Lexus RX (RX 350L, RX450h) 2016-2026 Repair Manual: Fail-safe Chart

FAIL-SAFE CHART

FAIL-SAFE FUNCTION

  • If a malfunction is detected in the 4WD ECU assembly, the 4WD ECU assembly may stop AWD control and transfer all torque to the front wheels, or function in a such a way as to prevent damage to the system.
  • If a malfunction is detected in the sensor or actuator, current to the 4WD linear solenoid of the electro magnetic control coupling sub-assembly is cut. As a result, all torque is transferred to the front wheels.
  • When a malfunction is detected in the AWD system, operations related to the malfunction will be prohibited. However, if the function is operating when the fail-safe function activates, the operation may be permitted to continue temporarily to prevent sudden changes in the vehicle condition.
  • When the AWD system is malfunctioning, a warning message is displayed on the multi-information display to inform the driver.
