|
DTC |
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.

WIRING DIAGRAM
CAUTION / NOTICE / HINT
NOTICE:
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 DTC C1432, inspect and repair the trouble areas indicated by DTC U0073, U0123, U0124 and/or U0126 first (See page
![2016 MY Sienna [12/2015 - 08/2016]; BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: U0073,U0100,U0123,U0124,U0126; Control Module Communication Bus OFF](/t3Portal/stylegraphics/info.gif)
).
- 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. |
CHECK HARNESS AND CONNECTOR (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 (spiral sensor with cable 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 |
