: A second key is necessary to check the key cylinder inputs.
Be sure to rotate the key cylinder switch two
times to each position (lock and lock, unlock
and unlock) to ensure the door lock knob
switch is in the appropriate position. Go to function and input test for the system
related to the failure.
Repair the open, short, or replace the faulty
switch.

Sleep and Wake-up Mode Test
1. Shift to the sleep mode:Turn the ignition switch to LOCK (0), and remove the key. If the MICU receives no signals from the inputs listed
below, it will go into sleep mode in less than 40 seconds.
Driver’s door lock switch (LOCK or UNLOCK)
Driver’s door key cylinder switch (LOCK or UNLOCK)
Front passenger’s door lock switch (LOCK or UNLOCK)
Trunk lid latch switch (Trunk lid closed)
Hazard warning switch (OFF)
2. Confirm the sleep mode: Measure the frequency on the B-CAN communication line (PNK wire); there should be 0 Hz when the system is in
the sleep mode. Check the parasitic draw at the battery while shifting into the sleep mode; the amperage should
change from about 200 mA to less than 35 mA.
3. Shift to the wake up mode: When the ignition switch is turned to ON (II), the MICU, gauge control module, immob ilizer-keyless control unit,
and ECM/PCM 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, the control unit is followed by a list of the switches and input signals that can wake it up.
