id040262005100

Outline

System malfunction location

Sophisticated Airbag Sensor (SAS) control module system

Detection condition

Note

•  The low-G sensor and the yaw rate sensor are built into the Sophisticated Airbag Sensor (SAS) control module.

•  C0061:28

―  The DSC HU/CM detects that the offset amount of the lateral-G signal is outside of the specification.

•  C0061:64

―  While driving, the DSC HU/CM determines that there is a lateral-G malfunction as a result of comparing the yaw rate, lateral-G, and the steering angle.

•  C0062:28

―  The DSC HU/CM detects that the offset amount of the longitudinal-G signal is outside of the specification.

•  C0062:64

―  The DSC HU/CM detects a mismatch between the longitudinal-G detected by the low-G sensor and the longitudinal-G calculated from the wheel speed signal.

•  C0063:28

―  The DSC HU/CM detects any of the following conditions.

•  Offset amount of yaw rate sensor signal is outside of specification

•  Difference of calculated yaw rate exceeds specification

•  C0063:64

―  While driving, the DSC HU/CM detects that there is a yaw rate malfunction as a result of comparing the yaw rate, lateral-G, and the steering angle.

Fail-safe

Refer to “DTC Table” and “Fail-safe Function Malfunction Contents Table”.(See DTC TABLE [DSC HU/CM (E)].)

Possible cause

•  Sophisticated Airbag Sensor (SAS) control module incorrect installation

•  Sophisticated Airbag Sensor (SAS) control module malfunction

―  Low-G sensor (Lateral acceleration sensor) malfunction

―  Low-G sensor (Longitudinal acceleration sensor) malfunction

―  Yaw rate sensor malfunction

•  DSC HU/CM malfunction

•  Strong impact (such as collision) occurred

Diagnostic Procedure

Step

Inspection

Results

Action

1

VERIFY IF SOPHISTICATED AIRBAG SENSOR (SAS) CONTROL MODULE IS INSTALLED CORRECTLY

•  Verify the Sophisticated Airbag Sensor (SAS) control module installation condition.
(See SAS CONTROL MODULE REMOVAL/INSTALLATION [STANDARD DEPLOYMENT CONTROL SYSTEM].)

(See SAS CONTROL MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

•  Is the installation condition normal?

Yes

Go to the next step.

No

Correctly install the Sophisticated Airbag Sensor (SAS) control module and perform the repair completion verification.

(See SAS CONTROL MODULE REMOVAL/INSTALLATION [STANDARD DEPLOYMENT CONTROL SYSTEM].)

(See SAS CONTROL MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

2

INSPECT SOPHISTICATED AIRBAG SENSOR (SAS) CONTROL MODULE FOR MALFUNCTION

•  Perform the DTC inspection for Sophisticated Airbag Sensor (SAS) control module.
(See DTC INSPECTION.)

•  Are any DTCs displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

(See DTC TABLE [SAS CONTROL MODULE (STANDARD DEPLOYMENT CONTROL SYSTEM)].)

(See DTC TABLE [SAS CONTROL MODULE (TWO-STEP DEPLOYMENT CONTROL SYSTEM)].)

No

Go to the next step.

Repair completion verification 1

VERIFY THAT VEHICLE IS REPAIRED

•  Install/connect the part removed/disconnected during the troubleshooting procedure.

•  Clear the DTC recorded in the memory.
(See CLEARING DTC.)

•  Drive the vehicle at a speed exceeding 20 km/h {12 mph}.

•  Gradually slow down and stop vehicle.

•  Perform the DTC inspection for the DSC HU/CM.
(See DTC INSPECTION.)

•  Is the same Pending DTC present?

Yes

Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.

(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(E)].)

If the CAN communication is normal, perform the diagnosis from Step 1.

•  If the malfunction recurs, replace the DSC HU/CM, then go to the next step.
(See DSC HU/CM REMOVAL/INSTALLATION [L.H.D. (E)].)

(See DSC HU/CM REMOVAL/INSTALLATION [R.H.D.].)

No

Go to the next step.

Repair completion verification 2

VERIFY IF OTHER DTCs DISPLAYED

•  Perform the DTC inspection.
(See DTC INSPECTION.)

•  Are any DTCs displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

No

DTC troubleshooting completed.
