Door Lock Operation (Keyless Start System)S7RS0BA504012
1) Check that all door locks are released and all doors are closed.
2) With remote controller of which ID code is registered in keyless start control m odule carried with yourself,
check that pushing driver door, passenger door or
rear end door request switch once locks all doors.
3) Check that pushing request switch of driver door, passenger door or rear end door once releases all
door locks.
Inspection of Keyless Start Control Module and Its CircuitsS7RS0BA504013
Keyless start control module and its circuits can be che cked at keyless start control module wiring couplers by
measuring voltage and resistance.
CAUTION!
Keyless start control module cannot be checked by itself. It is strictly prohibited to connect voltmeter
or ohmmeter to keyless start control module with coupler disconnected from it.
Voltage Check
1) Disconnect negative (–) cable at battery.
2) Remove keyless start control module from vehicle body referring to “Keyless Start Control Module Removal and
Installation”.
3) Connect connector to keyless start control module.
4) Check voltage at each terminal number of couplers connected.
NOTE
• As each terminal voltage is affected by the battery voltage, confirm that it is 11 V or more when ignition switch is ON.
• Voltage with asterisk (*) cannot be measured by voltmeter because it is pulse signal.

DTC No. 51 / No. 52 / No. 53: Driver Side / Passenger Side / Rear End Door Request Switch FailureS7RS0BA504022
Wiring Diagram3
CAN communication circuit check
1) Turn ignition switch to OFF position.
2) Disconnect connectors of all control modules
communicating by means of CAN.
3) Check CAN communication circuit between control modules for open, short and high resistance.
Is each CAN communication circuit in good condition? Go to Step 4. Repair circuit.
4 DTC check of keyless start control module
1) Turn ignition switch to OFF position.
2) Connect connectors of disconnected control modules
communicating by means of CAN.
3) Disconnect connector of any one control module other than keyless start control module.
4) Recheck keyless start control module for DTC.
Is DTC No.33 detected? Using same method,
disconnect connectors
of control module other
than keyless start
control module one by
one to check if DTC
No.33 is detected.
If DTC No.33 is
detected even through
connector of control
module other than
keyless start control
module is disconnected,
substitute a known-
good keyless start
control module and
recheck.Check power and
ground circuit of
disconnect control
module. If circuit is OK,
substitute a known-
good disconnected
control module and
recheck.
