1. Disconnect the battery
2. Locate the ECU. It's under the passenger side footwell - beneath the carpet.
3. The ECU is on the inside of a protective metal cover, which have 4x 10mm nuts holding it in place; you will need a 10mm deep socket to free the casing from the chassis.
4. Remove each of the harness that is connected to the ECU & A/T unit (TCM)
5. Unbolt the ECU from its protective cover by removing 3x 10mm bolts
6. Using a philip screwdriver, remove the lid/cover from both sides of the ECU
7. Locate the 000 ohm resistor soldered in the location of RP13
8. In addition, locate the target area RP14 on the other side of the circuit board. This location is directly on the opposite side of the board (behind RP13)
9. Very carefully de-solder the resistor use a precision 1.0 mm flat screwdriver to carefully pry the resistor from the board (careful do not break the resistor) remember time is your friend do not rush take your time.
10. After successfully removing the 000 ohm resistor from RP13 go ahead and place it on the position RP14
11. Solder both end of the resistor.
12. Screw every thing back into place in the reverse order of removal.
13. Connect the harnesses back into the ECU and then connect the battery terminals. You can remove the TCM at this point - no need for it.
14. Start your car up. CEL should be gone!
