   • Code collation result between steering locked ECM and ID code box

   Is the displayed data [Normal]?

   Result	Proceed to
   Yes	A
   No (Replace the steering lock actuator assembly.)	B

Result: 

B 

REPLACE STEERING LOCK ACTUATOR ASSEMBLY 

Refer to REMOVAL [11/2021 - ]

Result: 

A 

See step  6

1. Using the GTS, check the following items in the [Data Monitor] of [Keyless Access with Push Button Start(Collation)].

   Refer to DATA LIST / ACTIVE TEST [11/2021 - ]

   • Steering lock lock/unlock command reception history
2. While in possession of the electrical key transmitter sub-assembly, perform engine start operations, and read data within 10 seconds after starting.

   Is the displayed data [ON (keep 10 sec)]?

   Result	Proceed to
   Yes	A
   No (Replace the smart key ECU assembly.)	B

Result: 

B 

REPLACE SMART KEY ECU ASSEMBLY 

Refer to REMOVAL [11/2021 - ]

Result: 

A 

See step  7

1. Set to ACC OFF, IGN OFF, and shift position P (AT only).
2. Using a tester, open the door, and measure the voltage between terminals of steering lock actuator assembly connector when the steering lock motor is driven.

   Connector & terminal

   F6-3 (SLR+) (+) - F6-1 (GND) (-)

   Does the voltage change as follows? When steering lock motor is in operation, 1 V or less → When steering lock motor is not in operation, 11 - 14 V

   Result	Proceed to
   Yes (Replace the steering lock actuator assembly.)	A
   No	B

Result: 

A 

REPLACE STEERING LOCK ACTUATOR ASSEMBLY 

Refer to DISASSEMBLY [11/2021 - ]

Result: 

B 

See step  8

1. Turn the ignition switch to OFF.
2. Disconnect the smart key ECU assembly connector and the steering lock actuator assembly connector.
3. Using a tester, measure the resistance between the steering lock actuator assembly connector and smart key ECU assembly connector.

   Connector & terminal

   F6-3 (SLR+) - F8-10 (SLR+)

   Is the resistance less than 10 Ω?

   Result	Proceed to
   Yes	A
   No (Repair or replace the open circuit of harness.)	B

Result: 

B 

REPAIR OR REPLACE THE OPEN CIRCUIT OF HARNESS 

Result: 

A
