DTC C1232 Acceleration Sensor Stuck Malfunction |
DTC C1243 Acceleration Sensor Stuck Malfunction |
DTC C1245 Acceleration Sensor Output Malfunction |
DESCRIPTION
The skid control ECU receives signals from the yaw rate and deceleration sensor via the CAN communication system.The yaw rate sensor has a built-in deceleration sensor and detects the vehicle condition using 2 circuits (GL1, GL2).If there is trouble in the bus lines between the yaw rate and deceleration sensor and the CAN communication system, DTCs U0123 (malfunction in CAN communication with the yaw rate sensor) and U0124 (malfunction in CAN communication with the acceleration sensor) are stored.DTC Code
| DTC Detection Condition
| Trouble Area
|
C1232
| At a vehicle speed of 10 km/h (6 mph) or more, acceleration sensor output value does not change for 30 seconds or more.
| - Sensor installation
- Yaw rate and deceleration sensor
|
C1243
| While the vehicle speed changes from 30 km/h (19 mph) to 0 km/h (0 mph), the condition that the value of acceleration sensor does not change by 0.0294 G or more occurs 16 times or more.
| - Sensor installation
- Yaw rate and deceleration sensor
|
C1245
| At a vehicle speed of 30 km/h (19 mph) or more, the difference between the forward and backward G calculated from the acceleration sensor value and that calculated from the vehicle speed sensor exceeds 0.35 G for 60 seconds or more.
| - Sensor installation
- Yaw rate and deceleration sensor

INSPECTION PROCEDURE
- NOTICE:
- When replacing the yaw rate sensor assembly, perform zero point calibration (RAV4_ACA30 RM000001K1O00SX.html).
- HINT:
- When U0123, U0124 and/or U0126 is output together with C1232, C1243, and/or C1245, inspect and repair the trouble areas indicated by U0123, U0124 and/or U0126 first (RAV4_ACA30 RM000000YUO048X.html).
| 1.CHECK YAW RATE AND DECELERATION SENSOR INSTALLATION |
Check that the yaw rate and deceleration sensor has been installed properly (RAV4_ACA30 RM000001XVO00CX_01_0001.html).
- OK:
- The sensor should be tightened to the specified torque.
- The sensor should not be installed in a tilted position.
- NOTICE:
- Check the yaw rate and deceleration sensor signal after replacement (RAV4_ACA30 RM0000022CZ007X.html).
- HINT:
- If troubleshooting has been carried out according to the Problem Symptoms Table, refer back to the table and proceed to the next step (RAV4_ACA30 RM000000OS701UX.html).
