C1432

BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: 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

NOTICE:
* Do not remove the steering sensor from the spiral with sensor cable sub-assembly.
* When replacing the 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.

HINT
* When DTC U0073, U0123, U0124 and/or U0126 is output together with C1432, inspect and repair the trouble areas indicated by U0073, U0123, U0124 and/or U0126 first U0073.
* When the speed sensor or the yaw rate and acceleration sensor 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 the yaw rate and acceleration sensor first, and then inspect and repair the steering angle sensor.

PROCEDURE

1. CHECK TERMINAL VOLTAGE (IG/BAT)

(a) Make sure that there is no looseness in the locking part and connecting part of the connectors.





(b) Disconnect the steering angle sensor connector.

(c) Measure the voltage according to the value(s) in the table below.

Standard Voltage:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (IG/BAT CIRCUIT)
OK -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (ESS TERMINAL)

(a) Disconnect the steering angle sensor connector.





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

Standard Resistance:

If troubleshooting has been carried out according to Problem Symptoms Table, refer back to the table and proceed to the next suspected area Problem Symptoms Table

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (ESS CIRCUIT)

OK -- REPLACE SPIRAL WITH SENSOR CABLE SUB-ASSEMBLY Removal
