DTC B2782: Steering Lock Drive Request Signal Correlation [11/2021 - ]: Procedure

1. Disconnect the steering lock actuator assembly connector.
2. 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 1 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  2

1. Connect the steering lock actuator assembly connector.
2. Set to ACC OFF, IGN OFF, and shift position P (AT only).
3. 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	A
   No	B

Result: 

B 

See step  4

Result: 

A 

See step  3

1. Turn the ignition switch to ON.
2. Using the GTS, perform the clear DTCs of [Keyless Access with Push Button Start(Collation)].
3. Turn the ignition switch to OFF.
4. Disconnect the ground terminal from the battery sensor and reconnect it, then clear the abnormal information displayed on [Data Monitor].
5. Turn the ignition switch to ON.
6. Read the DTC of [Keyless Access with Push Button Start(Collation)] using the GTS.

   Is DTC B2782 displayed? (Current code)

   Result	Proceed to
   Yes (Replace the steering lock actuator assembly.)	A
   No (Even if DTC is displayed, 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.	B

Result: 

A 

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

Result: 

B 

END 

1. Even if DTC is displayed, the circuit has returned to a normal condition at this time.
2. 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.

1. Disconnect the steering lock actuator assembly connector.
2. Disconnect the smart key ECU assembly connector.
3. Check each connector.

   Is the check result OK?

   Result	Proceed to
   Yes	A
   No (Repair or replace the connector.)	B

Result: 

B 

REPAIR OR REPLACE THE CONNECTOR 

Result: 

A 

See step  5

1. Using a tester, measure the resistance between smart key ECU assembly connector and steering lock actuator assembly connector.

   Connector & terminal

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

   Is the resistance less than 1 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. Using a tester, measure the resistance between the smart key ECU assembly connector and chassis ground.

   Connector & terminal

   F8-10 (SLR+) - Chassis ground

   Is the resistance 10 kΩ or more?

   Result	Proceed to
   Yes (Replace the smart key ECU assembly.)	A
   No (Repair or replace the short circuit of the harness.)	B

Result: 

A 

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

Result: 

B 

REPAIR OR REPLACE THE SHORT CIRCUIT OF THE HARNESS
