WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2014 Honda Ridgeline, 2013 Honda Ridgeline, 2012 Honda Ridgeline, 2011 Honda Ridgeline, and 2010 Honda Ridgeline. However, it is still accessible from the selected car via links, so may be relevant.
When the ignition switch is turned to ON (II) but the immobilizer code is not identified, the immobilizer indicator comes on for 2 seconds, then blinks. The state of the immobilizer key registration and the IMOCD line can be checked by doing a SYSTEM CHECK (see System Check ) and STATUS LOG CHECK (see Status Log ) with the HDS.
The immobilizer indicator goes off when the ignition switch is turned to LOCK (0).
