C1432
BRAKE CONTROL: VEHICLE STABILITY CONTROL SYSTEM: C1432: Steering Angle Sensor Power Source Voltage Malfunction
C1432 - Steering Angle Sensor Power Source Voltage Malfunction
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 Vehicle Stability Control System.
- 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.
Standard Voltage:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (POWER SOURCE CIRCUIT)
OK -- Continue to next step.
2. INSPECT STEERING ANGLE SENSOR (GROUND TERMINAL)
(a) Turn the engine switch off.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
HINT
If troubleshooting has been carried out according to Problem Symptoms Table, refer back to the table and proceed to the next step Problem Symptoms Table.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (GROUND CIRCUIT)
OK -- REPLACE STEERING ANGLE SENSOR Removal
