LOCATING YOUR ECU...

  Locate the ECU, it is housed in a plastic box behind the passenger side headlamp. (Photo Below). To remove the access cover, use a 6-8” flat blade screwdriver to gently unlatch the cover retaining clips as shown below. There are 2 clips, one on the engine side of the plastic box and one on the side next to the fender. Place the tip of the screwdriver under the bottom of the clip, pry it away from the box and lift up on the cover a bit so the clip will dis-engage from the lower portion of the box.

Grab the coolant / power steering fluid reservoir as shown in photo #3 and lift it upwards until it snaps out of it’s mounting brackets. (this may take a bit of force) This will make removal and replacement of the box cover easier. Note that the 2 upper attachment points for the reservoir assembly are clearly visible. There is also a 3rd attachment point just below the upper attachment point closest to the engine. Be sure that this is engaged when you snap the reservoirs back into place. You should now be able to lift the cover away from the lower housing . Remove the cover from the air pipe and set the cover out of the way. NOTE: The example shown in photo#4  is a manual transmission car, so there is only one ECU shown. Cars with automatic transmission will have two ECUs, The ECU closest to the engine is the auto trans ECU. There is no need to remove it.

The side of the tool that should be closest to the fender has the bend in it. Insert the tool at approximately a 45 degree angle so that it lines up with and is guided by the guide rails on the side of the ECU as shown in photo #5. Insert the tool until the pivot pins on the outer sides of the tool are fully seated into the “V” notches at the base of the control unit housing. It may be necessary to manipulate the tool a bit so that the tips of the tool can be fully inserted. Confirm that the pivot pins are fully seated and then carefully push on the handle of the tool toward the firewall of the car as shown in photo #6 while simultaneously applying downward pressure on the tool to keep it seated. Stop when the tool handle is vertical as shown in the photo #7. Once the handle of the tool is in the vertical position as shown in photo #7, you should be able to lift the tool away and then pull the ECU straight up and out of the housing. Close the hood of the car to prevent anything from getting into the open ECU socket. Did you follow the warning at the top of these instructions? 

Be sure to keep the tool for re-installation!

RE-INSTALLATION OF YOUR CHIPPED ECU...

When your upgraded ECU is returned, confirm that it is your original ECU by comparing the numbers recorded on your data sheet. Install the ECU into the housing by carefully aligning the guide rails on the edges of the ECU with the plastic guide channels in the ECU housing box, insert until the ECU is squarely seated into the socket. As described before, the side of the tool that should be closest to the fender has the bend in it. Now carefully insert the tool in the vertical position as shown in photo #8. Insert the tool until the pivot pins on the outer sides of the tool are fully seated into the “V” notches at the base of the control unit housing. It may be necessary to manipulate the tool a bit so that the tips of the tool can be fully inserted. Confirm that the pivot pins are fully seated and then carefully pull the handle of the tool toward the front of the car as shown while simultaneously applying downward pressure on the tool to keep it seated and pressing downward on the ECU with your free hand to assist seating. Stop when the tool handle is lined up with the angled guide rails on the side of the ECU as shown in the photo #9. If you experience resistance in getting the handle all the way to the angled position, apply more downward pressure to the ECU while pulling on the handle. The tool should now be easy to remove by pulling it upwards at the angle of the guide rails. Check that the ECU is solidly mated to the socket. Prepare to replace the plastic cover. Lift the reservoirs out of the way so that the cover can be placed directly on top of the housing. When it appears to be correctly positioned, press down on the cover to engage the metal clips to the lower housing. Now align all 3 of the mounting points (2 upper and 1 lower) on the reservoir assembly and press it into place. Make sure that the plastic ears are fully seated onto the brackets. Remember to immediately return your removal/installation tool to INMotionUSA or you will be charged $100.00.
