Identifying an ECU

Article Summary:

Here you will find information detailing how to identify your ECU.

Identifying your ECU

To identify your ECU you will need to know its generation, part number and possibly its ROM number.

Image

The ECU can be located in several places: under a metal plate in the passenger's footwell (models up to 91), in the passenger's footwell behind a plastic panel (models 92-99) or by the driver's footwell under a plastic panel (some models 2000+)

The computer is connected via three connectors that pull out when a plastic clip is pressed. Remove the computer, and with a philips screwdriver remove the metal lid from the top of the computer. There may be small daughter circuit board covering some of the main circuitry. Unscrew this and lift it out of the way.


ECU Part Numbers All Honda ECUs have a part number which is located on the side of the ECU and inside the ECU on the connector. e.g. 37820-P72-A01

The part number consists of three components:

Honda's part number for ECU, which is always 37820 Three characters (which are loosely related to the model of car/engine). e.g P72 Three characters (which are the revision of the ECU) e.g. A01


The ECU Revision Number can tell us the Transmission Type it belongs to. in 88-91 ecus (PM6, PR4, PW0, PR3, PM7):

5spd = 000, 001, 002, A00, A01, A10, J00, J001, C01, C00 Auto = J51, J50, A50, A51, 901, A60, C50, C51, X30, A80, L50, L51

92-95 ECUs (P28, P30, P61, P72, P91, P08)


5spd = 000, 001, 002, 003, 004, A00, A01, A02, C00, C01, C02, J00, J01, J02, G00, G01 Auto = J50, J51, 901, 902, C50, C51, C52, A50, A51, A52, L50, L51, G51

96-00 ECUs (P2E, P2P, P2J, P72, P73):

5spd = 000, 001, 002, 003, A00, A01, A03, C00, C01, C02, C03, J00, J01, J02, A11, C11 Auto = A70, A71, A72, A91, A92, C70, C71, C72, C91, C92

From the patterns we can learn the following:

first letter = country of orgin J = Japan C = Canada A = USA G = Europe The second digit, if 5, 7, 9 then ecu is auto usually The third digit denotes the version/variation L = California emissions or typically high altitude states as well.

The middle three characters are the most useful to identify what the ECU is. Different generation ECUs may use the same characters. e.g. a P72 OBD I ECU is different from a P72 OBD II ECU.

ECU ROM Numbers As further identification Honda ECUs have a software revision number inside the ECU. This is usually a two or three digit number stamped on the 28 pin ROM, or main processor. Accord and Prelude ECUs can use a letter and number code.
