1.

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, 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 40 seconds.

2.

Confirm sleep mode:

NOTE: Check the official Honda service website for more service information about parasitic draw at the battery.

Check the parasitic draw at the battery while entering sleep mode; amperage should change from about 200 mA to less than 35 mA in less than 40 seconds.

3.

Shift to wake-up mode:

When the ignition switch is turn to ON (II), or press the engine start/stop button to select the ON mode, the MICU, the gauge control module, the power window master switch, the power control unit, the keyless access control unit, the backup control unit, immobilizer-keyless control unit, and the 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 does not wake up, several circuits in the system malfunction at the same time. Below is a list of the switches and input signals that wake them up.
