DTC |
C00631F |
Yaw Rate Sensor Circuit Intermittent |
|
DTC |
C05201F |
Multi-axis Acceleration Sensor Module "A" Circuit Intermittent |
DESCRIPTION
The yaw rate and acceleration sensor has a built-in airbag ECU assembly.
The No. 2 skid control ECU (brake actuator assembly) receives signals from the yaw rate and acceleration sensor (airbag ECU assembly) via CAN communication.

Note |
|---|---|---|---|---|---|
|
C00631F |
Yaw Rate Sensor Circuit Intermittent |
When voltage at terminal +BS is 9.5 to 17.4 V, sensor invalid information received from yaw rate sensor is ON continuously for 10 seconds or more. |
Yaw rate sensor (airbag ECU assembly) |
Does not come on |
Output ECU: No. 2 skid control ECU (brake actuator assembly) |
|
C05201F |
Multi-axis Acceleration Sensor Module "A" Circuit Intermittent |
When voltage at terminal +BS is 9.5 to 17.4 V, sensor invalid information received from acceleration sensor is ON continuously for 10 seconds or more. |
Acceleration sensor (airbag ECU assembly) |
Comes on |
|
MONITOR DESCRIPTION
When an invalid GL1 or GL2 signal from the yaw rate and acceleration sensor (airbag ECU assembly) is received, the No. 2 skid control ECU (brake actuator assembly) judges that the yaw rate and acceleration sensor (airbag ECU assembly) is malfunctioning, the MIL is illuminated and a DTC is stored.

CONFIRMATION DRIVING PATTERN
NOTICE:
When performing the normal judgment procedure, make sure that the driver door is closed and is not opened at any time during the procedure.
HINT:
- After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
- When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
- Connect the GTS to the DLC3.
- Turn the ignition switch to ON and turn the GTS on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off.
- Turn the ignition switch to ON (READY) and turn the GTS on.
-
Wait for 10 seconds or more. [*]
HINT:
[*]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- Enter the following menus: Chassis / Brake/EPB / Utility / All Readiness.
-
Check the DTC judgment result.
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE, perform driving pattern again.
CAUTION / NOTICE / HINT
NOTICE:
After replacing or reinstalling the yaw rate and acceleration sensor (airbag ECU assembly), perform "Calibration" after performing "Reset Memory".
