On Odyssey cars since 1996. and CR-V since 1997, an automatic transmission has been installed and these units have been combined into a single PCM unit that controls the power unit (engine and transmission).
PCM unit mounted:
- on CR-V models - in the cabin on the passenger side, under the front mudguard panel,
- on Odyssey models 1995-98 - in the cabin on the passenger side, under the foot rest,
- on Odyssey 1999-00 models, in the saloon under the lower part of the central floor section.
Removal and installation
The processor unit can be tested by replacing it with a known good one. In this case, the installed block must exactly match the checked one, otherwise the new block will fail. It is not allowed to operate a car with a discharged battery or a faulty voltage regulator, since the charging system of the cars in question is connected to the processor unit.
Attention! On Odyssey 2.3L 1998 and V6 1999-00 after replacement (or installation of the removed) immobilizer codes should be rewritten using the Honda PGM Tester. Otherwise, the engine will not start. To avoid the failure of the processor unit, it is forbidden to disconnect the battery from the mass with the ignition on.
CR-V and 4-cylinder Odyssey models

1. Make sure the ignition is off and disconnect the battery from the ground.
2. On CR-V models, remove the front wheel arch mudguard panel on the passenger side inside the passenger compartment.
3. On 4-cylinder Odysseys, remove the front door sill trim on the passenger side, fold down the mat and remove the processor unit cover.
4. Loosen the screws (or unfasten the latches), disconnect the connector and remove the unit.
5. The block is installed in the reverse order. On 4-cylinder Odysseys, rewrite the immobilizer codes.

1. Make sure the ignition is off and disconnect the battery from the ground.
2. Fold down the front floor mats.
3. Remove the center section bottom covers on both sides.
4. Remove the PCM cover by removing the fasteners and remove through the opening in the center section.
5. Loosen the screws (or unfasten the latches), disconnect the connector and remove the PCM unit.
6. The block is installed in the reverse order. Rewrite the immobilizer codes.
7. On Odyssey V6 models, if the PCM is checked by substitution with a known good one, do the following.
- a. Remove the blocks on both vehicles, stick labels on the blocks indicating the serial number of the car from which the block is removed.
- b. Install the unit on the vehicle to be checked.
- c. By aligning the ignition key heads with the car -"donor" and a spare key from the vehicle being checked (photo), tape them together so that the PCM can "recognize" car immobilizer code-"donor". Otherwise, the engine will not start.
- d. At the end of the test, install the blocks in their original places and disconnect the keys.
