DTC

B10DF:46, C1A08:1C, U2007:46, U2007:62, U3000:49

DSC HU/CM (internal malfunction)

DETECTION CONDITION

•  The DSC CM on-board diagnostic function detects control module internal malfunction.

FAIL-SAFE FUNCTION

•  B10DF:46, U2007:46

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

―  Inhibits the TCS, DSC, roll over mitigation (ROM), brake assist control, vehicle roll prevention function^*2, hill launch assist (HLA), smart city brake support (SCBS)^*1, and secondary collision reduction (SCR) controls.

•  C1A08:1C

―  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), brake assist control, vehicle roll prevention function^*2, hill launch assist (HLA), TPMS, smart city brake support (SCBS)^*1, and secondary collision reduction (SCR) controls.

•  U2007:62

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

―  Inhibits the ABS, EBD, TCS, DSC, roll over mitigation (ROM), brake assist control, vehicle roll prevention function^*2, hill launch assist (HLA), smart city brake support (SCBS)^*1, and secondary collision reduction (SCR) controls.

•  U3000:49

―  Illuminates the ABS warning light^*3, brake system warning light^*3, TCS/DSC indicator light, and master warning light^*1.

―  Tire pressure monitoring system warning light illuminates after flashes. (Not illuminated/flashed depending on malfunction content.)

―  Inhibits the ABS^*4, EBD^*4, TCS, DSC, roll over mitigation (ROM), brake assist control^*4, vehicle roll prevention function^*2, hill launch assist (HLA), TPMS^*4, smart city brake support (SCBS)^*1, and secondary collision reduction (SCR) controls.

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

^*2: ATX only

^*3: Not illuminated depending on malfunction content.

^*4: Enabled depending on malfunction content.

POSSIBLE CAUSE

•  DSC HU/CM internal malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY NO DSC HU/CM MALFUNCTION • Clear the DTCs from the memory. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].) • Start the engine and drive the vehicle at 10km/h {6.2 mph} or more. • Are the same DTCs present?	Yes	Replace the DSC HU/CM, then go to the next step. (See DSC HU/CM REMOVAL/INSTALLATION.)
1		No	Go to the next step.
2	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)].)
2		No	DTC troubleshooting completed.
