Inspection for DTCs not shown in DTC table

System wiring diagram

Diagnostic procedure

Step

Inspection

Action

1

 BATTERY INSPECTION

  • Refer to the battery inspection and inspect the battery.

    (See BATTERY INSPECTION.)

  • Is the battery normal?

Yes

Go to the next step.

No

Replace or charge the battery.

(See BATTERY REMOVAL/INSTALLATION [SKYACTIV-G 2.0].)

Then go to Step 5.

2

 FUSE INSPECTION

Yes

Go to the next step.

No

Replace the SRS1 7.5 A fuse.

Then go to Step 5.

3

 INSPECT WIRING HARNESS BETWEEN IG1 RELAY AND SAS CONTROL MODULE

WARNING:

NOTE:

  • Measure the voltage while shaking the wiring harness between the SAS control module and IG1 relay.

  • Is the voltage between 8―17.9 V?

Yes

Go to the next step.

No

Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and IG1 relay terminal.

    If there is a common connector:

  • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit or short to ground.

  • Replace the malfunctioning part.

    If there is no common connector:

  • Replace the wiring harness which has an open circuit or short to ground.

Go to Step 5.

4

 INSPECT SAS CONTROL MODULE CIRCUIT FOR OPEN CIRCUIT

  • SAS control module connectors are disconnected.

  • Switch the ignition off.

  • Disconnect the negative battery cable and wait 1 min or more.

    (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION.)

  • Inspect the wiring harness between SAS control module connector terminal 2X, 2AB (wiring harness-side) and body ground.

NOTE:

  • Inspect for continuity while shaking the wiring harness between the SAS control module and body ground.

  • Is there continuity?

Yes

Go to the next step.

No

Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and body ground.

    If there is a common connector:

  • Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.

  • Replace the malfunctioning part.

    If there is no common connector:

  • Replace the wiring harness which has an open circuit.

Go to the next step.

5

 PERFORM SAS CONTROL MODULE DTC INSPECTION

Yes

Replace the SAS control module.

(See SAS CONTROL MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

No

DTC troubleshooting completed.
