Immobilizer code is not identified:
WARNING: This page is about a different car, the 2016 Acura RDX, 2015 Acura RDX, 2014 Acura RDX, and 2013 Acura RDX. However, it is still accessible from the selected car via links, so may be relevant.
Perform bulb check on gauge control module before performing F-CAN diagnostics. When pressing the engine start/stop button to select the ON mode when the immobilizer code has not been identified, the immobilizer indicator will come on for 2 seconds, then blink until the OFF mode is selected. The state of keyless registration and the S-NET line can be checked by doing a system check and a status log check with the HDS.
When in the OFF mode, the immobilizer indicator will blink 10 times to signal that until it has been reset correctly, the immobilizer indicator will remain off.
