a) Insert ignition key (1) in ignition key cylinder (2).
b) Remove ignition key from ignition key cylinder.
c) Repeat Step a) and b) twice.
d) Insert ignition key in ignition key cylinder.
e) Push lock side (3) of driver side manual lock switch (4) 3 times.
4) When Step 3) is completed, the mode changes to the next one automatically. The warning buzzer
(located in BCM) sounds by the number of specified
for each mode as follows.
• Changed from A mode to B mode: Buzzer sounds 4 times
• Changed from B mode to A mode: Buzzer sounds once

Inspection of Immobilizer Control Module (ICM) and Its CircuitS7RS0BA304018
ICM and its circuit can be checked at ICM wiring connector by measuring voltage.
CAUTION!
ICM cannot be checked by itself. It is strictly prohibited to connect voltmeter or ohmmeter to ICM with
connector disconnected from it.

Voltage Check
1) Remove ICM (1) from steering lock assembly or steering lock unit referrin g to “Immobilizer Control Module (ICM)
Removal and Installation”.
2) Connect ICM connector (2) to ICM.
3) Check voltage at each terminal.
NOTE
As each terminal voltage is affected by the battery voltage, confirm that it is 11 V or more when the
ignition switch is turned to ON position.

5 CAN communication circuit check
1) Disconnect connectors from ECM, BCM and ABS
control module.
2) Check CAN communication circuit for open, short and high resistance.
• Between ECM and ABS control module
• Between BCM and ABS control module
Is each CAN communication circuit in good condition? Go to Step 6. Repair circuit.
6 Replacement of BCM
1) Replace BCM with new one referring to “BCM (Included
in Junction Block Assembly) Removal and Installation in
Section 10B”.
2) Check ECM for DTC referring to “Diagnostic Trouble Code (DTC) Check”.
Is DTC P1638 still detected? Substitute a known-
good ECM and recheck.
BCM faulty.
