It should be something you can do yourself. Most pcm's are located on the inner fender with two or four screws holding them on and two to four wire harness plugs going into them. The ECM is not the first place I would look for any problems.PCM failure is very rare.Much better chance of input power problems rather than the actual ECM itself.

How do I replace the computer chip that controls the gauges and sensors on my Buick Lacrosse?


What computer chip ? Your vehicle has up ten computers on the vehicle . PCM - engine control module , BCM - body control module , SRS - air bag control module , EBCM - electronic brake control module , The instrument cluster has a microprocessor inside , the heater / A/C control panel is a control module .All the control modules on your vehicle are connected on a serial data communication network .
There are 2 different communication networks on this vehicle: The class 2 network and the GMLAN network. The class 2 serial data circuit is the low speed link, and the GMLAN serial data circuit is the high speed link. Modules that need real time communications are attached to the high speed network. The engine control module (ECM) is the gateway between the networks. The purpose of the gateway is to transfer information from one network to another.
When one of these modules is changed it needs to be programmed , unfortunately the dealer is the only place to have it done at. A GM factory scan tool is needed to do the job ! If it's not done correctly the whole vehicle network will lock up, making the vehicle inoperable .
Class 2 Serial Data Link
The class 2 serial data link allows the following modules to communicate and share data with each other:
?€¢
Body control module (BCM)


?€¢
Digital radio receiver


?€¢
Electronic brake control module (EBCM)


?€¢
Engine Control Module (ECM) (LY7)


?€¢
Instrument panel cluster (IPC)


?€¢
HVAC module


?€¢
Powertrain control module (PCM) (L26)


?€¢
Radio


?€¢
Inflatable restraint sensing and diagnostic module (SDM)


?€¢
Vehicle control interface module (VCIM)


The GMLAN serial data communications circuit used on this vehicle is in a linear topology. The following modules are connected to the link, in order from DLC to the end of the linear configuration:
The following modules communicate on the GMLAN serial data circuit:
?€¢
The transmission control module (TCM), (LY7) 3.6-L


?€¢
The engine control module (ECM), (LY7) 3.6-L


I very strongly suggest you don't try to fix this problem !

How to replace a ecm


It should be on the drivers side firewall, are you sure you don't have a loose connection somewhere? Reason I'm asking is that ECM'S rarely go bad and if they do they don't just start working again.

I have a 04 dodge Durango hemi 5.7. Error code p0648- p2122- p2127- p2138. Car is idling at 10mpg. The dealer replaced the throttle body and recommended I pay them $900 bucks to replace the PCM, I replaced...


-Need to determine what these codes are before replacing parts.
-After replace, The CODE NEED to be Erase.
-Find these code in its repair manual. So you can pin point what is the problem.

Code 42 for cadillac cimarron83 could it be the module or the ignition coil?


Code 42 has to do with your Electronic Spark Timing (EST) circuits that connect between the HEI module in the distributor and The Engine Control Module (ECM), as well as the Timing bypass connector. It can be bad wiring or connections, it can be a failed ECM or it can be a failed HEI module. There is a LONG trobleshooting chart that relates to this code but I cannot post it here. (Too big)
My recommendation is to purchase a Chilton or Haynes manual so you can have access to the chart and test the system BEFORE replacing any parts.

Emissions light is on - they tell me it's not going into 4th gear while doing highway driving. What has to be done to correct this?


Hi and welcome to FixYa!

As a first course of action please replace the oxygen sensors. When they are faulty things like this occurs. If still no luck with the oxygen sensor then the problem will surely be on the ECM (engine control module). The ECM will surely need replacement. Hope this helps and thank you for using FixYa!
