Diagnostic Procedure

WARNING: This page is about a different car, the 2017 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.
DIAGNOSTIC PROCEDURE

Step Inspection Action
1 INSPECT PASSENGER-SIDE AIR BAG MODULE CONNECTOR
WARNING:
Yes Replace the malfunctioning part, then go to Step 8.
No Go to the next step.
2 INSPECT PASSENGER-SIDE AIR BAG MODULE CIRCUIT FOR SHORT TO GROUND Yes Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and passenger-side air bag module 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 a short to ground.
  • Replace the malfunctioning part. If there is no common connector:
  • Replace the wiring harness which has a short to ground.

Go to Step 8.
No Go to the next step.
3 INSPECT PASSENGER-SIDE AIR BAG MODULE CIRCUIT FOR OPEN CIRCUIT
  • Passenger-side air bag module and SAS control module connectors are disconnected.
  • Inspect for continuity between the following terminals (wiring harness-side):
    • Passenger-side air bag module terminal 1A- SAS control module terminal 3L
      • Passenger-side air bag module terminal 1B-SAS control module terminal 3M
    NOTE:
    • Inspect for continuity while shaking the wiring harness between the SAS control module and passenger-side air bag module.
  • 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 passenger-side air bag module 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.
  • Replace the malfunctioning part.

    If there is no common connector:

  • Replace the wiring harness which has an open circuit.

Go to Step 8.
4 INSPECT PASSENGER-SIDE AIR BAG MODULE CIRCUIT FOR SHORT TO EACH OTHER
  • Passenger-side air bag module and SAS control module connectors are disconnected.
  • Inspect for continuity between the following terminals (wiring harness-side):
    • SAS control module terminal 3M- SAS control module terminal 3L
    NOTE:
    • Inspect for continuity while shaking the wiring harness between the SAS control module and passenger-side air bag module.
  • Is there continuity?
 Yes Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and passenger-side air bag module 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 a short to each other.
  • Replace the malfunctioning part.

    If there is no common connector:

  • Replace the wiring harness which has a short to each other.

Go to Step 8.
No Go to the next step.
5 INSPECT PASSENGER-SIDE AIR BAG MODULE CIRCUIT FOR SHORT TO OTHER AIR BAG MODULE CIRCUIT
  • Passenger-side air bag module and SAS control module connectors are disconnected.
  • Other air bag module and pre-tensioner seat belt connectors are disconnected.
  • Refer to the wiring diagram and inspect for continuity between the following terminals and other air bag module/pre-tensioner seat belt terminals (wiring harness-side).
    • SAS control module terminal 3L
      • SAS control module terminal 3M
    NOTE:
    • Inspect for continuity while shaking the wiring harness between the SAS control module and passenger-side air bag module.
  • Is there continuity?
 Yes Refer to the wiring diagram and verify whether or not there is a common connector between SAS control module terminal and passenger-side air bag module 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 a short to other air bag module or pre-tensioner seat belt circuit.
  • Replace the malfunctioning part.

    If there is no common connector:

  • Replace the wiring harness which has a short to other air bag module or pre-tensioner seat belt circuit.

Go to Step 8.
No Go to the next step.
6 INSPECT PASSENGER-SIDE AIR BAG MODULE CIRCUIT FOR SHORT TO POWER SUPPLY
  • Passenger-side air bag module and SAS control module connectors are disconnected.
  • Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)
  • Switch the ignition ON (engine off or on).
  • Measure the voltage at the following terminals (wiring harness-side):
    • SAS control module terminal 3L
      • SAS control module terminal 3M
    NOTE:
    • Measure the voltage while shaking the wiring harness between the SAS control module and passenger-side air bag module.
  • Is the voltage 0 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 passenger-side air bag module 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 a short to power supply.
  • Replace the malfunctioning part.

    If there is no common connector:

  • Replace the wiring harness which has a short to power supply.

Go to Step 8.
7 INSPECT PASSENGER-SIDE AIR BAG MODULE Yes Go to the next step.
No Replace the passenger-side air bag module. (See PASSENGER-SIDE AIR BAG MODULE REMOVAL [STANDARD DEPLOYMENT CONTROL SYSTEM] .) (See PASSENGER-SIDE AIR BAG MODULE INSTALLATION [STANDARD DEPLOYMENT CONTROL SYSTEM] .)
Then go to the next step.
8 PERFORM SAS CONTROL MODULE DTC INSPECTION Yes Repeat the inspection from Step 1.
No DTC troubleshooting completed.
