CMDTC Self Test
1. Connect the M-MDS to the DLC-2.
2. After the vehicle is identified, select the following items from the initialization screen of the M-MDS.
3. Verify the DTC according to the directions on the screen.
4. After completion of repairs, clear all DTCs stored in the DC-DC converter (i-ELOOP). (See CLEARING DTC [i-ELOOP].)
