WARNING: This page is about a different car, the 2011 Acura TL, 2010 Acura TL, and 2009 Acura TL. However, it is still accessible from the selected car via links, so may be relevant.

Shift to the sleep mode:
Close all doors Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode, remove the key without keyless access system, then open and close the driver's door If the MICU receives no signals from the inputs listed below, it will go into sleep mode in less than 50 seconds.
- IG1 Power supply
- IG2 Power supply
- B-CAN data
- Trunk lid latch switch (Trunk lid closed) (OFF)
- Hazard warning switch (OFF)
Confirm the sleep mode
NOTE: Check any official Honda service website for more service information about parasitic draw at the battery

Check the parasitic draw at the battery while shifting into the sleep mode, amperage should change from about 200 mA to less than 35 mA in less than 50 seconds
Shift to the wake-up mode
When the ignition switch is turned to ON (II), or the vehicle is in ON mode The driver's MICU, passenger's MICU, gauge control module, immobilizer-keyless control unit, and PCM will wake-up at the same time without "talking" to each other through the communication lines When any switch in the multiplex integrated control system is turned on, it wakes up its related control unit which, in turn, wakes up the other units After confirming the sleep mode, look in the following table for the switch most related to the problem Operate that switch and see if its control unit wakes up

NOTE: If any control unit is faulty and will not wake up, several circuits in the system will malfunction at the same time In the table below, it is a list of the switches and input signals that can wake it up
