System Description

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 Honda Odyssey, 2016 Honda Odyssey, 2015 Honda Odyssey, 2014 Honda Odyssey, and 2013 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.

The vehicle is equipped with a Type VII (GEN 5) immobilizer system that disables the vehicle unless a programmed ignition key is used.

This system consists of a transponder combined with a keyless transmitter, an immobilizer-keyless control unit (has built-in receiver), the MICU (has built-in IMOES unit), an immobilizer indicator, and the PCM.

When the immobilizer key (programmed by the HDS) is inserted into the ignition switch and turned to ON (II), the immobilizer-keyless control unit sends power to the transponder. The transponder then sends a coded signal back to the immobilizer-keyless control unit which then sends a coded signal to the PCM and the MICU (IMOES unit).

The PCM and MICU (IMOES unit) identify this coded signal, then voltage is supplied to the fuel pump.

If the wrong key is used or the code was not received or recognized, the indicator flashes once, then it blinks until the ignition switch is turned to LOCK (0). When the ignition switch is turned to the LOCK (0) position, the indicator blinks ten times to signal that unit has reset correctly, then the indicator goes off.
