2010 Lexus Truck RX 350 AWD V6-3.5L (2GR-FE) C CODE Page 532

INSPECTION PROCEDURE

HINT

- When DTC U0073, U0123, U0124 and/or U0126 is output together with DTC C1434, inspect and repair the trouble areas

indicated by DTC U0073, U0123, U01245 and/or U0126 first See: U Code Charts/U0073.

- When any of the speed sensors or the yaw rate and acceleration sensor has trouble, DTCs for the steering angle sensor may be

output even when the steering angle sensor is normal. When DTCs for the speed sensors or yaw rate and acceleration sensor

are output together with DTCs for the steering angle sensor, inspect and repair the speed sensor and yaw rate and acceleration

sensor first, and then inspect and repair the steering angle sensor.

PROCEDURE

1. CHECK DTC

(a) Clear the DTCs See: Brakes and Traction Control/Antilock Brakes / Traction Control Systems/Testing and Inspection/Reading and

Clearing Diagnostic Trouble Codes.

(b) Turn the engine switch off.

(c) Turn the engine switch on (IG) again and check that no CAN communication system DTC is output See: Powertrain

Management/Computers and Control Systems/Information Bus/Testing and Inspection/Initial Inspection and Diagnostic

Overview/CAN Communication System/Diagnosis System.

(d) Start the engine.

(e) Drive the vehicle and turn the steering wheel to the right and left at a speed of 35 km/h (22 mph) and check that no speed sensor or

yaw rate and acceleration sensor DTCs are output See: Brakes and Traction Control/Antilock Brakes / Traction Control

Systems/Testing and Inspection/Reading and Clearing Diagnostic Trouble Codes.

Result:

HINT

- If there is a malfunction in any of the speed sensors or the yaw rate and acceleration sensor, an abnormal value may be output

although the steering angle sensor is normal.

- If speed sensor and yaw rate and acceleration sensor DTCs are output simultaneously, repair these two sensors first and

inspect the steering angle sensor.
