Title: THEFT DETERRENT / KEYLESS ENTRY: SMART KEY SYSTEM (for Start Function, HV Model): Steering Lock does not Lock; 2019 - 2021 MY RAV4 HV [11/2018 - 12/2021]

Steering Lock does not Lock

DESCRIPTION

The steering lock ECU (steering lock actuator with ECU 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 Techstream with the power switch off, connect the Techstream to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the Techstream and the vehicle begins. Then select the vehicle type under manual mode and enter the following menus: Body Electrical / Smart Key. While using the Techstream, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the Techstream and the vehicle.
  • Inspect the fuses for circuits related to this system before performing the following procedure.
  • The smart key 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 key 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 the Diagnostic Trouble Code Chart.
  • After completing repairs, confirm that the problem does not recur.
  • After repair, confirm that no DTCs are output by performing "DTC Output Confirmation Operation".
  • Before replacing the steering lock ECU (steering lock actuator with ECU assembly), certification ECU (smart key ECU assembly) or ID code box (immobiliser code ECU), refer to the Registration.
