Title: BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: C1432; Steering Angle Sensor Power Source Voltage Malfunction; 2018 - 2020 MY Sienna [11/2017 - ] |
DTC
|
C1432
|
Steering Angle Sensor Power Source Voltage Malfunction
|
DESCRIPTION
The skid control ECU (brake actuator assembly) outputs this DTC when it receives a sensor power source malfunction signal from the steering angle sensor (spiral cable with sensor sub-assembly).
DTC No.
|
DTC Detection Condition
|
Trouble Area
|
C1432
|
Steering angle sensor power supply malfunction signal is received from steering angle sensor.
|
-
Wire harness or connector
-
Steering angle sensor (Spiral Cable with Sensor Sub-assembly)
|
WIRING DIAGRAM
CAUTION / NOTICE / HINT
NOTICE:
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 (See page
).
-
When the speed sensor or the yaw rate sensor (airbag sensor assembly) has trouble, DTCs for the steering angle sensor (spiral cable with sensor sub-assembly) may be output even when the steering angle sensor (spiral cable with sensor sub-assembly) 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 cable with sensor 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 cable with sensor sub-assembly).
PROCEDURE
1.
|
CHECK HARNESS AND CONNECTOR (BAT TERMINAL)
|
(a) Remove the steering wheel and the column cover.
|
|
(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 (spiral cable with sensor sub-assembly) connector.
(d) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection
|
Switch Condition
|
Specified Condition
|
D22-5 (IG) - Body ground
|
Ignition switch ON
|
11 to 14 V
|
D22-6 (BAT) - Body ground
|
Always
|
11 to 14 V

REPAIR OR REPLACE HARNESS OR CONNECTOR (POWER SOURCE CIRCUIT)
|
OK
|
|
|
2.
|
CHECK HARNESS AND CONNECTOR (ESS TERMINAL)
|
(a) Turn the ignition switch off.
|
|
(b) Measure the resistance according to the value(s) in the table below.
NOTICE:
Before measuring the resistance of the steering angle sensor (spiral cable with sensor sub-assembly), turn the ignition switch off and leave the vehicle for 1 minute or more without operating the key, switches or opening or closing the doors.
Standard Resistance:
Tester Connection
|
Switch Condition
|
Specified Condition
|
D22-2 (ESS) - Body ground
|
1 minute after ignition switch off
|
Below 1 Ω
