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

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

Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC [SKYACTIV-G 2.5].)

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: VERIFY RELATED REPAIR INFORMATION AVAILABILITY Verify related Service Bulletins and/or on-line repair information availability. Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. If the vehicle is not repaired, go to the next step.
1		No	Go to the next step.
2	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 the troubleshooting procedure to perform the procedure from Step 1.
2		No	Go to the next step.
3	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 [STANDARD DEPLOYMENT CONTROL SYSTEM].) (See DTC INSPECTION [TWO-STEP DEPLOYMENT CONTROL SYSTEM].) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [STANDARD DEPLOYMENT CONTROL SYSTEM].) (See DTC TABLE [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)
3		No	Go to the troubleshooting procedure to perform the procedure from Step 1.

Troubleshooting Diagnostic Procedure

Intention of troubleshooting procedure

Step 1—2

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


STEP	INSPECTION	RESULTS	ACTION
1	PURPOSE: PERFORM DTC INSPECTION AND VERIFY IF MALFUNCTIONING PART IS PCM Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC [SKYACTIV-G 2.5].) Implement the repeatability verification procedure. (See Repeatability Verification Procedure.) Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-G 2.5].) Is the same DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.5].) Go to the next step.
1		No	Go to the next step.
2	PURPOSE: VERIFY IF THERE IS ANY OTHER MALFUNCTION Is any other DTC or pending code stored?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [SKYACTIV-G 2.5].)
2		No	DTC troubleshooting completed.
