DTC B1206:00/B143A:00/B1A55:00/U2107:00 [SAS CONTROL MODULE (TWO-STEP DEPLOYMENT CONTROL SYSTEM)]

id0802g8015000

System malfunction location

•  B1206:00: SAS control module collision judgement signal output (fuel cut off signal output)

•  B143A:00: SAS control module collision judgement signal output (collision detection signal output)

•  B1A55:00: SAS control module collision judgement signal output (collision detection signal for MAZDA ERA-GLONASS output)

•  U2107:00: SAS control module collision judgement signal output (ESS signal output)

Detection condition

Warning

•  Detection conditions are for understanding the DTC outline before performing an inspection. Performing an inspection according to only the detection conditions may cause injury due to an operating error, or damage the system. When performing an inspection, always follow the inspection procedure.

•  B1206:00: SAS control module detects collision and outputs fuel cut off signal

•  B143A:00: SAS control module detects collision and outputs collision detection signal

•  B1A55:00: SAS control module detects collision and outputs collision detection signal for MAZDA ERA-GLONASS

•  U2107:00: SAS control module detects collision and outputs ESS signal

Fail-safe function

Not applicable

Possible cause

•  Vehicle collision

•  SAS control module outputs fuel cut off signal

•  SAS control module outputs collision detection signal

•  SAS control module outputs collision detection signal for MAZDA ERA-GLONASS

•  SAS control module outputs ESS signal

•  SAS control module malfunction

Diagnostic Procedure

Step

Inspection

Action

1

PERFORM SAS CONTROL MODULE DTC INSPECTION

•  Clear the DTC for the SAS control module using the M-MDS.
(See CLEARING DTC [SAS CONTROL MODULE (TWO-STEP DEPLOYMENT CONTROL SYSTEM)].)

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

•  Are the same DTCs present?

Yes

Repeat the inspection from Step 1.

•  If the malfunction recurs, replace the SAS control module.
(See SAS CONTROL MODULE REMOVAL/INSTALLATION [TWO-STEP DEPLOYMENT CONTROL SYSTEM].)

No

DTC troubleshooting completed.
