Immobilizer Information

The PCM is part of the immobilizer system. If you substitute a known-good PCM, the PCM will have a different immobilizer code. In order for the engine to start, you must rewrite the immobilizer code with the Honda PGM Tester.

If the inspection for a particular code requires voltage or resistance checks at the PCM connectors, remove the right door sill molding. Pull the carpet back to expose the PCM. Unbolt the PCM cover, and connect the backprobe sets and a digital multimeter as described below. Check the system according to the procedure described for the appropriate code(s).
