YOU CAN INSTALL PCM YOUR SELF BUT YOU DONT HAVE THE DIAGNOSTIC EQUIPMENT TO REPROGRAM IT.YOU HAVE TO REPROGRAM CRANKSHAFT SENSOR AND THEFT SECURITY SYSTEM.IF NOT THE CAR WONT START.

You can if you buy it pre-flashed. It must have the software for your car flashed into the memory.

Where is the transmission ECM on the 2002 Nissan E25


The dealership told me I needed to replace my TCM, so i went ahead and bought a remanufactured one at Auto Zone. Not being too mechanically inclined, Im still wondering if anyone has had any experience pulling one of these out and switching in a new one. I have asked this before but figured my old thread threw people off with title being about the codes instead of a potential resolution. I know Kevq35 wont like this new thread too much(thanks for the only input so far), but I'm just hoping anyone with any advice will throw it out there real quick so I know what I'm getting myself into.

I have a 2002 non turbo PT Cruiser with new zero miles engine installed. Engine will not run as computer is locked in Theft Mode. We never had an alarm system installed but I'm told the car is wired and...


The ECU is not reading the chip in the key. Replacing the ECU will not solve the problem. It is an input issue(signal to ECU) not an output issue ( signal from ECU). Perform an OBDII scan of stored fault history. Probably an ignition switch problem.

New ECM install


yes. you can disconnect either the neg or pos cable from the battery. failure to do so can result in a surge hitting the ECM...and frying it. as a rule of thumb...anytime you work on anything under the hood,except for oil canges...disconnect the battery. safety is first!!!

Where is the PCM located on a 1991 Oldsmobile 98 Regency elite?


The PCMor powertrain control module is only on 1996 and newer cars.Earlier models have a ECM or electronic control module/pcm.You want to change the ECM if its a 1992.Its located under the right hand side of the instrument panel.The ecm has a prom( programmable read only memory)in it.You will need to remove this from the old ecm and install in the new ecm.The ECM/PCM can be used in many different GM vehicles but the prom is very specific and must be used only in the vehicle it was designed.The prom will not come with the new ecm and must be carefully removed and installed on the new ecm.There also is a CALPAK in the ECM ( A devise for fuel delivery) This may come with the new ECM But make sure all parts are the same.You should get a vehicle repair manual to do this job correctly,and make sure you do not damage your PROM.Your PROM is very IMPORTANT!

Troubleshooting code PO753 ECM or PCM.


It is more likely the solenoid, the PCM is very seldom the problem, about 3% of the time to be exact.
