REPAIR OR REPLACE THE OPEN CIRCUIT OF HARNESS 

Result: 

A 

See step  5

1. Using a tester, measure the resistance between the steering lock actuator assembly connector and chassis ground.

   Connector & terminal

   F6-1 (GND) - Chassis ground

   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 

See step  6

1. Connect the disconnected connectors.
2. Using a tester, measure the voltage between steering lock actuator assembly terminals right after the ignition switch is turned to ON.

   Connector & terminal

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

   Is the voltage 1 V or less right after the ignition ON?

   Result	Proceed to
   Yes (Replace the steering lock actuator assembly.)	A
   No (Repair or replace the open circuit of harness.)	B

Result: 

A 

REPLACE STEERING LOCK ACTUATOR ASSEMBLY. Refer to  DISASSEMBLY [11/2021 - ] 

Result: 

B 

REPAIR OR REPLACE THE OPEN CIRCUIT OF HARNESS 

1. Turn the ignition switch to ON.
2. 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 - ]

   • Code collation result between smart ECM and immobilizer code ECU

   Is the displayed data [Normal]?

   Result	Proceed to
   Yes	A
   No	B

Result: 

B 

See step  11

Result: 

A 

See step  8

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 - ]

   • Code collation result between steering locked ECM and immobilizer code ECU

   Is the displayed data [Normal]?

   Result	Proceed to
   Yes (The circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.) HINT:  In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.	A
   No	B

Result: 

A 

THE CIRCUIT HAS RETURNED TO A NORMAL CONDITION AT THIS TIME 

The circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.

HINT: 

In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.

Result:

See step  9

1. Turn the ignition switch to OFF.
2. Replace with a properly functioning or new steering lock actuator assembly..

   Refer to REMOVAL [11/2021 - ]

3. After registering, the steering lock operates when the ignition is turned to OFF and the driver's door is opened and closed.
4. Turn the ignition to ON.
5. Operate the steering and check for whether the steering lock is released.

   Is the steering lock released, and does the engine start?

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