Steering Angle Sensor Power Source Voltage Malfunction

Steering angle sensor power supply malfunction signal is received from steering angle sensor.

  • ECU-B NO. 1 fuse

  • ECU-IG NO. 1 fuse

  • Steering angle sensor (Spiral with sensor cable sub-assembly)

  • Wire harness or connector

WIRING DIAGRAM

C279156E07

CAUTION / NOTICE / HINT

Note:

  • Do not remove the steering angle sensor from the spiral with sensor cable sub-assembly.

  • When replacing the steering angle sensor (spiral with sensor cable sub-assembly), confirm that the replacement part is of the correct specification.

  • Inspect the fuses for circuits related to this system before performing the following inspection procedure.

Tip:

  • When U0073, U0124 and/or U0126 is output together with C1432, inspect and repair the trouble areas indicated by U0073, U0124 and/or U0126 first.

  • When the speed sensor or the yaw rate sensor (airbag sensor assembly) has trouble, DTCs for the steering angle sensor (spiral with sensor cable sub-assembly) may be output even when the steering angle sensor is normal. When DTCs for the speed sensor or yaw rate sensor (airbag sensor assembly) are output together with DTCs for the steering angle sensor (spiral with sensor cable sub-assembly), inspect and repair the speed sensor and yaw rate sensor (airbag sensor assembly) first, and then inspect and repair the steering angle sensor (spiral with sensor cable sub-assembly).

PROCEDURE

  1. CHECK TERMINAL VOLTAGE (BAT TERMINAL)
