System Wiring Diagram

• Not applicable

Function Explanation (DTC Detection Outline)

• During a collision, the SAS control module sends a collision signal to the PCM via the CAN signal. The PCM records a DTC by receiving a collision signal.

• This DTC does not indicate a part malfunction. It indicates operation of fail-safe from safety assurance during a vehicle collision.

Repeatability Verification Procedure

1. Switch the ignition ON and leave for 5 s or more.

2. Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC.)

3. After switching the ignition off, switch the ignition back ON and leave for 5 s or more.

Function Inspection Using M-MDS

Step

Inspection

Results

Action

1

PURPOSE: RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION

•  Record the freeze frame data/snapshot data.

Note

•  Recording can be facilitated using the screen capture function of the PC.

—

Go to the next step.

2

PURPOSE: VERIFY RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY

•  Verify related Service Bulletins, on-line repair information, or Service Information availability.

•  Is any related Information available?

Yes

Perform repair or diagnosis according to the available information.

•  If the vehicle is not repaired, go to the next step.

No

Go to the next step.

3

PURPOSE: VERIFY IF OPERATION IS NORMAL AFTER VEHICLE COLLISION

•  Ask customer about vehicle collision experience.

•  Has the vehicle in for servicing been involved in a collision in which the air bag is deployed?

Yes

Explain to the customer that the DTC is recorded as a result of a vehicle collision.

Go to Troubleshooting Diagnostic Procedure to perform the procedure from step 1.

No

Go to the next step.

4

PURPOSE: VERIFY IF DIAGNOSTIC RESULT IS AFFECTED BY DTC RELATED TO SAS CONTROL MODULE

•  Switch the ignition off, then ON (engine off).

•  Perform the SAS control module DTC inspection using the M-MDS.
(See DTC INSPECTION.)

•  Are any DTCs present?

Yes

Go to the applicable DTC inspection.

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

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

Go to Troubleshooting Diagnostic Procedure to perform the procedure from step 1.

No

Go to Troubleshooting Diagnostic Procedure to perform the procedure from step 1.

Troubleshooting Diagnostic Procedure

Intention of troubleshooting procedure

• Step 1

• Repair completion verification

― Verify that the primary malfunction is resolved and there are no other malfunctions.

Step

Inspection

Results

Action

1

PURPOSE: 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.)

•  Replicate the vehicle conditions at the time the DTC was detected using the following procedure.

―  (See Repeatability Verification Procedure.)

•  Perform the DTC inspection for the PCM.
(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 PCM, then go to the next step.
(See PCM REMOVAL/INSTALLATION [SKYACTIV-D 1.8].)

No

Go to the next step.

Repair completion verification

PURPOSE: VERIFY IF OTHER DTCs DISPLAYED

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

•  Are any other DTCs displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

No

DTC troubleshooting completed.
