Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - STEERING COLUMN


POWER TILT AND POWER TELESCOPIC STEERING COLUMN SYSTEM - FAIL-SAFE CHART

  • HINT:
  • If the power source voltage to the tilt and telescopic ECU returns to normal within 10 seconds during tilt or telescopic operation, the operation will be resumed. If it returns to normal after 10 seconds have elapsed, the operation restarts when a tilt or telescopic operation signal is again input to the tilt and telescopic ECU.

FAIL-SAFE FUNCTION

If a malfunction in the tilt position sensor signal or telescopic position sensor signal occurs while operating the power tilt or power telescopic function, the tilt and telescopic ECU stops the operation of the power tilt and power telescopic steering column system.

If the power source voltage to the ECU drops below approximately 8 V while operating the power tilt or power telescopic function, the ECU stops the operation of the power tilt and power telescopic steering column system.

If the tilt and telescopic ECU detects that the motor has locked during the operation of the power tilt or power telescopic function, the ECU stops the operation of the power tilt and power telescopic steering column system.

If the communication of an ECU that is related to the power tilt and power telescopic steering column system is interrupted, the tilt and telescopic ECU cannot control the functions listed below.
