SVS) error (Early sign, may not be related though) For the BCM, the following are a common indication: -Keys do not unlock doors, or are intermittent -Indicators get stuck (Relays in BCM failing) -No communication from BCM on ALDL communication line. For the PIM, the following are a common indication: -CAN Bus fault from BCM or ECU indicating the "gateway" device is not detected. -Temperature gauge not working with ignition on (Regardless if car turns over) If anyone else has more common symptoms, let me know! These are just some of the ones I look out for. How to replace a ECU/BCM/PIM I will link to a "how-to" guide once its made directly here: (Link to guide) Overall the ECU, BCM and PIM need to all be security linked together in order for the car to start. The are the security protection of your vehicle to prevent theft! When replacing the ECU or PIM, the second hand ECU/PIM that is to be put into your car MUST be reset. If the security is not reset in the device, then you cannot link it to your car. Resetting these devices is no easy task, without the correct key, its nearly impossible to do as each incorrect entry causing a longer "timeout" delay before the next entry can be done (Up to 24hours). This is why I am supply reset ECU's/PIM's ready for fitment and linking! Have a question?! If you have a questions about any of this, please feel free ask away!
