INSPECTION PROCEDURE

NOTICE:
  1. Do not remove the steering angle sensor from the spiral cable sub-assembly.
  2. After replacing the spiral cable sub-assembly, confirm that the replacement part is of the correct specification.
  3. Inspect the fuses for circuits related to this system before performing the following inspection procedure.
  4. Before disconnecting the connector, make sure that there are no problems with the connection.
  5. After disconnecting the connector, make sure that the connector case and terminals are not deformed or corroded.
HINT:
  1. When DTC U0073 and/or U0126 is output together with DTC C1432, inspect and repair the trouble areas indicated by DTC U0073 and/or U0126 first (Toyota Fortuner RM000000YUO0DYX.html).
  2. When the speed sensor or yaw rate sensor assembly has trouble, DTCs for the steering angle sensor may be stored even when the steering angle sensor is normal. When DTCs for the speed sensor or the yaw rate and acceleration sensor are output together with DTCs for the steering angle sensor, inspect and repair the speed sensor and yaw rate sensor assembly first, and then inspect and repair the steering angle sensor.
1.CHECK TERMINAL VOLTAGE (BAT TERMINAL)

  1. Turn the ignition switch off.

  1. Disconnect the steering angle sensor (spiral cable sub-assembly) connector.

3.CHECK HARNESS AND CONNECTOR (ESS TERMINAL)

  1. Turn the ignition switch off.

  1. Disconnect the steering angle sensor (spiral cable sub-assembly) connector.

  1. Measure the resistance according to the value(s) in the table below.

    Standard Resistance:
    Tester Connection
    		Condition
    		Specified Condition
    S23-2 (ESS) - Body ground
    		Always
    		Below 1 Ω
