DTC

C0061:28, C0061:64, C0062:28, C0062:64, C0063:28, C0063:64

SAS control module system

DETECTION CONDITION

Note

•  The low-G sensor and the yaw rate sensor are built into the SAS control module.

•  C0061:28, C0061:64

―  Out-of-specification signal modulation or lateral-G value is detected from the low-G sensor.

•  C0062:28, C0062:64

―  Out-of-specification signal modulation or longitudinal-G value is detected from the low-G sensor.

•  C0063:28, C0063:64

―  Out-of-specification signal modulation or yaw rate value is detected from the yaw rate sensor.

FAIL-SAFE FUNCTION

Refer to “Fail-safe function table”. (See DTC TABLE [DSC HU/CM].)

POSSIBLE CAUSE

•  SAS control module malfunction

•  Open circuit or short to ground in wiring harness between DSC HU/CM terminal AF and FBCM terminal 2P

•  Open circuit or short to ground in wiring harness between DSC HU/CM terminal AC and FBCM terminal 2N

•  Open circuit or short to ground in wiring harness between FBCM terminal 2K and SAS control module terminal 3Q

•  Open circuit or short to ground in wiring harness between FBCM terminal 2I and SAS control module terminal 3S

•  DSC HU/CM malfunction

•  Poor connection at connectors (female terminal)

Diagnostic procedure

STEP	INSPECTION		ACTION
1	INSPECT SAS CONTROL MODULE MALFUNCTION • Switch the ignition off. • Using the M-MDS, perform the DTC inspection for the SAS control module. (See DTC INSPECTION [SAS CONTROL MODULE (STANDARD DEPLOYMENT CONTROL SYSTEM)].) (See DTC INSPECTION [SAS CONTROL MODULE (TWO-STEP DEPLOYMENT CONTROL SYSTEM)].) • Are any DTCs detected?	Yes	Go to applicable DTC inspection. (See DTC TABLE [SAS CONTROL MODULE (STANDARD DEPLOYMENT CONTROL SYSTEM)].) (See DTC TABLE [SAS CONTROL MODULE (TWO-STEP DEPLOYMENT CONTROL SYSTEM)].) After completing the applicable DTC troubleshooting, go to Step 5.
1		No	Go to the next step.
2	INSPECT SAS CONTROL MODULE SIGNAL CIRCUIT (CAN 2 LINE) FOR OPEN CIRCUIT • Switch the ignition off. • Disconnect DSC HU/CM connector. • Disconnect FBCM connector. • Disconnect SAS control module connector. • Inspect for continuity between the following DSC HU/CM connector and SAS control module vehicle wiring harness-side connector terminals. ― DSC HU/CM terminal AF and FBCM terminal 2P ― DSC HU/CM terminal AC and FBCM terminal 2N ― FBCM terminal 2K and SAS control module terminal 3Q ― FBCM terminal 2I and SAS control module terminal 3S • Is there continuity?	Yes	Go to the next step.
2		No	Repair or replace the wiring harness, then go to Step 5.
3	INSPECT FBCM SIGNAL CIRCUIT (CAN 2 LINE) FOR SHORT TO GROUND • Inspect for continuity between the following DSC HU/CM connector terminals (vehicle wiring harness side) and body ground. ― DSC HU/CM terminal AF and body ground ― DSC HU/CM terminal AC and body ground • Is there continuity?	Yes	Repair or replace the wiring harness, then go to step 5.
3		No	Go to the next step.
4	INSPECT SAS CONTROL MODULE SIGNAL CIRCUIT (CAN 2 LINE) FOR SHORT TO GROUND • Inspect for continuity between the following FBCM connector terminals (vehicle wiring harness side) and body ground. ― FBCM terminal 2K and body ground ― FBCM terminal 2I and body ground • Is there continuity?	Yes	Repair or replace the wiring harness, then go to the next step.
4		No	Go to the next step.
5	VERIFY THAT THE SAME DTC IS NOT PRESENT • Reconnect all disconnected connectors. • Clear the DTCs from the memory. (See CLEARING DTC [DSC HU/CM].) • Start the engine and drive the vehicle at 10 km/h {6.2 mph} or more. • Using the M-MDS, perform the DSC HU/CM DTC inspection. (See DTC INSPECTION [DSC HU/CM].) • Is the same Pending DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the DSC HU/CM, then go to the next step. (See DSC HU/CM REMOVAL/INSTALLATION [SKYACTIV-G 2.5].) (See DSC HU/CM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
5		No	Go to the next step.
6	VERIFY THAT NO OTHER DTCS ARE PRESENT • Are any other DTCs output?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [DSC HU/CM].)
6		No	DTC troubleshooting completed.
