RM3660EC _58 Vehicle Interior _080747 THEFT DETERRENT / KEYLESS ENTRY _0586354 SMART ENTRY AND START SYSTEM(for Start Function, Gasoline Model (NR Series)) J

THEFT DETERRENT / KEYLESS ENTRY  SMART ENTRY AND START SYSTEM(for Start Function, Gasoline Model (NR Series))  Steering Lock does not Lock  


DESCRIPTION

The steering lock actuator or upper bracket assembly activates the steering lock motor and moves the lock bar into the steering column to lock the steering.

When the steering lock is operating, the steering may not lock when the lock bar is not aligned with the lock hole of the steering column. In this case, the steering can be locked by turning the steering wheel a little, as is done for a vehicle with a mechanical key, to change the position of the lock hole.

CAUTION / NOTICE / HINT

NOTICE:
·

When using the GTS with the engine switch off, connect the GTS to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the GTS and the vehicle begins. Then select Model Code "KEY REGIST" under manual mode and enter the following menus: Body Electrical / Entry&Start(CAN). While using the GTS, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the GTS and the vehicle.

·

Perform either of the following operations to lock/unlock the steering:

-

To unlock the steering, carry the key and turn the engine switch on (ACC) or on (IG).

-

To lock the steering, turn the engine switch off with the shift lever in P, and then open a door.


·

The smart entry and start system (for Start Function) uses the LIN communication system and CAN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the smart entry and start system (for Start Function) after confirming that the communication systems are functioning properly.

·

Make sure that no DTCs are output. If any DTCs are output, proceed to Diagnostic Trouble Code Chart.

·

Inspect the fuses for circuits related to this system before performing the following procedure.

·

Before replacing the steering lock ECU (steering lock actuator or upper bracket assembly), certification ECU (smart key ECU assembly) or ID code box (immobiliser code ECU), refer to Service Bulletin.

·

After performing repairs, confirm that the problem does not recur.

·

When disconnecting the cable from the negative (-) battery terminal, some systems need to be initialized after the cable is reconnected.
