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 stores a DTC if it receives a collision signal.

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

Repeatability Verification Procedure

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

2. Clear DTCs using the M-MDS. (See CLEARING DTC [PCM (SKYACTIV-D 2.2)])

3. Switch the ignition OFF, switch the ignition back ON, and leave for 5 s.

4. Using the M-MDS, verify that DTC U0151:00 is not displayed. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)])

Function Inspection Using M-MDS

Step

Inspection

Results

Action

1

PURPOSE: VERIFY IF SYMPTOM IS NORMAL OPERATION DUE TO 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.

No

Go to the next step.

2

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

•  Switch the ignition OFF, and then switch it ON (engine off).

•  Display SAS control module DTCs using the M-MDS.
(See DTC INSPECTION [SAS CONTROL MODULE (TWO-STEP DEPLOYMENT CONTROL SYSTEM)]

(See DTC INSPECTION [SAS CONTROL MODULE (ACTIVE BONNET)]

•  Is a DTC displayed?

Yes

Repair the malfunctioning location according to the applicable DTC troubleshooting.

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

(See DTC INSPECTION [SAS CONTROL MODULE (ACTIVE BONNET)]

Go to the troubleshooting procedure to perform the procedure from Step 1.

No

Go to the troubleshooting procedure to perform the procedure from Step 1.

Inspection

Results

Action

1

PURPOSE: PERFORM DTC INSPECTION AND VERIFY IF MALFUNCTIONING LOCATION IS PCM

•  Reconnect all disconnected connectors and hoses.

•  Refer to the [MEMORY CLEARING PROCEDURE] and clear the DTC.
(See CLEARING DTC [PCM (SKYACTIV-D 2.2)])

•  Implement the repeatability verification procedure.
(See Repeatability Verification Procedure)

•  Display the DTCs using the M-MDS.
(See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)])
