The Steering Lock cannot be Released (except for c0 Model) [11/2021 - ]: Procedure

1. Depress the brake pedal (AT mdoel) or clutch pedal (MT model).
2. While turning the steering wheel lightly to the left and right, press the engine switch.
3. Confirm that the steering lock is released and the engine starts.

   Does the engine fail to start with the steering lock released?

   Result	Proceed to
   Yes (Perform the diagnosis for engine system.)	A
   No	B

Result: 

A 

PERFORM THE DIAGNOSIS FOR ENGINE SYSTEM. Refer to  HOW TO PROCEED WITH TROUBLESHOOTING [11/2021 - ] 

Result: 

B 

See step  2

1. Turn the ignition switch to ON.
2. Read the DTC of [Keyless Access with Push Button Start(Collation)] using the GTS.

   Are any DTCs displayed? (Current code)

   Result	Proceed to
   Yes (Perform the diagnosis for the displayed DTCs.)	A
   No	B

Result: 

A 

PERFORM THE DIAGNOSIS FOR THE DISPLAYED DTCs 

Result: 

B 

See step  3

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 unlock request reception status
   • Steering lock lock/unlock command reception history
2. Read the data when the engine switch is pressed while carrying the electrical key transmitter sub-assembly. (Maintain for 10 seconds after switch operation)

   Does the data display [Not yet received] → [Reception (keep 10 sec)] and [OFF] → [ON (keep 10 sec)]?

   Result	Proceed to
   Yes	A
   No	B

Result: 

B 

See step  7

Result: 

A 

See step  4

1. Turn the ignition switch to OFF.
2. Disconnect the steering lock actuator assembly connector.
3. Using a tester, measure the voltage between the steering lock actuator assembly connector and chassis ground.

   Connector & terminal

   F6-7 (+B) (+) - Chassis ground (-)

   Is the voltage 10 V or more?

   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  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 OFF.
2. Replace with a properly functioning or new steering lock actuator assembly.

   Refer to DISASSEMBLY [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 (Replace the smart key ECU assembly.)	B

Result: 

A 

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

Result: 

B 

REPLACE SMART KEY ECU ASSEMBLY. Refer to  REMOVAL [11/2021 - ]
