PCM (Powertrain control module)

All of these installations are to be performed at your own risk!!!!

    If you need to remove the PCM for any reason, here is how you do it.

   

    Important - In order to prevent internal PCM damage, the ignition must be OFF when you disconnect or reconnect the power to the PCM.  In other words, disconnect the negative cable to the battery.

    Important - When you diagnose or replace the PCM, remove any debris from the PCM connector surfaces before servicing the PCM module connector gaskets. Ensure that the gaskets are installed correctly. The gaskets prevent intrusion into the PCM.

    Also, keep in mind if you are installing a new PCM it does need to be programmed unless you've already taken care of that.

Step 1:

    Remove the eight (8)7mm fenderwell access screws from the passenger front fenderwell.  There is also one (1) push pin.  Pull out the fenderwell cover and the PCM will be staring you in the face.  The PCM is the silver box.

 

Step 2:

    Remove the TAC Module (Throttle Actuator Control) from the front of the PCM by pulling out the three (3) 7mm bolts.  Two on the right and the PITA one on the left.    I didn't try this when I took mine out but from doing the turbo install I've found out that if you take the quarter panel screw off to the rear the actual fender can be move out from the bottom some.  The screw is on the bottom of the front quarter panel and towards the rocker panel.  The may or may not work.

Step 3:

    Disconnect the PCM electrical harness connectors.  There is one bolt on each one.  This bolt does not come all the way out.  Loosen but do not remove the PCM rear retaining fastener.  Use the rear retaining fastener as an anchor for the outer bracket.  Remove the front retaining fastener from the PCM.  Reposition the PCM outer bracket and remove the PCM from the bracket and from the vehicle.

Step 4:

    Reinstall.
