DTC C1432 Steering Angle Sensor Power Source Voltage Malfunction |
DESCRIPTION
Steering angle sensor signals are sent to the skid control ECU (brake actuator assembly) 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.DTC No.
| DTC Detection Condition
| Trouble Area
|
C1432
| Steering angle sensor power supply malfunction signal is received from steering angle sensor.
| - Steering angle sensor power supply
- Steering angle sensor (Spiral cable sub-assembly)
|
WIRING DIAGRAM
INSPECTION PROCEDURE
- NOTICE:
- Do not remove the steering sensor from the spiral cable.
- When replacing the spiral cable, 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 U0073, U0124 and/or U0126 is output together with C1432, inspect and repair the trouble areas indicated by U0073, U0124 and/or U0126 first (YARIS_NCP93 RM000000YUO0EPX.html).
- When the speed sensor or the Yaw rate and deceleration sensor (Airbag sensor assembly) has trouble, DTCs for the steering angle sensor (spiral cable sub-assembly) may be output even when the steering angle sensor is normal. When DTCs for the speed sensor or Yaw rate and deceleration sensor (Airbag sensor assembly) are output together with DTCs for the steering angle sensor (spiral cable sub-assembly), inspect and repair the speed sensor and Yaw rate and deceleration sensor (Airbag sensor assembly) first, and then inspect and repair the steering angle sensor (spiral cable sub-assembly).
| 1.CHECK TERMINAL VOLTAGE (BAT TERMINAL) |
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
Tester Connection
| Switch Condition
| Specified Condition
|
D122-6 (BAT) - Body ground
| Always
| 11 to 14 V
|

|
| | REPAIR OR REPLACE HARNESS OR CONNECTOR (POWER SOURCE CIRCUIT) |
|
|
| 2.CHECK TERMINAL VOLTAGE (IG TERMINAL) |
Remove the steering wheel and the column cover lower.
Make sure that there is no looseness at the locking part and the connecting part of the connectors.
Disconnect the steering angle sensor connector.
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
Tester Connection
| Switch Condition
| Specified Condition
|
D122-5 (IG) - Body ground
| Ignition switch ON
| 11 to 14 V
|

| | REPAIR OR REPLACE HARNESS OR CONNECTOR (POWER SOURCE CIRCUIT) |
|
|
| 3.CHECK HARNESS AND CONNECTOR (ESS TERMINAL) |
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection
| Condition
| Specified Condition
|
D122-2 (ESS) - Body ground
| Always
| Below 1 Ω
|
- HINT:
- If troubleshooting has been carried out according to the Problem Symptoms Table, refer back to the table and proceed to the next step (YARIS_NCP93 RM000000XHN0BRX.html)
