DTC C0061:54, C0062:54 OR C0063:54 [DSC HU/CM]

id040262005200

Outline

System malfunction location

DSC HU/CM system (unperformed initialization procedure)

Detection condition

Note

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

•  C0061:54

―  The DSC HU/CM detects that the lateral-G sensor value initialization was not implemented.

•  C0062:54

―  The DSC HU/CM detects that the longitudinal-G sensor value initialization was not implemented.

•  C0063:54

―  The DSC HU/CM detects that the yaw rate sensor value initialization was not implemented.

Fail-safe

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

Possible cause

•  The initialization procedure for the lateral acceleration sensor has not been performed.

•  The initialization procedure for the longitudinal acceleration sensor has not been performed.

•  The initialization procedure for the yaw rate sensor has not been performed.

•  Sophisticated Airbag Sensor (SAS) control module malfunction

―  Low-G sensor malfunction

―  Yaw rate sensor malfunction

•  DSC HU/CM malfunction

Diagnostic Procedure

Step

Inspection

Results

Action

1

VERIFY SENSOR INITIALIZATION PERFORMANCE CONDITION FOR DSC-RELATED PARTS

•  Has the sensor initialization for the DSC-related parts been performed?

Yes

Go to the next step.

No

Perform the sensor initialization for the DSC-related parts and perform repair completion verification.

(See DSC RELATED PARTS SENSOR INITIALIZATION PROCEDURE [(E)].)

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.)

•  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.
