DTC |
C1442 |
Invalid Data Received from Deceleration Sensor |
|
DTC |
C1443 |
Invalid Data Received from Yaw Rate Sensor |
DESCRIPTION
- The skid control ECU (brake actuator assembly) receives signals from the yaw rate and acceleration sensor via the CAN communication system (w/ VDIM).
- The skid control ECU (brake actuator assembly) receives signals from the yaw rate and acceleration sensor (airbag sensor assembly) via the CAN communication system (w/o VDIM).
The yaw rate sensor has a built-in acceleration sensor and detects the vehicle condition.

DTC Code |
DTC Detection Condition |
Trouble Area |
|---|---|---|
|
C1442 |
With terminal IG1 voltage between 9.5 and 17.4 V, an invalid data signal is received from the acceleration sensor for 10 seconds or more. |
|
|
C1443 |
With terminal IG1 voltage between 9.5 and 17.4 V, an invalid data signal is received from the yaw rate sensor for 10 seconds or more. |

CAUTION / NOTICE / HINT
NOTICE:
When replacing the brake actuator assembly or yaw rate and acceleration sensor, perform zero point calibration and store system information (See page
![2016 - 2017 MY Sienna [12/2015 - 11/2017]; BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: CALIBRATION](/t3Portal/stylegraphics/info.gif)
).
PROCEDURE
|
1. |
CHECK DTC |
(a) Clear the DTCs (See page
).
(b) Start and idle the engine for 60 seconds, and then stop the engine.
(c) Check if the same DTC is recorded (See page
).
