DESCRIPTION
Steering angle sensor signals are sent to the skid control ECU via the CAN communication system. When there is a malfunction in the CAN
communication system, it will be detected by the steering angle sensor zero point malfunction diagnostic function.

INSPECTION PROCEDURE
HINT
- When DTC U0073, U0123, U0124 and/or U0126 is output together with DTC C1432, inspect and repair the trouble areas
indicated by DTC U0073, U0123, U0124 and/or U0126 first See: U Code Charts/U0073.
- When the speed sensor 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 sensor 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. INSPECT STEERING ANGLE SENSOR (POWER SOURCE TERMINAL)
(a) Remove the steering wheel and the column cover lower.
(b) Make sure that there is no looseness at the locking part and the connecting part of the connectors.
(c) Disconnect the steering angle sensor connector.
(d) Measure the voltage according to the value(s) in the table below.
