CODE No. C2331 Yaw rate signal error
| caution | Before replacing the ECU, ensure that the power supply circuit, the earth circuit and the communication circuit are normal. |
OPERATION
The BSW-ECU (master) receives G and yaw rate sensor signal from the ASC-ECU via the gateway-ECU through the CAN bus lines.
CHECK CONDITION
Ignition switch is in the "ON" position.
DIAGNOSTIC FUNCTION AND JUDGEMENT CRITERIA
When the BSW-ECU (master) receives an invalid G and yaw rate sensor signal from the ASC-ECU, the ECU will set diagnosis code No. C2331.
PROBABLE CAUSES
- The ASC system fails
- Malfunction of BSW-ECU (master)
DIAGNOSIS PROCEDURE
1. M.U.T.-IIISE ASC system diagnosis code.
2. Check whether the diagnosis code is set again.
