DTC C0062:76 [DSC HU/CM]

id040262005300

Outline

System malfunction location

Sophisticated Airbag Sensor (SAS) control module (poor installation)

Detection condition

Note

•  The low-G sensor is built into the Sophisticated Airbag Sensor (SAS) control module.

•  While driving, the DSC HU/CM detects that the longitudinal-G value does not change as a result of comparing it to the longitudinal-G calculated from the wheel speed.

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 malfunction

•  DSC HU/CM malfunction

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.)

•  Start the engine and drive the vehicle at a vehicle speed exceeding 70 km/h {43 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.
