DTC U0125:00/U0125:88 [DYNAMIC STABILITY CONTROL (DSC)]

id0402b2879000

DTC

U0125:00, U0125:88

Combined sensor system (CAN2 line malfunction)

DETECTION CONDITION

•  U0125:00

―  The signal from the combined sensor is not within specification.

•  U0125:88

―  Open or short circuit in CAN system wiring harness is detected.

POSSIBLE CAUSE

•  Open or short circuit in the CAN2_L wiring harness between the following combined sensor terminal and DSC HU/CM terminal

―  Combined sensor terminal B—DSC HU/CM terminal AL

•  Open or short circuit in the CAN2_H wiring harness between the following combined sensor terminal and DSC HU/CM terminal

―  Combined sensor terminal C—DSC HU/CM terminal AO

•  Combined sensor malfunction

•  DSC CM malfunction

•  Poor connection at connectors (female terminal)

Diagnostic procedure

STEP	INSPECTION		ACTION
1	INSPECT COMBINED SENSOR SIGNAL (CAN2 LINE) FOR OPEN CIRCUIT • Disconnect the DSC HU/CM connectors. • Disconnect the combined sensor connectors. • Inspect for continuity between the following DSC HU/CM connector terminals (vehicle harness-side) and combined sensor connector terminals (vehicle harness-side): ― DSC HU/CM terminal AL—combined sensor terminal B (CAN2_L) ― DSC HU/CM terminal AO—combined sensor terminal C (CAN2_H) • Is there continuity?	Yes	Go to the next step.
1		No	Repair or replace the wiring harness, then go to Step 4.
2	INSPECT COMBINED SENSOR 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 AL—body ground (CAN2_L) ― DSC HU/CM terminal AO—body ground (CAN2_H) • Is there continuity?	Yes	Repair or replace the wiring harness, then go to Step 4.
2		No	Go to the next step.
3	INSPECT THE COMBINED SENSOR • Reconnect all disconnected connectors. Inspect the combined sensor. (See COMBINED SENSOR INSPECTION.) • Is the combined sensor normal?	Yes	Go to the next step.
3		No	Replace the combined sensor, then go to the next step. (See COMBINED SENSOR REMOVAL/INSTALLATION.)
4	VERIFY THAT THE SAME DTC IS NOT PRESENT • Clear the DTCs from the memory. (See ON-BOARD DIAGNOSIS [DYNAMIC STABILITY CONTROL (DSC)].) • Are the same DTCs present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the DSC CM, then go to the next step. (See DSC HU/CM REMOVAL/INSTALLATION [L.H.D.].) (See DSC HU/CM REMOVAL/INSTALLATION [R.H.D.].)
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.
