Question about Cars & Trucks
The car will crank but not turn over. Ran a Vag-com and it is unable to connect to ecu. Check the wiring and it look all good to ecu. We are checking relays right now but any one else experience a similar problem to guide to where to check. If I want to DIY, the autel ds708 scanner can be suitable or not ? The car die while in second gear. No shudder or anything just die. I am running the APR software the connect to the ECU is for sure not working because I can't change fuel program or anything. Any thought please let me know. Thanks!
Ran vag .com so its a VW but unsre what year and what model and what country its in ,now even euroepon models had a OBDII before 2005 for VW but it wasnt compulsory till then here ,So i suspect that you have a europeon software or asian software as a american vehicle will have by american law the same software so it can be read for the emisions test unlike in europe where a probe and a anayliser are used .Iam asuming this is a petrol passat or similar like a audi but different problems can occur to different engine and your is no doubt a bigger V6 or something which i wouldnt see very often as diesels are the mainstay here with manual boxes ,now if this is a older vehicle with a ignition module seperate a bosch unit with 7 wires to it then this i would suspect if it starts from cold and runs but under load it fails ,another problem depending on model is the coil pack with built in ignition module bolted to the fire wall these crack with heat and give a similar problem.Right i have thrown my pennysworth in but without age and model i cannot help anymore

SOURCE: Is the replacement of an ECU in a 96 sable straight forward? I just bought a 96 sable for a great price. The only thing is that it needs a new ecu. The stealership wants $800. I currently have a 96 je
1996 is the beginning of odb II when all the manufacturers had to start calling things by the same names, more or less. the ecu became the pcm, powertrain control module. physically installing a new one in your sable is about as easy as you describe. i can give you the step by step. if it really is a new one, you should not have any problems. if you use one from a junkyard it might not go so smooth. i don't know when ford started using vin matching, but it can be nasty. ok, here's the procedure i found:
1.disconnect battery negative cable
2.remove cowl deflector
3.remove engine wiring harness ground cable from the dash panel
4.remove the pcm electrical connector
5.remove the mounting nuts
6.remove the pcm
and then to reinstall
1.install the pcm in the dash panel. tighten the nuts to 71-106 in-lbs
2.install the pcm electrical connector
3.connect the engine harness ground cable
4.connect the negative battery cable
hope that helps
