Immobilizer Function

WARNING: This page is about a different car, the 2010 Acura TL and 2009 Acura TL. 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 remote is used.

This system consists of a transponder built into the remote, a remote slot control unit, the driver's MICU (has built-in imoes unit), an immobilizer indicator, and the ECM/PCM.

When the remote (programmed by the HDS) is inserted into the remote slot and the engine start/stop switch is pressed to select the ON mode, the remote slot control unit sends power to the transponder. The transponder then sends a coded signal back to the remote slot control unit, which then sends a coded signal to the ECM/PCM and the driver's MICU (imoes unit). The ECM/PCM and driver's MICU (imoes unit) identify this coded signal, then voltage is supplied to the fuel pump.

If the wrong remote is used or the code was not received or recognized by the units, the indicator flashes once, then it blinks until the OFF mode is selected by pressing the engine start/stop button. When the OFF mode is selected by pressing the engine start/stop button, the indicator blinks ten times to signal that unit has reset correctly, then the indicator goes off.
