Hi Guys,

Donít pay to have your Immobilizer removed from your DC2R P73 ECU, do it your self. Just take time and some care as it is so easy to do.






Aim: Remove the Factory Immobilizer from the DC2R OBDIIa ECU


Required:

- soldering Iron
- solder
- solder sucker
- soldering skills
- Philips Head screw driver
- Anti Static Strap




Step 1

- remove the ECU from the car.
- put on the anti static wrist strap and connect the alligator connector to the body of the ecu.
- Remove the top and bottom ECU covers to expose the ECU components. The bellow pic is what you will be confronted with.




- the riser PCB in the yellow circle in the above pic is part of the immobilizer,

what we have to do is bypass it by setting a few jumpers on the ECU.

STEP 2


- locate J20 on the underside of the ECU and join it with a blob of solder.
if that is to messy and difficult for you, you can use a piece of wire and solder it in to make the bridge. see bellow pic



STEP 3

- locate RP23 on the underside of the ECU and join it with a blob of solder.
if that is to messy and difficult for you, you can use a piece of wire and solder it in to make the bridge. See bellow pic





STEP 4

- Locate RP24 on the top side of the ECU next to the MCU (yellow arrow pic bellow). You have to remove the 0 ohm resistor that is bridging the pads. Apply heat on both side of the 0 ohm resistor and pry it off with your soldering iron tip, clean up the area making sure solder is not splattered everywhere.




thatís it, your Immobilizer is bypassed. I like to remove the Immo PCB as well, makes no difference but I like to keep them as a souvenir.



so if you want to remove yours remove the thing in the yellow circle in pic bellow.



the ECU will now start any B18C in any car with out any fault codes



this type of immobilizer is a IMMO A0, as printed on the ECU, for other types of ECU'z you can remove this module to bypass the Immobilizer, however you may have a fault code constantly in the ECU.


Confirm this method works on the bellow ECU's listed ECU PCB ( M1Y-C 0014T - L5000 - 01 )

P73 from DC2R
P30 from 97 CRX
