2	VERIFY PUMP MOTOR OPERATION Switch the ignition to off. Connect the M-MDS to the DLC-2. Switch the ignition to ON. Access PMP_MTR active command modes using the M-MDS. Does the pump motor operate?	Yes	Go to the next step.
2		No	Replace the DSC HU/CM, then go to Step 6. (See DSC HU/CM REMOVAL/INSTALLATION .)
3	INSPECT MOTOR RELAY POWER SUPPLY FOR OPEN CIRCUIT Switch the ignition to off. Disconnect the DSC HU/CM connector. Inspect for continuity between DSC HU/CM terminal AT (vehicle harness-side) and the positive battery terminal. Is there continuity?	Yes	Go to the next step.
3		No	Repair or replace the wiring harness, then go to Step 6.
4	INSPECT MOTOR RELAY POWER SUPPLY FOR SHORT CIRCUIT Inspect for continuity between DSC HU/CM terminal AT (vehicle harness-side) and body ground. Is there continuity?	Yes	Repair or replace the wiring harness, then go to Step 6.
4		No	Go to the next step.
5	INSPECT PUMP MOTOR GROUND FOR OPEN CIRCUIT Inspect for continuity between DSC HU/CM terminal B (vehicle harness-side) and body ground. Is there continuity?	Yes	Go to the next step.
5		No	Repair or replace the wiring harness, then go to the next step.
6	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 .)
6		No	Go to the next step.
7	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)] .)
