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

•  C0061:28, C0061:64, C0063:28, C0063:64

―  Illuminates the TCS/DSC indicator light and master warning light^*1.

―  Tire pressure monitoring system warning light illuminates after flashes.

―  Inhibits the TCS, DSC, roll over mitigation (ROM), TPMS, smart city brake support (SCBS)^*1, and secondary collision reduction (SCR) controls.

•  C0062:28, C0062:64

―  Illuminates the ABS warning light^*2, TCS/DSC indicator light, and master warning light^*1*2.

―  Inhibits the ABS^*3, TCS^*3, DSC^*3, roll over mitigation (ROM)^*3, brake assist control^*3, vehicle roll prevention function^*4, hill launch assist (HLA), smart city brake support (SCBS)^*1*3, and secondary collision reduction (SCR)^*3 controls.

^*1: Vehicles with smart city brake support (SCBS)

^*2: Not illuminated depending on malfunction content.

^*3: Enabled depending on malfunction content.

^*4: ATX only

POSSIBLE CAUSE

•  SAS control module malfunction

•  Open or short circuit in the CAN2_H wiring harness between DSC HU/CM terminal S and SAS control module terminal 3H

•  Open or short circuit in the CAN2_L wiring harness between DSC HU/CM terminal P and SAS control module terminal 3I

•  DSC HU/CM malfunction

•  Poor connection at connectors (female terminal)

Diagnostic procedure

STEP	INSPECTION		ACTION
1	INSPECT SAS CONTROL MODULE MALFUNCTION • Switch the ignition to off. • Using the M-MDS, perform the DTC inspection for the SAS control module. (See DTC INSPECTION.) • Are any DTCs detected?	Yes	Go to applicable DTC inspection. (See DTC TABLE.)
1		No	Go to the next step.
2	INSPECT SAS CONTROL MODULE SIGNAL (CAN2 LINE) FOR OPEN CIRCUIT • Disconnect the DSC HU/CM connector. • Disconnect the SAS control module connectors. • Inspect for continuity between the following DSC HU/CM connector terminals (vehicle harness-side) and SAS control module connector terminals (vehicle harness-side): ― DSC HU/CM terminal S—SAS control module terminal 3H ― DSC HU/CM terminal P—SAS control module terminal 3I • Is there continuity?	Yes	Go to the next step.
2		No	Repair or replace the wiring harness, then go to Step 4.
3	INSPECT SAS CONTROL MODULE SIGNAL (CAN2 LINE) FOR SHORT CIRCUIT • Inspect for continuity between the following DSC HU/CM connector terminals (vehicle harness-side) and body ground: ― DSC HU/CM terminal S—body ground ― DSC HU/CM terminal P—body ground • Is there continuity?	Yes	Repair or replace the wiring harness, then go to the next step.
3		No	Go to the next step.
4	VERIFY THAT THE SAME DTC IS NOT PRESENT • Reconnect all disconnected connectors. • Clear the DTCs from the memory. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].) • Start the engine and drive the vehicle at 10 km/h {6.2 mph} or more. • Are the same DTCs 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.)
4		No	Go to the next step.
5	VERIFY THAT NO OTHER DTCS ARE PRESENT • Are any other DTCs output?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].)
5		No	DTC troubleshooting completed.
